The purpose of this study is to determine the quality of oilseed rape seeds, produced at various locations, immediately after harvest and after a one-year storage period under controlled and uncontrolled conditions. The experimental testing was performed on seeds of five winter oilseed rape varieties produced at two localities (Rimski Šančevi and Pančevo). Following harvest and a one-year storage period, the seed quality was determined under laboratory conditions using standard germination tests. Seed germination, seedling length and vigour index were determined after seven days. The seed germination, length of seedling and vigour index values of the seeds produced at both localities were lower after one year of storage. Differences obtained between the seeds stored under controlled and uncontrolled conditions were not statistically significant. The seeds with higher initial values of all the tested parameters proved better under storage conditions.

Oilrape is used for human consumption, domestic animal consumption, for biodiesel production, as bee pasture and as an important green manure. This crop is tolerant to many soil types (including saline soils) in the growing regions across the globe. Testing was done on three oilrape winter varieties: Ana, Slavica and Ilia. The influence of salinity on seed quality was determined after the harvest using standard laboratory methods under laboratory conditions. Seed germination in the control ranged from 92.75 % do 96 %. As NaCl concentration increased from 150 mmol/l to 250 mmol/l, germination decreased, and statistically the lowest values were obtained at the concentration of 300 mmol/l in Slavica and Ilija varieties (57-84 %). In all studied genotypes, the first seedlings emerged after three days of testing in the control and at NaCl concentrations of 75 mmol/l, 100 mmol/l, 150 mmol/l and 200 mmol/l. The seed germinated on the medium moisturized with 250 mmol/l NaCl started to germinate after four days of testing, while the seed germinated on the medium moisturized with 300 mmol/l NaCl started germination after five days. The length of seedlings was statistically the most significant in the control in all three varieties. Statistically the lowest values were obtained in the seedlings at NaCl concentration of 300 mmol/l. For successful production under stress conditions, adaptable genotypes which have pronounced positive interaction with environmental conditions should be chosen.

According to the surfaces on which the oil rape is grown, it is considered the third most important oil crop of moderate climate zone in the world today. The aim of this paper was to determine the seed viability by application of both the standard laboratory test and the vigor tests. Testing was done using 9 oil rape genotypes (three winter varieties: Slavica, Zlatna and Ilija; three spring varieties: Mira, Jovana and JR-NS-7; three hybrids NS-UR 4, NS-UR 6 and NS-UR 13). Seed germination, seedling growth parameters, fresh seedling mass, and vigor index were determined using standard laboratory (SL) test, accelerated aging (AA) test, and controlled deterioration (SD) test. With applied SL test, on average, statistically significantly higher values for all tested parameters were obtained in comparison to AA and CD tests. By calculating the vigor index genotypes Zlatna, JR-NS 7, NS-UR 4, NS-UR 6 and NS-UR 13 were singled out, in which statistically significantly higher values were obtained with SL in relation to AA and CD tests.

Rapeseed is an important industrial plant in the world. In Vojvodina region of Serbia it is grown on well aerated and deep soils. Most often it is sown with the distance between the rows of 25 cm, and 5-6 cm within the row. The trial with three winter rapeseed genotypes (Banaćanka, Slavica and NS-H-2) was set up at Rimski Šančevi (Vojvodina) during growing seasons of 2009/2010 and 2010/2011. Seed was sown with inter row spacing of 25 cm, and spacing within the rows of 5 cm, 8 cm, 10 cm and 16 cm. The following parameters were tested upon harvesting: seed germination, 1000 seed weight, test weight, seed yield, oil content and total protein in seed. No effect of planting density was observed on rapeseed seed quality produced in 2009/10 and 2010/11, which should be kept in mind when determining the quantity of seed required for sowing.

Due to its composition the oilseed rape is widely used in the production of oil, animal feed and biodisel production. Due to a wide range of rapeseed use, the aim of this paper was to determine the influence of genotype, production year and planting density on seed germination, seed moisture content, mass of 1000 seed, hectoliter mass, seed yield per plot, and oil and protein content in the seed. Tests were carried out on four rapeseed genotypes sown at a distance of 5 cm (80 plants/m2), 10 cm (40 plants/m2), 15 cm (27 plants/m2) and 20 cm (20 plants/m2) within the raw during 2007/2008 and 2008/2009 vegetation period. Seed germination, hectoliter mass and seed yield depended on production year, mass of 1000 seeds depended on genotype, plant density and production year, while the oil and protein content depended on genotype and production year.

