This study aimed to determine the effect of composition of growing media and types of fertilization on the growth and production of mustard plants. This study was carried out at the Experimental Garden of Uniprima-Sengkang from February to April 2020, using a randomized block design with two treatment factors, namely the growing media consisting of soil (control), manure + soil (1: 1), bokashi + soil ( 1: 1), and soil + manure + Bokashi (1:1:1) and fertilization, namely: without urea and Azotobacter, urea 50 kg ha1 (0.2 g/plant), Azotobacter, urea 50 kg ha-1 (0.1 g/plant+ Azotobacter). The results showed that the composition of the growing medium Soil + Manure + Bokashi (1:1:1) and fertilization with ½ Urea 50 kg ha-1 (0.1 g/plant) + Azotobacter tended to show higher result in the parameters of plant height, number of leaves, leaf width and plant weight than other treatments, however, it statistically showed no interaction between the composition of the growing media and fertilization

Soybean is an important food crop after rice and maize. Soybean production in East Kalimantan based on the estimated 2014 rate is estimated at 1,263 tons of dry seeds. Compared to 2013 production there was a decrease of 139 tons (9.91%) (BPS, 2014). The low productivity is because soybean cultivation is still not optimal. One of the cultivation that can be done is by using Fish Waste and Solid POC. The purpose of this study was to determine the growth response of soybean (Glycine max l. Merril) by giving poc fish waste and solids. This research was conducted in Sidorejo Hamlet, Bilah Hilir District, Labuhan Batu Regency, North Sumatra Province. The research method used was factorial randomized block design (RBD) consisting of 2 factors, 9 combinations and 3 replications. The first factor was the provision of POC fish waste (P) consisting of 3 levels, namely: P0 = 0 ml / planting hole, P1 = 100 ml / planting hole, P2 = 200 ml / planting hole. The second factor is the provision of solid (S) consisting of 3 levels, namely: S0 = 0 ml / planting hole, S1: 100 ml / planting hole, S2: 200 ml / planting hole. Parameters observed were plant height, number of leaves, leaf width and stem diameter. Based on the results of research in the field, it shows that the provision of fish waste poc and solid has no significant effect on all observed parameters. Meanwhile, the interaction between poc and solid fish waste also had no significant effect on all observed parameters. Keywords: Soybean, POC Fish Waste, and Solid

The generation of morphological traits of plants such as the leaf length, width, perimeter, area, and petiole length are fundamental features of herbarium specimens, thus providing high-quality data to investigate plant responses to ongoing climatic change and plant history evolution. However, the existing measurement methods are primarily associated with manual analysis, which is labor-intensive and inefficient. This paper proposes a deep learning-based approach, called Deep Leaf, for detecting and pixel-wise segmentation of leaves based on the improved state-of-the-art instance segmentation approach, Mask Region Convolutional Neural Network (Mask R-CNN). Deep Leaf can accurately detect each leaf in the herbarium specimen and measure the associated morphological traits. The experimental results indicate that our automated approach can segment the leaves of different families. Compared to manual measurement done by ecologist and botanist experts, the average relative error of leaf length is 4.6%, while the average relative error of leaf width is 5.7%.

Purple cabbage plants require an adequate supply of water in the process of growing. So that if there is a lack of water it can result in stressful conditions then the growth of purple cabbage is disrupted and can even cause death. The purpose of this study was to determine the tolerance limits of purple cabbage to PEG 6000, and to determine the effect of PEG 6000 on the growth of purple cabbage as a simulation of drought stress. This research was conducted using a completely randomized design with the main factor being PEG 6000 with 5 concentration levels: 0 % w/v, 10% w/v, 20% w/v, 30% w/v and 40% w/v with 5 replications. As parameters are plant height, length, width, and number of leaves, also chlorophyll content. Then analyzed with the Levene test, one way ANOVA and the Tukey HSD test at 5% level. Based on the results of the research, it can be concluded that giving PEG 6000 shows that the tolerance limit for purple cabbage plants to PEG 6000 treatment is at a concentration of 10%, then giving PEG 6000 gives a negative response to the growth of purple cabbage which is indicated by a decrease in plant height, leaf length, leaf width, number of leaf, also chlorophyll a, b, and total chlorophyll content.

