Combining ability (gca and sca) and heterotic response analysis in Indian Mustard (Brassica juncea L. Czern and Coss) under Bundelkhand region

Combining ability analysis revealed that good general combiners were Urvashi x KMR-15-2, Pusa Agrani x Pusa Bahar, RH-749 x Pusa Bahar, RH-749 x Durgamani and KMR-15-2 x Pusa Bahar were best specific combiners for seed yield per plant. In hybrid high heterosis over better and mid parent Urvashi x KMR-15-2, Pusa Agrani x Durgamani, RH-749 x KMR-15-2, KMR-15-2 x Pusa Bahar and KMR-15-2 x Durgamani and Urvashi x KMR-15-2, Pusa Agrani x Pusa Bahar, RH-749 x Pusa Bahar, KMR-15-2 x Pusa Bahar and KMR-15-2 x Durgamani, respectively and high x high general combiners with significant sca effects for seed yield per plant. The parents namely, Urvashi, KMR-15-2, Pusa Agrani, Pusa Bahar, RH-749, Pusa Bahar, RH-749, Durgamani, KMR-15-2 and Pusa Bahar were good general combiners for number of traits and hence, may be used further in hybridization programme. Developmental attributes likes days to flowering, days to maturity, number of siliquae per plant and oil content, 1000-seed weight, seed yield per plant should be given maximum frequency for getting higher productivity in Indian mustard.