Rapeseed (Brassica napus L) is widely used in the production of oil, animal feed and biodiesel. Quality of oilseed rape depends on the genotype meteorological conditions and crop management. It is important to provide sufficient quantities of soil nutrients before planting (basal fertilization), so that young plants may form a leaf rosette and prepare for a period of low winter temperature. This research was performed on four commercial genotypes of rapeseed (Banaćanka, Slavica, Express and Valeska) produced in the growing season 2008-2009. The following parameters were determined: germination, 1000-seed weight, oil content and fatty acids. Seed germination, 1000-seed weight and oil content depended on the genotype, but not on the applied NPK dose. The fatty acids content depended on the genotype and the amount of fertilizer applied.

Barley is one of the most important cereals grown in our agroecological conditions. The causal agent of loose smut on barley Ustilago nuda (Jensen) Rostrup occurs frequently as varieties susceptible to this pathogen are present in the production. Disease symptoms are manifested on barley head (spike). Parasite is transmitted by seed (seedborne) and stays in the embryo tissue of the infected kernel as dormant mycelium. Recommended method for detection of U. nuda is given by ISTA Rules (method 7-013). In tests, nine samples (weighing 120 g each) of naturally infected barley seed (about 1000 seeds, depending on the absolute mass of seed) were examined, observed and described using a Zeiss microscope with sub stage illumination with magnification range x 40 or higher. Mycelium of the fungus approximately 3 μ thick, golden brown in colour was detected and visible without a stain. The percentage of infected embryos in the examined samples of barley seeds ranged from 0.8% to 5.2%.

Common vetch (Vicia sativa L), hairy vetch (Vicia villosa Roth), and Pannonian vetch (Vicia pannonica Crantz) are the most often grown varieties in the production area of Serbia. The most important problem in the production of vetch seed is lodging. Yield and seed quality in lodged crops can be significantly reduced. Therefore, it is very important to accurately estimate the quality, and viability of produced seed. Common vetch, hairy vetch and Pannonian vetch were submitted to vigor testing using standard laboratory test, cold test, Hiltner test, and three variants of accelerated aging tests (39°C,72 h; 39°C, 96 h; 45°C, 48 h). When the standard laboratory test was applied, the common vetch achieved the highest seed germination value of 90%, while decreased rate of seed germination was due to unfavorable conditions applied in vigor tests. Above ground seedling growth parameters were the lowest when Hiltner test was applied. Length and mass of the root system were the lowest when accelerated aging test was applied. Hairy vetch obtained the lowest values for all tested parameters when Hiltner test was applied. Application of different variants of accelerated aging tests indicated that tested parameters were not dependent on the applied temperature, while reduction in legumes vigor was under the influence of temperature duration.

Carrot is among the most important vegetable crops because of its composition and vitamin content. The fungi belonging to genus Alternaria, especially A. dauci (Kühn) Groves et Skolk, causal agent of leaf spot and blight of carrots, and A. radicina Meier, Drechsler et Eddy, the agent of black root rot, can jeopardize the entire production of carrots. Both types can be found in a high percentage of seeds, carrots, parsley and celery. The method of detection filter paper (blotter method) and the method of isolation on malt agar were recommended by ISTA Rules. The presence of A. dauci (causal agent of leaf spot and blight of carrots) and A. radicina was performed on 12 samples of potentially infected carrot seeds originating from France, as part of laboratory ring tests. The presence of A. dauci and A. radicina using the filter paper method in 12 tested samples ranged from 0% to 21% and from 1% to 30% respectively. On MA medium the respective percentages ranged from 0% to 23% and from 1% to 31%.

Oilseed rape is an agronomically important species grown for seed that contains 40-48% oil and 18-25% proteins. Oilseed rape has high demands for nitrogen. The research was performed on four varieties of oilseed rape (Banaćanka, Valeska, Slavica and Express) developed at Institute of Field and Vegetable Crops in Novi Sad, during vegetative seasons 2007-2008 and 2008-2009. During vegetation, top dressing was applied with different amounts of KAN: control (0 kg N ha-1), 50 kg N ha-1, 100 kg N ha-1, 150 kg N ha-1 and the N quantity determination were performed applying the balancing method (also known as N-min method). Yield, 1000-seed weight, seed germination, oil and protein content were determined after harvest. Yield and seed germination depended on seed production year. 1000-seed weight depended on seed production year and genotype. Oil and protein content in seed depended on production year, genotype and amount of the N-fertilizer applied by top dressing.

