Summary

A diallel cross involving ten varieties of sesamum was studied for heterosis and combining ability during 1975 at the J. N. Agricultural University, Jabalpur. In general, the magnitude of negative heterosis was higher than positive heterosis. Number of branches and number of capsules per plant were found to be the main contributing attributes for seed yield. ‘N66–173’ and ‘T.C. 66’ arc the best general combiners and ‘T.C. 66 × MS-l’ and ‘N66–173 × S.I. 1551’ showed high S.C.A. effects for yield.