Leaf area measurement is pivotal for plant physiologists. Hence, accurate measurement of their leaf area is incredibly relevant in agronomic terms. The plant Stevia rebaudiana is a sucrose-free plant species that is now vital to the global production of sucrose-free foods. Here, we estimated S. rebaudiana leaf area using a nondestructive methodology comprising allometric equations. Through leaf length (L), leaf width (W), and/or their product (LW) the leaf area was determined. One thousand leaves were sampled from four distinct S. rebaudiana genotypes for model construction. Linear or power models were generated, and the best equation was selected using a statistical criterion. The statistical criteria indicated that the linear models best suited all genotypes tested, included a function of LW, exhibited increased stability, and precisely estimated coefficients. ANOVA revealed that both generalized and combined equations were feasible. Nevertheless, grouping all genotypes into a single model was not possible as the genotype leaf architectures were very dissimilar.

Maize leaf length, leaf width, leaf angle, and leaf orientation value are determinant traits influencing leaf shape, yield potential, and can sense water stress signals. However, little is known regarding their genetic controls under drought stress. Using two F3 populations, we identified 72 QTLs under contrasting environments at V18 and R1 stages by single-environment mapping, 58.3% QTLs were identified under drought-stressed environments. Thirty-three joint QTLs were detected by joint analysis of all environments, 7 QTLs involved in QTL-by-environment interactions, 11 pair epistasis exhibited additive-by-additive effects. Twelve constitutive QTLs were dissected that will be potentially useful for genetic improvement of maize leaf development through QTL pyramiding. Additionally, 13 meta-QTLs were identified via meta-analysis, 15 candidate genes were identified in these meta-QTLs. These results provide valuable information for QTLs fine mapping, revealing genetic mechanisms of leaf shape under contrasting watering environments, and alleles provide useful targets for marker-assisted selection breeding.

Bundelkhand region is rich in biodiversity for wood apple but less harnessed. The agro-climatic conditions of Bundelkhand have great potential for its commercial cultivation. Keeping these points in view, twenty-five genotypes of wood apple, fruit sample with shoot were collected from diverse areas of Bundelkhand region of utter Pradesh and analysed for various physic-chemical attributes and results of study revealed wide range of variability in morphological quantitative qualitative and biochemical etc. The quantitative variability of different genotypes in wood apple viz for fruit length (4.22 cm to 7.46 cm), fruit width (3.06 cm to 6.41 cm), shell thickness (0.10 cm to 0.31 cm), fruit weight (65.9 g to 238.7 g), leaf length (2 cm to 4.3 cm), leaf width (.97 cm to 2.3 cm), seed length (4.7 mm to 8.0 mm), seed width (2.97 mm to 4.77 mm), seed weight (23.76 g to 30.4 g), and No. of seed per fruit (102 to 614).

The objective of this study was to determine the agronomic diversity of gamma-ray at 50 Gray dose during the phase of embryogenetic callus in napier grass cv Taiwan. This research used a randomized blok design (RBD) of gamma-ray and without radiation elephant grasses (P. purpureum cv Taiwan). There were 51 numbers in irradiated elephant grass, each number three replicated and five plant per number each. Without irradiation control used elephant grass (P. purpureum cv Taiwan); there were 10 clumps in one block and each line number had been repeated three times. Gamma radiation showed no impact on plant height and stem weight (dry weight) at P>0.05, but had a significant effect on number of tillers, leaf length, leaf width, total weight, fresh weight, leaf (dry weight), weight of stem (fresh weight). Gamma ray irradiation selection does not have to generate high output but can be developed on sub optimal soil or extreme weather conditions such as tolerant felling, which requires less high plant. Key words: diversity, forage, irradiation

This study was carried out to investigate the effect of the LED light source on the growth and flowering characteristics in potted chrysanthemum ‘Orange Egg’ during cultivation in a closed growth chamber with a constant temperature of 22℃ and a photoperiod consisted of 11 hours light and 13 hours darkness. Each LED light source of blue (444 nm), red (652 nm), or mixed LED (blue:red:white=2:5:1) was supplied separately. As a result, the plant height of the pot-mum 'Orange Egg' grown in red LED was longest with an average of 9.43 cm. And the plant height in blue LED was shorter than in mixed LED, but there was not statistically significant between them. The plant width and leaf width were also largest in plants grown under red LED similar to the growth response of the plant height. But the number of leaves and leaf lengths were more and longer in monochromatic LED such as blue or red than mixed LED. Flower bud differentiation was completed around 16 to 17 days after short-day treatment regardless of LED light source. However, pot-mum plants grown in red and blue LED did not develop flower buds normally and reach final flowering although those grown in mixed LED were fully flowered around 5 weeks after short-day treatment. Therefore, it is considered that the mixed LED consisting of blue, red and white is useful as LED light source for producing potted chrysanthemums in plant factories.