A large number of microorganisms' parasite on maize seed. The most important of them are fungi. Blotter method and method of nutrient medium were used to examine the seed health of 90 maize seed samples from eight seed processing centres in the period 2006-2008. The presence of fungi from the genera Fusarium, Penicillium, Aspergillus and Rhizopus was observed on maize seed. According to current regulations, level of infection caused by the fungi observed in all three years was within the normal limits. The percentage of infected samples was 45% in 2006, 40% in 2007, and 32% in 2008. Percentage of infection ranged from 0.25% to 5% in samples where the presence of fungi of the genus Fusarium was detected, while the percentage of infection on maize seed caused by the fungi from saprophite group (Penicillium spp., Aspergillus spp. and Rhizopus spp.) ranged within the limits of 0.25% to 15%.

The effect of seed moisture content at harvest on the most important parameters of dry pea was examined. The seed moisture content, germination energy, germination, proportion of abnormal seedlings and 1000-seed weight were analyzed in three dry pea cultivars (Jezero, Javor and NS-Junior) and at eight harvest stages. At the first harvest stage, seed moisture content was 20.44%, while at the eighth stage it was 11.26%. The best seed quality, with germination energy of 81.70% and germination of 90.11%, was at the sixth harvest time when seed moisture content was 12.92%. The poorest seed quality one was at the first harvest stage, with germination energy of 68.55% and germination of 78.56%. Cultivar Jezero, with shorter growing season, determinant stem growth and uniform maturity, had the highest germination energy (82.00%), germination (92.21%) and percent of abnormal seedlings (1.96%). Cultivar NS Junior, with the longest growing season, indeterminant stem growth and non-uniform maturity, had the lowest germination energy (70.39%) and germination (76.54%), and the highest percent of abnormal seedlings (3.58%).

Pepper is a very popular and profitable crop in Serbia and its production is growing rapidly as well as the importance of diseases caused by viruses. Virus infections interfere with development of pepper plants, reducing yield and fruit quality. More than 45 viruses have been isolated from pepper so far, and in our country the following are considered economically very important: Tobacco mosaic virus (TMV), Cucumber mosaic virus (CMV), Alfalfa mosaic virus (AMV), Tomato spotted wilt virus (TSWV) and Potato virus Y (PVY). During 2009, an investigation was conducted regarding the presence and distribution of pepper viruses in Serbia, which included a survey of different localities of transplant production, and both greenhouse and open field pepper crops. Collected samples were tested utilizing a double-antibody sandwich enzyme-linked immunosorbent assay (DAS-ELISA) with polyclonal antisera specific for the detection of economically important pepper viruses: PVY, AMV, CMV, TSWV, TMV and Potato virus X (PVX). In the collected samples, presence of the four viruses (PVY, CMV, TSWV and AMV) was confirmed in single and mixed infections. In tested transplant samples, the most frequently detected virus was CMV (18.18%), while PVY was the most frequent in samples collected in greenhouse and open field pepper crops (32.56% and 51.21% respectively). The presence of TSWV was detected only in greenhouse-grown pepper crops, while the presence of PVX and TMV was not detected during this investigation. The obtained results indicated that PVY and CMV were widely distributed and the most frequent viruses in pepper crops in Serbia. Future investigation should include their detailed biological and molecular characterization, as well as the implementation of appropriate control measures in pepper productions.

Field pea (Pisum sativum L.) seed contains a large amount of proteins, amino acids, sugars, carbohydrates, vitamins A and C, calcium and phosphorous, and hence it is widely used for many purposes. Although field pea has moderate requirements for its growth, it is sensitive to increased salt content in soil. This research included eight varieties (Javor, Jantar, Partner, Kristal, Pionir, Junior, Trezor, Dukat) developed at Institute of Field and Vegetable Crops in Novi Sad. Sodium chloride solutions of various concentrations (0, 50, 100 and 150 mM) were added in growing media to simulate saline conditions. The following were subsequently determined: seed germination, seedling length, fresh and dry weight of seedlings and 1000-seed weight. Among the analyzed varieties, variety Jantar expressed a high level of tolerance to increased salt content in growing media under laboratory conditions.

