Abstract
Highly significant differences were recorded among the treatments for all the characters. Analysis of variance further indicated highly significant differences among the parents, F₁s and parent vs. F₁s for all the characters. The estimated variance of general combining ability ( gca) were higher than variance of specific combining ability ( sca) for Days to flowering, days to maturity, plant height, number of siliquae per plant. The parents namely, Parent Urvashi and Maya are found good general combiners for seed yield per plant. The cross combinations Maya x Pusa Agrani and Jawahar mustard-1 x Urvashi are found good specific combiners for seed yield per plant. The cross combinations Maya x Durgamani, Maya x Urvashi, Jawahar Mustard-1 x Urvashi, Maya x Pusa Agrani, Maya x RLM-198, Durgamani x Urvashi, Urvashi x RLM-198 are exhibited positive and significant heterotic effects.
