Heritabilities, correlations, and path coefficients for yield and yield related characters were estimated in the F2 generations of 30 possible combinations of six-parent diallel cross. The F2 populations were grown under two different plantings, early and late, in the experimental field of crop experimental field of Crops Experiment Station in 1984. The estimation of broad sense heritability was considerably high for the plant (71.0%), number of pods per plant (64.5%), 100-seed weight (94.9%), and seed yield (63.1%) and medium for the number of seeds per pod (26.8%). Seed yield was positively correlated with the number of pods per pla1312nt and 100-seed weight, and negatively with the plant height, the number of branches, and the first pod setting node. The days to flower was positively correlated with the plant height, the number of branches and the first pod setting node, and negatively with the number of pods per plant and 100-seed weight. Path analysis presented that the direct effect of the number of pods per plant and of 100-seed weight was predominant to seed yi