This work describes the incidence and distribution of the most important bean viruses in Serbia: Bean common mosaic virus (BCMV), Bean common mosaic necrosis virus (BCMNV), Bean yellow mosaic virus (BYMV), Cucumber mosaic virus (CMV) and Alfalfa mosaic virus (AMV). The viral isolates were characterized serologically and biologically. BCMV was found in the largest number of plants (30.53%), followed by BCMNV (2.67%), CMV (5.34%), and AMV (3.41%), since BYMV was not determined. Mixed viral infections were found in several samples. The RT-PCR method was used to prove that the tested isolates belong to the BCMV, family Potyviridae and strains Russian and NL-3 D. Results obtained in this work will enable further studies of the genetic variability of bean virus isolates from Serbia. .

One of the main features that confer high quality to the seed is its genetic purity. Genetic impurities in sunflower seed lot can originate from seed due to self-pollination, uncontrolled cross-pollination or mechanical mixing of seeds. Genetic purity of 18 seed lots of sunflower parental lines is controlled by comparative analysis of morphological traits and electrophoretic analysis 4 isoenzyme systems, according to the UPOV guidelines for DUS test of sunflower lines and hybrids. In 83.3% of the total analysed samples, results in the field and laboratory were in agreement. In parental line R-8 5% genetic impurity was found by isoenzyme analysis, which was not detected based on morphological characteristics, while electrophoretic analysis of samples L-10 and L-11 showed less genetic impurities in comparison with the analysis in the field. .

The biochemical marker phaseolin and isozymes were used in this work to display the variation of common bean germ plasma. Fifteen bean genotypes of different origin i. e. selections were studied. From 8 analyzed enzymic systems, enzymes MDH, SKDH, ME and IDH were polymorphic, while there were no differences in zymograms for enzymes PGM, PHI, PGD, and ADH. Analysis of phaseolin revealed two types: S and T. The S type of phaseolin was found in most of analyzed genotypes (9). Phaseolin type T was found in varieties of Novi Sad selection: Zlatko, Sremac and Aster, domestic population Žuto-zeleni Stepanovićevo and Jovandeka, Croatian variety Slavonski žuto-zeleni. Those varieties were developed from domestic populations from north-west region of Balkan, Slavonia, and Vojvodina.

At the same time as development and registration of new genetic modification of plant species have intensified, the number of countries in which they are grown has also increased considerably. Genetically modified crops were grown in 22 countries in 2006, six of which were in European Union. Protocol on Biosafety, known as Cartagena protocol was adopted at the international level in February, 2000. Presence, but not growing of GMO in food is allowed in many countries, while in some others labeling of food origination from GMO is obligatory. Labeling is obligatory in European Union, Australia, New Zealand, Japan, Norway, Switzerland and some others. In our country the Law on GMO and sub-law acts were conceived according to EU regulative. The terms for limited use, production, trade of GMO and GMO products have been prescribed. Validation and standardization of GMO testing methods are now being implemented. It is expected that the analytical GMO methods will soon be harmonized at the international level. .

Assuming that drought affects corn seed performance, such conditions were simulated in this study in order to examine their effects on seedling geminability and length in several corn genotypes. The study showed that the tested seeds tolerated the stress conditions up to a certain point. The studied genotypes differed in level of resistance to the stress conditions. Salt concentrations were determined, which were capable of negatively affecting seed germinability and seedling growth.

The agricultural biotechnology applies polymerase chain reaction (PCR) technology at numerous steps throughout product development. The major uses of PCR technology during product development include gene discovery and cloning, vector construction, transformant identification, screening and characterization as well as seed quality control. Commodity and food companies as well as testing laboratories rely on PCR technology to verify the presence or absence of genetically modification (GM) in a product or to quantify the amount of GM material present in the product. This article describes the fundamental elements of PCR analysis and its application to the testing of grains and highlights some of areas to which attention must be paid in order to produce reliable test results. The article also discuses issues related to the analysis of different matrixes and the effect they may have on the accuracy of the PCR analytical results.

A study has been conducted in order to assess genetic variability in three maize populations, which are part of breeding material of Institute of Field and Vegetable Crops in Novi Sad. Variability has been analyzed for seven enzymes. PGM enzyme was monomorphic while enzymes ACP, GLU, IDH, MDH, PHI and PGD had from 2 to 5 alleles. In the total sample which consisted of 228 lines, 34 alleles were found. The greatest variability was found in Pgd1 and Pgd2. The average heterozygosities of loci per population were from 0.203 to 0.274, and polymorphism varied between 0.727 and 0.818. The genetic distances and heterozigosities among the populations marked them as suitable material for selecting parental pairs in development of maize hybrids.

