Abstract

Ten diverse cultivars of peas (Pisum sativum L.) were crossed in diallel and the parents, F_1s and F_2s evaluated for five quantitative characters. All traits studied except plant height showed considerable heterosis and inbreeding depression. Yield heterosis based on the mid-parent averaged 47 per cent and on the high parent 22 per cent. Both general and specific combining ability were important for all the traits studied; however, additive gene effects were predominant in the inheritance of these quantitative characters.
