Abstract:
The present investigation consists of 21 genotypes of Green gram including one check, which were grown in the Field Experimentation Centre of the Department of Genetics and Plant breeding, SHUATS, Prayagraj during kharif 2021 following RBD with three replications. The data were recorded on 13 characters to study the amount of genetic variability, heritability, association of yield contributing components with yield and direct and indirect effects of yield contributing component with yield and direct and indirect effects of yield contributing components in the Green gram genotypes. Based on the mean performance genotype CO-7 followed by were identified as best genotypes for seed yield per plant. High significant variation was obtained for all characters studies. High heritability estimates were observed for days to 50% flowering followed by days to 50% pod setting, number of cluster per plant, seed index, number of primary branches, seed yield per plant, number of pod per plant, number of seed per plant, plant height, harvest index, days to maturity, biological yield per plant. High values for heritability indicates that it may be due to higher contribution of genotypic components. High genetic advance as percent of mean was recorded high for harvest index, days to 50% flowering, days to 50% pod setting, plant height, number of pod per plant, seed index, number of cluster per plant, days to maturity, biological yield per plant, seed yield per plant, while moderate genetic gain is observed number of seed per pod followed by number of primary branches and pod length. Traits exhibiting high heritability coupled with genetic advance as percent of mean suggest that the traits are governed by additive gene action, equal contribution of additive and non-additive gene action respectively. The present study revealed that grain yield per plant was positively and significantly correlated with Harvest index. Path analysis at phenotypic level identified Harvest index, seed index, number of seed per pod, and number of pods per plantimportant direct components for seed yield per plant.
