Heterosis was estimated over mid and better parent, respectively among 45 F1 hybrids for seed yield and related traits.. The mostdesirable cross combination viz., CR-1485 x CR-1607 for seed yield plant-1 also showed desirable mid and better parent heterosisfor 1000-seed weight and primary branches plant-1. The cross combinations CR-1485 x CR-1607 (primary branches plant-1), CR-1630 x KS-101 (secondary branches plant-1), CR-2638 x KOS-1 (number of siliquae on main raceme), CR-1630 x CR-2871(number of siliquae plant-1), CR-1607 x KOS-1 (days to maturity) and KOS-1 x KS-101 (oil content) showed highest mid andbetter parent heterosis. These cross combinations also revealed high per se performance.
