The genetics of pod yield and yield traits in two crosses of okra namely KS 410 × HRB 55 and Varsa Uphar × Arka Anamika using North Carolina Design III was studied. A total of 72 biparental crosses were made in each crosses and 6 sets were formed by random selection of 12 progenies in each crosses. These progenies were evaluated in RBD with two replications during rainy and summer seasons of 1998. Results indicated the importance of both additive and dominance component for all the traits except girth of the pod and No. of branches/plant in the cross K-S-410 × HRB-55 in both the seasons. However, in the cross Varsa Uphar × Arka Anamika, only three traits namely pod weight, No. of pods/plant and pod yield/plant, showed importance of both the components of genetic variance. Yield and yield traits showed greater magnitude of most of the estimates in the rainy season as compared to summer seasons. Mean performance of various traits was also higher in rainy season. Average degree of dominance ranged from partial to complete dominance for most of the traits during both the seasons in both the crosses. Gene expression was better in rainy season than summer season. Therefore, it is advisable to practice selection in rainy season, which will be more effective.
