Abstract
An experiment was conducted at the International Crops Research Institute for the Semi Arid Tropics, Patancheru at Hyderabad to study the genetic variability, correlation and path analysis in BC1F 2 of (JL 24 X ICG 11337) X JL 24. High variability was observed for total number of pods per plant, mature seeds per plant, shelling per cent, hundred seed weight, LLS disease score at 75, 90 and 102 DAS and pod yield per plant. High PCV, GCV, heritability and genetic advance as per cent of the men was observed in mature pods per plant, mature seed per plant, immature seeds per plant, hundred seed weight, haulm weight per plant, LLS disease score at 75 DAS and pod yield plant. Whereas, moderate estimates of PCV and GCV with high heritability coupled with high genetic advance as per cent of mean for LLS disease score at 90 and 102 DAS. Low variability and genetic advance as per cent of mean was noticed for days to 50% flowering and days to maturity. In correlation coefficient study pod yield per plant was significantly and positively correlated with mature pods per plant, immature pods per plant, total pods per plant, mature seeds per plant, immature seeds per plant and haulm weight per plant, while it was negative non significant correlation with days to 50% flowering, days to maturity and shelling percent. Path analysis revealed that the maximum positive direct effect on pod yield per plant for mature seeds per plant, total pods per plant and hundred seed weight whereas, negative and maximum direct effect on yield was observed for mature pods per plant, immature pods per plant and shelling per cent.