—Daustinia montana (Convolvulaceae) is the only species of the genus, and is notable for its wide leaf variability. To understand whether this plasticity is correlated with the distribution of the species, linear morphometric and leaf contour analyses were performed. Specimens from herbaria were photographed, and pre-established linear measurements were made. A multivariate analysis was then performed to test the strength of associations among morphological characteristics, climatic variables, and distribution of the species. Elliptic Fourier analysis based on 20 harmonics was used to generate shape descriptors, resulting in nine main components. With elliptic Fourier descriptors, a grouping tree was created that suggests the existence of six morphotypes in D. montana. Moreover, clustering analysis revealed two large groups distinguished mainly by leaf width. The present findings indicate that the morphotypes are strongly related to latitude and that other characteristics such as the type of indumentum are related to climatic variables.

Mutated genetic resources play a crucial role and are of utmost importance in gene/allele characterization. Currently, hexaploid wheat mutated resources are rarely available. In the present investigation, a mutated population comprising 1,536 EMS-induced mutation lines (M7 generation) of bread wheat (Triticum aestivum L.) were used as an experimental material. Mutant population was developed and maintained at G.B.P.U.A.T, Pantnagar. The experiment was conducted in augmented block design II. in season 2019-20 at Norman E. Borlaug Crop Research Centre G.B.P.U.A.T, Pantnagar. The study revealed that number of tillers per plant recorded significantly higher direct effect on grain yield per plant followed by number of grains per spike, thousand grain weight, plant height, ear length, flag leaf width, grain length, flag leaf area and number of spikelet per spike. The association between grain yield per plant and these characters was significant. The direct negative effects on grain yield was observed by grain width, flag leaf length and peduncle length.

Estimation of leaf area by using leaf length and leaf width variables could be done without destruction of the leaves from plants and more practical than using the leaf areameter. Surface area is a function of the variable length and width, so the leaf area can be measured based on leaf length and leaf width variables. The purpose of this research is to get the leaf area estimator model with nondestructive method. Taro plants were observed by using 12 accessions/varieties taken from the germplasm collection in Gene Bank Collection of ICABIOGRAD, IAARD. Observations of the length, width, and area of leaf were carried out on 10-12 leaf samples for each accession/variety from taro cultivation which was about 4 months old. The length (P), width (L), and area (Y) of each taro leaf were measured. The estimation of taro leaves area by regression equation was analyzed by using one (P or L) and two (P and L) independent variables. Estimation using two variables, leaf length and width, is better than only use one variable. Taro leaf area (Y) of each leaf can be determined by the equation Y = 0.9462 P x L for ratio of P/L less than 1.10, Y = 0.9109 P x L for ratio of P/L between 1.10-1.19, and Y = 0.8860 P x L for ratio of P/L equal or greater than 1.20. Keywords: model estimation, leaf area, taro

Present study was investigate the effect of different UV-doses on morphological defending system features of two palm species Phoenix dactylifera L. and Washingtonia filifera (Lindl.) H. Wendl. The results showed that the morphological and biomass traits of both palm species grown for 30 days under UV-B with a rate of 2 hrs.day-1 were almost improved. Where, the highest leaf width was recorded (1.1 and 0.7 cm) respectively. Conversely, UV-treatment (4-10 hrs.day-1) has adversely affected on almost morphological and biomass features of both species. Where, the less leaf widths were recorded 0.95, 0.8, 0.73, 0.45, 0.43 and 0.40 cm in both palm species. Besides, results also spotted changes in leaf’s surface appearances. However, present investigation concluded that morphological features and biomass of both species were unaffected with low dose of UV-radiation (2 hrs.day-1). But, date palm (P. dactylifera L.) was capable to survive at high dose of radiation conditions reaches 8 hrs.day-1 for 30 days.

