Abstract:

Genetic variability is the prime objective for crop improvement fraternity. Higher the amount of variation for a character greater will be the scope of its improvement through selection. Fifty six genotypes of greengram were evaluated in RBD for estimation of genetic variability, heritability, genetic advance, correlation coefficient and path coefficient analysis for yield and component traits. The genotypes showed wide and highly significant variation in all these traits. Seed yield of the genotype varied from 1.8 to 6.1 g/plant. PCV and GCV estimates were high for primary branches per plant. Plant height, pods per plant, days to 50% flowering, and maturity had high heritability with high genetic advance which indicated additive gene effect. Correlation studies indicated that plant height, clusters per plant, pods per plant, pod length, and 100 seed weight showed positive correlation with yield. Pods per plant had highest direct positive effect on yield followed by 100 seed weight.
