Selection of best germplasm & crosses based on heterotic response and combining ability parameters in Indian mustard ( Brassica juncea L. Czern & Coss)

Abstract

General combining ability effects revealed that the parents namely; Vaibhav, Varuna, Durgamani and Kranti were found good general combiners for seed yield per plant (g). Specific combining ability effects revealed that the crosses namely; Vaibhav x Mathura Rai, Pusa Jai Kisan x Pusa Agrani and KR-5610 x Pusa Agrani were found good specific combiners for seed yield per plant (g). High heterosis over economic parent (Varuna) was observed in the crosses namely; Rohini x Mathura Rai, Maya x RK-9807, Pusa Bahar x Pusa Agrani, KR-5610 x Pusa Agrani and Pusa Jai Kisan x Pusa Agrani for seed yield per plant. The above lines and cross combiners may be utilized to improve particular traits in Indian mustard.
