Abstract

Information on the nature and degree of divergence is helpful in selecting the desirable parents for a breeding programme, since it is known that exploitation of heterosis and success in obtaining desirable recombinants is dependent on the degree of divergence of the parents [1]. Various reports were also accumulated that high heterosis is manifested in F1 hybrids whose parent possess high x low general combining ability (gca) effects [2]. Thus, the present investigation on genetic divergence and combining ability in relation to heterosis in Indian mustard [Brassica juncea (L.) Czern. and Coss.] for seed yield, its attributes and oil yield was taken up to give a clear-cut picture of whether the divergence studies through Mahalanobis' 02 statistics [3] are in agreement with the results of the analysis through diallel mating design by Griffing [4].
