Abstract:
The present study was conducted to assess the general combining ability effects of parents and specific combining ability effects of crosses for yield and yield related traits. 42 F1s developed by line x tester were evaluated. The ratio of sca/gca variance revealed that there was preponderance of additive gene action in the expression of yield and yield contributing characters. The maximum GCA effects were exhibited by parent DBW-179 for grain yield per plant (3.83) and harvest index (8.33) in late sown environment. The maximum SCA effects (3.20) were depicted by cross KBRL 82-2 x RAJ 4079 in late sown environment for this trait.
