The experiment was established in the experimental field of the Small Grains Research Centre in Kragujevac during the two years. The winter wheat varieties used in the experiment was Takovčanka, Kruna, Toplica and Planeta. The following characteristics were analysed: grain yield, plant height, number of plants per m2, 1000 grain weight and test weight. The highest yield of all tested varieties of winter wheat was achieved by Takovčanka (4.124 t/ha). The highest plant height for all years was recorded for the cultivar Toplica (81.90 cm). The highest 1000 grain weight of investigation on winter wheat Takovčanka cultivar (44.05 g). The highest two-year average value of test weight was found in the cultivars Kruna and Planeta (71.03 kg/hl). Analysis of variance was found to have the highly significant effect of years in grain yield, plant height, 1000-grain weight and test weight and significant differences in number of plants per m2 at investigated wheat were found in relation to the year. &nbsp

Field trial with wheat varieties Perfekta, KG 56S, Aleksandra and Vizija was set on vertisol-type soil during the vegetation season 2010/11 and 2011/12. The aim of the research was to analyse the yield and grain yield components in four varieties of wheat cultivated on acid soil. The highest values of yield components and grain quality were established in the year with moderate temperatures and high precipitation in the vegetation year 2010/11. The KG 56S and Vizija varieties had the highest yield of grain, the highest number of plants and spikes per m2. The Perfekta variety showed the highest 1000 grain weight and grain weight per spike. The highest number of grains in the spike and the lowest average yield of grain during the research were recorded for the variety Aleksandra. A significant positive correlation between grain yield and grain weight per spike, the number of grains in the spike and the number of plants per m2 were established, as well as between the 1000 grain weight and the number of grains in the spike and the grain weight per spike. &nbsp

Poljski ogled sa sortama pšenice Takovčanka, Planeta, Kruna, Toplica i Vizija postavljen je na zemljištu tipa vertisol tokom vegetacionih sezona 2005/06-2011/12. godine. Cilj istraživanja je bio da se kod pet sorti pšenice gajenih na kiselom zemljištu analizira prinos zrna. Najveće vrednosti prinosa zrna ustanovljene su u godini sa umerenim temperaturama i velikom količinom padavina u vegetacionoj 2007/08. godini. Prosečan prinos zrna sorti pšenice kretao se od 3.743 t ha-1 do 6.275 t ha-1. Sorte Kruna, Planeta i Vizija imale su najveći prinos zrna. Na osnovu analize varijanse, moţe se zaključiti da postoje vrlo značajne razlike u prinosu zrna u odnosu na godinu ispitivanja, dok između ispitivanih sorti pšenice razlike nisu bile signifikantne. Field trial with wheat varieties Takovčanka, Planeta, Kruna, Toplica and Vizija was set on vertisol-type soil during the vegetation seasons 2005/06-2011/12. The aim of the research was to analyse the grain yield in five varieties of wheat cultivated on acid soil. The highest values of grain yield were established in the year with moderate temperatures and high precipitation in the vegetation year 2007/08. Average grain yield of wheat cultivars ranged from 3.743 t ha-1 to 6.275 t ha-1. The Kruna, Planeta and Vizija varieties had the highest yield of grain. Based on the analysis of variance, it can be concluded that there are very significant differences in grain yield regard the year of investigation, while among the investigated wheat cultivars the differences were not significant.

In this paper are presented results of winter hexaploid varieties of triticale (Kg 20, Favorit and Trijumf) from Kragujevac. Varieties are grown in the trial field of Small Grains Research Centre, Kragujevac during the season 2007-2008. The best parametar of productivity and grain quality for yield, grain weight and grain yield per plant is achieved by examined variety Favorit, while variety Trijumf had the best parametar for plant height. There is found a significant dependence of the examined components of productivity of genotype from the data analysis. It was found that genotype very significantly influence in grain yield and plant height between the varieties of triticale (P lt 0.01). Among the varieties of triticale showed no significant differences in grain weight and grain yield per plant. U radu su prikazani rezultati ispitivanja kragujevačkih ozimih heksaploidnih sorti tritikalea (Kg 20, Favorit i Trijumf). Sorte su gajene na oglednom polju Centra za strna žita, Kragujevac tokom 2007-2008 godine. Najbolji pokazatelj rodnosti i kvalitet zrna kod prinosa, mase zrna i prinosa zrna po biljci postigla je ispitivana sorta Favorit, a kod visine biljaka sorta Trijumf. Analizom dobijenih podataka utvrđena je značajna zavisnost ispitivanih komponenti kvaliteta zrna od genotipa. Ustanovljeno je da postoje vrlo značajne razlike u prinosu zrna i visini biljaka između ispitivanih sorti tritikalea (P lt 0,01). Između ispitivanih sorti tritikalea nisu ustanovljene signifikantne razlike za masu zrna i prinos zrna po biljci.

