Abstract:

This study identified the best parents and hybrids on the basis of their general, specific combining ability and high heterotic performance for yield traits by Line x tester design. Results revealed that none of the parents showed significant GCA effect in the desired direction for all the traits. Pusa karishma was found to be the best general combiner for most of the traits, followed by PM-21 and varuna. The best three hybrids showing heterosis, and heterobeltiosis were PM-21 x RSPR-01, PM-21 x Varuna and Pusa karishma x kranti. The parents PM-21 (23.47) and varuna (22.60), respectively showed highest seed yield per plant. The crosses showing highest seed yield per plant were Pusa karishma x varuna (27.43) and PM-21× RSPR-01(22.47).
