Abstract

Four lines were crossed with eleven testers in line x tester mating design for estimation of combining ability and heterosis for yield and its component characters in mustard (Brassica juncea). Lines PM-25 and PM-27 were found to be superior general combiners for length of siliqua and seed yield. PM-25 was also found to be a very good general combiner for number of seeds/siliqua and 1000 seed weight. The cross Varuna x Pusa Tarak showed high sca for seed yield followed by Varuna × Pusa LES-39 while for 1000 seed weight trait, Varuna x PM-28 and Varuna x PM-25 were found to be better. Varuna x Pusa Tarak also showed high sca for total number of siliqua/plant. Among the 44 hybrids, Varuna × Pusa LES-39 recorded highest heterosis for seed yield /plant over mid parent and better parent followed by Varuna × PM-27, Varuna × PM-26, Kranti× PM-27 and Varuna × Pusa Tarak. The results of this study suggest that the cross Varuna x Pusa Les 39 is best for high seed yield due to high siliqua length, number of siliqua at main axis, total number of siliqua/plant and number of seeds/siliqua.