The study investigated the emergence and early seedling development of Monodora myristica in six different growth media viz: mixture of river sand/top soil, river sand/saw dust, top soil/saw dust, saw dust only, top soil only and river sand only. Results obtained recorded highest percentage germination (63%) in seeds sown in saw dust only. Early seedling growth was observed for four months. The results of this study showed that seedlings sown in mixture of top soil/saw dust recorded highest mean plant height (16.83cm), stem girth ( 2.50mm), and leaf area (46.18cm2) at the end of the experimental time. Seedlings on top soil only had the highest number of leaves (3.89). River sand had the least seedling performance in all the growth parameters examined; plant height (13.27cm), stem collar girth (1.99mm), leaf length (8.61cm), leaf width (4.77cm) and leaf area (30.83cm2). The study established that the % emergence of Monodora myristica seedlings was best in saw dust medium while mixture of top soil/saw dusts is recommended for enhancing early seedling growth of this plant in the nursery.

Acclimatization is one of the important processes in banana micro propagation before plantlets/planting materials are ready to be cultivated in the field. Trichoderma sp. are well known as plant promoter fungi that can promote plant growth and increase survival rate of plantlets. The study was arranged in a Completely Randomized Factorial Design with two factors and four replications. The first factors was covering type i.e. 1) individual covering and 2) mass covering. The second factor was the proportion of Trichoderma addition into manure, namely A) manure without the addition of Trichoderma sp. (control), B) Trichoderma sp. : manure = 1 : 400 (w/w), C) Trichoderma sp. : manure = 1 : 800 (w/w) and D) Trichoderma sp. : manure = 1 : 1,200 (w/w). The purpose of this study was to investigate the effect of Trichoderma sp. applications and covering types in the growth of banana plantlets cv. Barangan during the acclimatization process. The results showed that the best treatment to induce plantlet growth during the acclimatization process was the addition of Trichoderma sp.: manure with 1 : 400 (w/w) proportion and individual covering. The combination of Trichoderma sp. : manure with 1 : 400 (w/w) proportion and individual covering produced plant height and leaf length 8.5 cm and 4.4 cm, respectively, compared to the treatment without Trichoderma sp. addition that produced plantlets with 6.6 cm height and 3.4 cm leaf length. No significant interaction was shown between Trichoderma sp. proportions and covering types on leaf width, the number of leaves and root length parameters.

Shoot morphology in rice plants changes in response to P deficiency. However, how genotypic variations in these morphological changes affect the canopy development and biomass production have hardly been explored. The study aimed to identify specific shoot morphological traits that confer biomass production under P deficiency. Four rice genotypes, including AZ-97 (WAS 63���22-5-9-10-1), which exhibits high performance under highly P-deficient fields in Madagascar, were grown for 56 days in flooded pots over several P application rates to simulate P-sufficient and moderately, severely, and extremely P-deficient conditions. AZ-97 had superior shoot P contents and biomass than Takanari, a high-yielding cultivar, and X265, a common high-yielding cultivar in Madagascar at severely to moderately P-deficient conditions. Shoot biomass was highly correlated with projected leaf area (PLA) from the early growth stage, and tiller number, leaf width, and leaf elongation rate explained the variations in PLA. These morphological traits reduced significantly with decreased P application rates, while reduction in AZ-97 was small relative to the other genotypes, even for equivalent shoot P contents. As the result, AZ-97 had greater PLA per unit of shoot P content at equivalent shoot P contents. The result indicates that lower sensitivity and degrees of change in shoot morphology when exposed to P deficiency stress could be a key trait facilitating the maintenance of captured radiation and subsequently influencing genotypic differences in external P uptakes and biomass production. AZ-97 is a potential donor with such traits that can offer an additional avenue for genetic improvement toward P-efficient rice production.Abbreviations DAT: days after transplanting; LN: leaf number in the main stem; PLA: projected green leaf area; PUE: phosphorus use efficiency; SSA: Sub-Saharan Africa.

Seagrass has long been known to be very sensitive to environmental changes, especially caused by human activities (anthropogenic disturbance) and has been used as a bioindicator for environmental condition. This research aimed to study interaction of Thalassia hemprichii measured and derived variables (metrics), at two locations i.e., inhabited island (high anthropogenic location) and uninhabited island (low anthropogenic location). Confirmative approach was conducted using a developed conceptual model based on preliminary studies, the conceptual model was analyzed in multivariate context using data from field observation. The result showed that Thalassia hemprichii dominated and have higher above ground biomass value in inhabited area which indicated high nutrient input, meanwhile uninhabited area showed a higher below ground biomass value. Above ground of Thalassia hemprichii that have direct effect on its biomass and below ground metrics was leaf width, meanwhile leaf length of Thalassia hemprichii have indirect effect on its biomass and below ground metrics. The result also indicated some different metric covariations which were influenced by the degree of Thalassia hemprichii density. Leaf length, leaf width, density, and percent cover of Thalassia hemprichii potentially could be used as components in multimetric index and bioindicator for environmental quality.

