The experiment was laid out in Randomized Block Design with three replications following the recommended spacing of 45 cm X 20cm. The experiment was carried out to identify the genotype having higher yield, superior nutritional quality with least antinutritional quality and variations among the genotype. Analysis of variance revealed significant differences among the twenty-one genotypes. The highest yield per plant was recorded in CHF FaB-13 (126.98 g/plant) followed by CHF FaB-6 (97.09 g/plant) whereas maximum total soluble protein was recorded in CHF FaB-5 (32.21%) which was followed by CHF FaB-4 (31.93%) and CHF FaB-6 (31.57%) for seed and in cases of shell highest total soluble protein was recorded in CHF FaB-3 (18.76%) which was followed by CHF FaB-4 (15.54%) and CHF FaB-5 (14.78%).Genotypic and phenotypic coefficients of variance were found high for number of stems per plant (PCV= 40.93%, GCV= 37.13%) followed by yield per plant (PCV= 35.09%, GCV= 33.55%), vitamin C in seed (PCV= 49.07%, GCV= 48.98%), non-reducing sugar in shell (PCV= 45.19%, GCV= 43.96%). The characters recorded high heritability coupled with high genetic advance indicating these characters are governed by additive gene action. Correlation studies revealed that number of stems per plant, number of pods per plant, number of leaflet per leaf, pod length, pod width had positive and significant correlations with yield per plant whereas moisture content, total sugar and non-reducing sugar both for seed and shell had positive and significant correlations with total soluble protein both at genotypic and phenotypic levels. Number of pods per plant, number of stems per plant, plant height had direct positive effect on yield per plant whereas moisture content in seeds, total carbohydrates in seed, non-reducing sugar in seed, vitamin C in shell and reducing sugar in shell had positive direct effect on total soluble protein content. Highest yield per plant was recorded in CHF FaB-13 (126.98 g/plant), total soluble protein for seed and shell in CHF FaB-5 (32.21%) and CHF FaB-3 (18.76%) respectively. Highest content of L-dopa for leaves were recorded in CHF FaB-4 (4242.18 mg/100g), for flowers in CHF FaB-4 (3302.44 mg/100g), for seed in CHF FaB-9 (1909.76 mg/100g) and for shell in CHF FaB-7 (1701.22 mg/100g). Thus, these genotypes can be utilised for further improvement.EnglishThesis
