Abstract:

Twenty nine genotypes of Field bean (Lablab purpureus L.) were evaluated to study the genetic variability on yield, yield contributing and related 18 attributes viz.,, days to first flowering, days to 50 per cent flowering, days to first pod set, number of inflorescences per plant, length of inflorescence (cm), number of pods per inflorescence, length of the pod (cm), width of the pod (cm), days to first pod harvest, days to last pod harvest, weight of 10 green pods (g), number of pods per plant, number of seeds per pod, seed length (mm), seed width (mm), dry seed yield per plant (g), 100 seed weight (g) and fresh pod yield per plant. The range, genotypic and phenotypic coefficient of variation, heritability, genetic advance and correlation were calculated. The genotypes showed considerable amount of variability for all the traits. Wide range of variability was recorded for fresh pod yield per plant, dry seed yield per plant, days to 50 per cent flowering and days to first pod set. On the basis of mean performance, the genotypes, NAIP-BD-ADB-70 and NSJ-186 were found to be superior for almost all the attributes. The genotypic and phenotypic coefficients of variation were high (>20%) for fresh pod yield per plant, number of pods per plant and number of inflorescences per plant. The characters viz., number of pods per plant, days to last pod harvest, weight of 10 green pods, dry seed yield per plant and fresh pod yield per plant had high genetic high heritability coupled with high genetic advance and GA as per cent of mean indicating the predominance of additive gene action.