Selection parameter in coffee breeding for leaf rust (Hemeleia vastatrix) resistance is very important. Breeders used leaf-rust severity and leaf-rust incidence as parameters of direct selection. However, scientific proof is not yet available whether leaf morphology can be used as a parameter of indirect selection. The objective of this research was to seek the possibility of leaf morphology parameter and its ratio to be used as selection criteria through analyses of genotypic and phenotypic correlations of parameter of rust disease and parameter of leaf morphology and its ratio. The result revealed that genotypes showed significant variations in leaf-rust severity (5.21–25.84%), leaf morphology, and leaf-morphology ratio. Leaf length to leaf width ratio, leaf length to leaf area ratio, and leaf width to leaf weight ratio were not affected by the environment. Leaf-rust severity performed highly significant positive genotypic and phenotypic correlations the ratio of with leaf length to leaf area. For selection criteria, leaf-rust severity could be better used rather than leaf-rust incidence and branch-rust incidence. The ratio of leaf length to leaf area could also be used as an indirect selection criterion because the ratio showed a highly significant genotypic correlation with leaf-rust severity (rGab = 0.254**). However, the ratio of leaf length to leaf area is even better chosen for selection criteria rather than leaf-rust severity because the ratio was not affected by the environment.

Potato (Solanum tuberosum L.) is one of crops which cultivated by farmers in Central Sulawesi. These potatoes are traditionally cultivated without going through the breeding process, so they have high variations. This study aims to obtain information on genetic diversity, heritability, and correlation between the characterics of potatoes from farmers in Napu who are still cultivating potato crops. Design used in this study was a randomized block design with two replications. The results showed that tuber color and harvest age had a small coefficient of genetic diversity. The heritability values ​​of tuber color are include in the small category, Diameter of stem, number of leaves, leaf length, leaf width, leaf color, tuber length, tuber diameter, tuber weight, number of tuber and harvest age in this study are include in the high category. So that, these characteristics can be derived and selection can be made. In Napu potatoes, the number of tubers was genetically positively (medium) correlated between plant height and stem diameters, plant height with leaf width, leaf length with leaf width, leaf length with tuber diameters and tuber diameters with the number of tubers. While the positive correlation was very significant (strong) between plant height and leaf length, and very significant (strong) negative correlation between leaf color and tuber length, so can be used as a selection criteria for increasing potato crops.

Sesamum indicum ‘Baekseol’ plug seedlings were treated with the fungicide diniconazole as a growth retardant in comparison to paclobutrazole. Seeds were sown in 128-cell plug trays. Paclobutrazole (0, 15, 30, and 60 mg L−1) and diniconazole (100, 200, 300, and 400 mg L−1) were foliage sprayed when first leaves were developed. Stem growth was similar between paclobutrazole and the control, but strongly retarded by increasing concentrations of diniconazole. Leaf numbers did not differ in all treatments. As the diniconazole concentration increased, leaves became thicker, while leaf width and length decreased. In diniconazole treatment, shoot fresh weight decreased, but root fresh weight increased. Therefore, the T/R ratio was lowered by diniconazole treatment. After transplanting, the taking roots of paclobutrazol-treated plants were below average (

In barley (Hordeum vulgare L.), lateral branches called tillers contribute to grain yield and define shoot architecture, but genetic control of tiller number and developmental rate are not well characterized. The primary objectives of this work were to examine relationships between tiller number and other agronomic and morphological traits and identify natural genetic variation associated with tiller number and rate, and related traits. We grew 768 lines from the USDA National Small Grain Collection in the field and collected data over two years for tiller number and rate, and agronomic and morphological traits. Our results confirmed that spike row-type and days to heading are correlated with tiller number, and as much as 28% of tiller number variance was associated with these traits. In addition, negative correlations between tiller number and leaf width and stem diameter were observed, indicating trade-offs between tiller development and other vegetative growth. Thirty-three quantitative trait loci (QTL) were associated with tiller number or rate. Of these, 40% overlapped QTL associated with days to heading and 22% overlapped QTL associated with spike row-type, further supporting that tiller development is associated with these traits. Some QTL associated with tiller number or rate, including the major QTL on chromosome 3H, were not associated with other traits, suggesting that some QTL may be directly related to rate of tiller development or axillary bud number. These results enhance our knowledge of the genetic control of tiller development in barley, which is important for optimizing tiller number and rate for yield improvement.