Newly developed soybean varieties differ from each other in morphological characteristics, requirements for growing conditions and technological quality of seed. The mentioned differences affect quality of seed and its viability. The aim of this paper was to determine seed quality of new soybean varieties differing in protein and oil content, and in maturity groups. Testing of seed quality was carried out on new soybean varieties developed in the Institute of field and vegetable crops in Novi Sad (NS Zenit, NS Virtus, Galina, Valjevka, Diva, NS Maximus, Sava, Balkan, Idila, Rubin, Trijumf and Vojvođanka) in the Laboratory of agricultural expert service in Novi Sad. The following seed quality traits were determined: seed moisture content, bulk density and germination of seed. Seed moisture content determined immediately after harvest ranged from 8.5% to 12.5%, and hectoliter weight from 65.5 kg/hl to 71.3 kg/hl. Statistically significant differences were found among studied varieties. The lowest values of germination were obtained in Sava (78%) and Vojvođanka (79%), and the highest in Rubin (96%) variety, while the seed germination determined by applied cold test was slightly lower. .

Isozymes can serve as genetic markers and their number should be large enough in order to make the coverage of genomes as complete as possible and in order to use these methods for gene marking for required agronomic traits. These markers are the products of 21 mapped genes, which is relatively reliable number for their application in mapping for certain agronomic traits. Genetic variability and diversity are significant for populations and for selfpolinated lines as basic material in breeding and creation of new corn hybrids. For that reason, several groups of corn populations of different origin were analyzed. Two groups of Yugoslav populations, Italian, Portuguese and French collections were assessed on the basis of detected alleles of 21 loci and standard genetic distances between genotypes. Yugoslav corn collections had shown high heterozygosity, on the basis of isozymes as gene markers. Genetic diversity of Italian populations was pronounced on the basis of some loci, and the Portuguese populations had more polymorphic and more heterozygous loci than French populations Inter-genetic variability between populations and their geographical location are very important in breeding crops for creation of heterosis.

International seed trade considers seed germination as the main indicator of the seed quality. Different results of seed germination under laboratory conditions and emergence in the field encouraged the development of the concept of the seed vigor and the term of vigor. Seed viability or vigor presents a set of those traits that affect seed germination and the establishment of strong and healthy seedlings under different environmental conditions. The aim of this work was to determine the effect of locality and production year on germination and vigor of soybean seed. The testing was performed on 6 soybean varieties (Valjevka, Bojana, Balkan, Novosađanka, Vojvođanka i Morava) produced in the towns of Inđija and Vrbas in 2009 and 2010. The seed germination of all samples was determined by using standard laboratory and vigor tests (Cold test and Accelerated aging test). When the standard laboratory test was applied the seed germination of all tested varieties produced in 2009 in Inđija ranged from 78% to 87%, and from 94% to 99% in Vrbas. The germination of seeds produced in 2010 in both localities was higher in all tested varieties in relation to 2009. When the accelerated aging test was applied the germination of seeds produced in Inđija in 2009 was statistically significantly lower (67-85%) in all tested varieties in comparison to seed germination obtained by the standard laboratory test (78-87%). The seed germination obtained by the application of the cold test was statistically significantly lower (25-90%) for the seed produced in Inđija in comparison to the value obtained for the seeds produced in Vrbas (80-97) for both years of production.

The testing of seed quality starts from the moment a sample is formed in a warehouse during processing or packaging of the seed. The seed sampling as the process of obtaining the working sample also assumes each step undertaken during its testing in the laboratory. With the aim of appropriate forming of a seed sample in the laboratory, the usage of seed divider is prescribed for large seeded species (such as seed the size of wheat or larger) (ISTA Rules, 1999). The aim of this paper was the comparison of different methods used for obtaining the working samples of maize and wheat seeds using conical, soil and centrifugal dividers. The number of seed of added admixtures confirmed the reliability of working samples formation. To each maize sample (1000 g) 10 seeds of the following admixtures were added: Zea mays L. (red pericarp), Hordeum vulgäre L., Triticum aestivum L., and Glycine max (L.) Merr. Two methods were used for formation of maze seed working sample. To wheat samples (1000 g) 10 seeds of each of the following species were added: Avena saliva (hulled seeds), Hordeum vulgäre L., Galium tricorne Stokes, and Polygonum lapatifolmm L. For formation of wheat seed working samples four methods were used. Optimum of 9, but not less than 7 seeds of admixture were due to be determined in the maize seed working sample, while for wheat, at least one seed of admixture was expected to be found in the working sample. The obtained results confirmed that the formation of the maize seed working samples was the most reliable when centrifugal divider, the first method was used (average of admixture - 9.37). From the observed admixtures the seed of Triticum aestivum L. was the most uniformly distributed, the first method also being used (6.93). The second method gains high average values satisfying the given criterion, but it should be used with previous homogenization of the sample being tested. The forming of wheat seed working samples is the most reliable if the fourth method is applied, regardless of which type of divider is used. The spoon method is unsatisfactory for the given criterion (average of admixture -0.77). The most uniform distribution of the admixtures in the wheat seed working sample, by all methods applied, was determined for Hordeum vulgare L. The presence of Polygonum lapatifohum L. was the most difficult to determine by the first (0.40), and the second (0.57) method. The most reliable method for wheat seed working sample formation was the method of conical divider. .