U radu je analizirano 40 genotipova ozimog dvoredog i višeredog ječma. Genotipovi su na osnovu tipa klasa podeljeni u dva ogleda. U prvom su dvoredi genotipovi i čine ga 12 priznatih sorti i 8 homozigotnih linija, a u drugom su višeredi genotipovi i sastoji se od 11 priznatih sorti i 9 homozigotnih linija. Ogledi su izvedeni na tri lokaliteta (Kragujevac, Zemun Polje, Zaječar) u dvogodišnjem periodu (2008/2009 i 2009/2010). Analizirane su sledeće osobine: visina stabla, dužina klasa, broj zrna po klasu, masa 1000 zrna, hektolitarska masa i prinos zrna. Primenom mešovitog modela kod oba tipa ječma i svih ispitivanih osobina utvrđena je visoka značajnost efekta genotipa i interakcije genotipa i spoljašnje sredine, dok efekat sredine nije bio statistički značajan. Sve razlike prosečnih vrednosti ispitivanih osobina između dvoredog i višeredog bile su značajne. Dvoredi su bili niži, veće dužine klasa, manjeg broja zrna po klasu, veće mase 1000 zrna, većeg hektolitra, većeg prinosa zrna. Na sva tri lokaliteta preporučuje se gajenje dvoredog ječma kao i sorte NS-525 koja je postigla visoke prinose u svakom od njih. Ocena interakcije genotip × spoljašnja sredina utvrđena je AMMI-1 modelom. Zapaženo je da kod prinosa nije postojala značajna razlika u broju stabilnih genotipova između dva tipa ječma iako su dvoredi bili prinosniji kao i da kod oba tipa ječma stabilni genotipovi imaju ispod i iznad prosečne vrednosti prinosa. Kod višeredog ječma linije su bile značajno prinosnije i stabilnije od sorti, dok kod dvoredog razlika nije uočena. Ranostasni genotipovi su kod višeredog bili stabilniji što ukazuje na veću tolerantnost dvoredog tipa ječma u odnosu na višeredi prema suši i visokim temperaturama koje se u našim uslovima često javljaju u toku nalivanja zrna. Ovim modelom izdvojene su i perspektivne linije koje se ističu po visini prinosa i stabilnosti. Kod dvoredog ječma to su linije J-176 i J-82, a kod višeredog J-33 i J-29... In this study, a set of forty genotypes of two and six-row barley was analyzed in two experiments based on the type of spike. The first experiment with two-row genotypes consisted of twelve cultivars and eight lines, while at the second one of six-row genotypes included eleven cultivars and nine lines. The experiments were conducted at three locations (Kragujevac, Zemun Polje, Zaječar) during two seasons (2008/2009 and 2009/2010). The following characters: stem height SH, length of spike LS, number of grains per spike NPS, 1000 grain weight TGW, test weight TW and grain yield GY were analyzed. By applying the mixed model in both types of barley and all investigated traits was determined by the high significance of the effect of genotype and the interaction of the genotype and environment, while the effect of the environment was not statistically significant. All of differences of average values at the studied characters between two groups were statistically significant. Two-row barleys were higher, spikes were longer, with less number of grains, as well as higher mass of 1000 grains, hectoliters and grain yields. Taking in consideration all three locations it is possible to recommend for cultivation tworow barley varieties and cultivar NS-525, since all of them achieved high grain yields. The genotype × environment interaction was analyzed by the AMMI-1 model (Method of Additive Main effects and Multiplicative Interaction). The graph shows that the yield was no significantly different in the number of stable genotypes between the two types of barley, although two-row were higher yielding and at both groups stable genotypes were below and above the average yield values. Six-row barley lines were significantly productive and stable than cultivars, while in a two-row group the difference wasn’t observed. Early-maturing six-row genotypes were stable indicating tolerance of two-row types in relation to six-row barleys, to since in our conditions drought and high temperatures, often occur during grain filling. This model allowed selection of promising lines by emphasizing the higher yield and stability simultaneously...
