Line x Tester analysis mean sum of square due to genotypes was highly significant for all the traits in E1, E2 and E3. Analysis of variance for combining ability revealed that the variance due to gca were highly significant for all the characters in all the environments except for days to maturity in E1, plant height and primary branches plant-1 in E1, E2 and E3, secondary branches, seed yield and harvest index in E2 and E3, pods plant-1 in E1 and E2, biological yield plant-1 in E2 and protein content in E1. Similarly variance due to sca were highly significant for all the characters in all the environments except days to maturity in E1, plat height, primary branches plant-1 and secondary branches plant-1 in E3, seed yield plant-1 in E2 indicated the importance of both additive and non-additive gene effect in their expression. Per se performance seed yield plant-1 is the ultimate and most important traits presented in table. In the present investigations, the degree of heterosis for seed yield varied considerably. Out of 21 crossed 2 crosses (JG 130 x JG 97 and JG 315 x JG 97) exhibited significant positive mid and better parents heterosis in all three environments. However, the highest mean value was sown JG 130 x JG 97(71.30 g plant-1) in E1, 66.55 g plant-1 in E2 and 40.55 g plant-1 in E3 for high seed yield should be utilized for future hybridization programme
