Abstract: The present investigation was conducted at Vegetable Research Station, ARI, Rajendranagar, Hyderabad during August, 2016 to March, 2017. Thirty five genotypes were evaluated in Randomized Block Design with two replications evaluated for nineteen yield and yield contributing characters, which are diverse in origin. Correlation coefficient analysis revealed that Pod yield per plant exhibited positive significant correlation with vine length (0.511), number of pods per plant (0.494), pod weight (0.485), seed breadth (0.389), seed length (0.349), 100 dry seed weight (0.325), primary branches per plant (0.291), days to 50 percent flowering (0.254), days to first flowering (0.244) and pod length (0.240). Path analysis revealed that maximum positive direct effect on pod yield per plant was exhibited through pod weight (0.440) followed by protein content (0.235). Positive direct effect of primary branches per plant (0.229) on pod yield per plant was moderate. The direct negative effects on pod yield were observed by days to first flowering, days to last pod harvest and 100 dry seed weight.