Common vetch (Vicia sativa L), hairy vetch (Vicia villosa Roth), and Pannonian vetch (Vicia pannonica Crantz) are the most often grown varieties in the production area of Serbia. The most important problem in the production of vetch seed is lodging. Yield and seed quality in lodged crops can be significantly reduced. Therefore, it is very important to accurately estimate the quality, and viability of produced seed. Common vetch, hairy vetch and Pannonian vetch were submitted to vigor testing using standard laboratory test, cold test, Hiltner test, and three variants of accelerated aging tests (39°C,72 h; 39°C, 96 h; 45°C, 48 h). When the standard laboratory test was applied, the common vetch achieved the highest seed germination value of 90%, while decreased rate of seed germination was due to unfavorable conditions applied in vigor tests. Above ground seedling growth parameters were the lowest when Hiltner test was applied. Length and mass of the root system were the lowest when accelerated aging test was applied. Hairy vetch obtained the lowest values for all tested parameters when Hiltner test was applied. Application of different variants of accelerated aging tests indicated that tested parameters were not dependent on the applied temperature, while reduction in legumes vigor was under the influence of temperature duration.

In order to determine the influence of genotype and mechanical damage during harvest on field pea seed quality, an examination has been carried out at the Experiment Field of the Institute of Field and Vegetable Crops and in the National Laboratory for Seed Testing. There were determined germination energy, germination, abnormal seedlings portion and 1000-seed weight in three field pea genotypes (NS-Junior, Jezero and Javor) in four harvest treatments (harvest by hand and mechanical harvest with 500, 650 and 800 o/min). The trial was established as a modified block system, with a randomised plot design and three replicates. Harvest has been carried out in the stage of physiological maturity, with a seed moisture of 13-14 %. After the harvest, seed was processed with a lab selector. Seed quality was tested by standard methods, according to the Guidelines on the seed quality of agricultural plants (Official Gazette of SFRY, No. 47/87) and ISTA Rules (1999), with a sample size of 1000 g. There were determined the following seed quality parametres: germination energy, germination, abnormal seedlings and 1000-seed weight. The lowest germination energy (79.82 %) and germination (84.94 %) were in the genotype with the largest seed size, Javor. This genotype had the largest portion of abnormal seedlings (11.39 %). Testa cracking before harvest was most prominent in the genotype Javor, that in harvest by hand had the lowest germination energy and germination (84.67 % and 89.67 %), as well as the largest abnormal seedlings portion (8.25 %). Testa cracking during seed filling and mechanical damage of testa in harvest were more prominent in teh genotypes with larger seeds. By this reason their seed has lower germination in comparison to the genotypes with smaller seeds. This is confirmed by a high siginificant negative correlation between germination and 1000-seed weight, r=-0.440**. [ABSTRACT FROM AUTHOR]

Wholegrain buckwheat and rye flours were used to partially replace wheat flour in honey biscuit formulation. Characteristics of dough and baked biscuits were studied. Buckwheat was the ingredient that dominantly affected the dough and biscuit quality. Doughs with buckwheat were significantly harder and less sticky. Significant lowering of dough cohesiveness was found only at the maximal tested buckwheat dose. The biscuits enriched with buckwheat had increased spread, hardness and fracturability. Rye showed an improving effect on dough (decreased hardness, increased cohesiveness) and biscuit characteristics (decreased spread, hardness and fracturability) but the effect did not reach significant level. However, no significant differences in sensory tests were obtained among the tested biscuits. Hence, buckwheat has a potential to be used as an ingredient in honey biscuit making to develop more nutritional end-product especially if adequate processing methods to improve its suitability in food applications are additionally considered.
