Abstract

Sixty four genotypes of Indian bean [Lablab purpureus (L.) Sweet] were evaluated for genetic variability and correlation coefficient analysis for green pod yield and its contributing characters. The analysis of variance revealed significant differences among the genotypes for all the traits. Plant height, seed yield per plant, seed yield q/ha, green pod yield per plant, green pod yield q/ha, pod width, weight of 10 pod, number of green pod per plant, pericarp thickness and days to first flowering exhibited high GCV and PCV values indicating large amount of variation. The highest heritability estimate was observed for days to last picking (99.60 %). In the present study highest value of EGA was observed for the seed yield per plant (194.78%) followed by the green pod yield per plant (175.87%). Green pod yield per plant exhibited positive and significant correlation with green pod yield q/ha, seed yield q/ha, plant height at 60 days, days to first flowering, days to first picking, days to last picking, weight of 10 pod, weight of 100 seed, number of green pod per plant, pod length, pericarp thickness, moisture percentage and seed yield per plant at both genotypic and phenotypic levels.