An experiment was conducted to find out the effects of some pre-germination seed treatments on germination of mango (Mangifera indica L.) seeds and initial growth of mango. Seeds obtained from a local mango variety at Nyankpala were sown in polyethylene bags filled with topsoil for the experiment. The four treatments used were; seeds sown without seed coats (SW), seeds without seed coats soaked in cool water of 5ºC for 12 hours before sowing (SSC), seeds without seed coats soaked in warm water of 15ºC for one minute before sowing (SSW) and seeds with seed coats sown to serve as the control (SC). Randomized Complete Block Design was used and each treatment was replicated three times. The parameters measured were germination percentage, height of seedlings, leaf length of seedlings, number of leaves and stem diameter of seedlings. Data obtained were analyzed using Analysis of Variance and the differences were determined by using Tukey-Kramer multiple comparison test. All the treated seeds recorded more than 80% of germination three weeks after sowing, with SSW recording the highest value of 91%. In general, the treated seeds performed significantly (p < 0.05) better than the control for the parameters studied. SSW is recommended for adoption since it performed optimally better than the other treatments in terms of number of leaves (7.67), leaf length (14.71 cm), leaf width (4.41 cm), stem diameter (1.82 cm) and plant height 20.86 cm).

This study aimed to determine the morphological and cytogenetic differences in an intraspecific Asiatic F1Lilium hybrid. The results indicated that leaf color and shape, flower morphology including color, spot size on petal, and filament color in the F1 hybrid showed significant variations as compared to parents, while days to flowering were similar to those of the parents. Moreover, stem height, leaf number, and leaf width showed distinct variations. Interestingly, the intraspecific F1 progeny obtained from Asiatic lily parents showed higher pollen viability. In addition, FISH results revealed significant variation in the number of 18S rDNA and 5S rDNA loci identified in both parents and the F1 progeny. The female (2n = 4x = 48) parent had 12 loci of 18S rDNA, whereas the male (2n = 2x = 24) parent and the F1 (2n = 3x = 36) had 8 and 11 loci of 18S rDNA, respectively. Moreover, the F1 progeny had 9 loci of 5S rDNA compared with the 7 and 4 loci identified in the female and male parents, respectively. All 5S rDNA signals were observed on the long arm in both the female parent and the F1; however, one 5S rDNA signal was observed on the short arm in the male parent. Therefore, this study demonstrated that the distribution of ribosomal DNA was greatly different in the F1 progeny than that of parents.

Chili high yield is the target of plant breeding. High yielding chili selection can be done through direct selection of yield characters and indirectly through other characters. Indirect selection is more efficient than the selection of one character. This research aims to study the relationship between quantitative characters with yield as well as obtaining the selection criteria. Correlation analysis results showed that the fruit weight, fruit diameter, pericarp thickness, leaf width, and leaf length were positively correlated and were very significant on yield. Based on the path analysis, characters that have a positive direct effect on yield are fruit weight, fruit diameter, leaf width, and leaf length, while pericarp thickness had a negative direct effect but had a large indirect effect on yield.

A field trial was conducted to weigh up the path coefficient analysis between various morphological traits which directly as well as indirectly associated with yield of various bottle gourd genotypes. The research experiment consists of total 37 genotypes conducted at Research Farm of Vegetable Science department, Chaudhary Charan Singh Haryana Agricultural University, Hisar during summer season. Genotypes were sown with three replications following (RBD) randomized block design. The observed data were taken for further statistical analysis. Substantial amount of variability was found for the sixteen morphological traits which were confirmed by the ANOVA (analysis of variance). The characters having positive direct effect on yield per ha are number of primary branches, leaf width, nodes to first female flower, days to first female flower opening, days to fruit harvest, number of fruits per vine, fruit yield per plant and weight of seeds.
