Abstract
Heterosis and combining ability in pigeonpea (cajanus cajan (L.) Millsp.) were studied in a set of 8 x 8 diallel crosses excluding reciprocals at Pulses Research Station, Gujarat Agricultural University, Model Farm, Baroda, during kharif season of the year 1984-85. Analysis of variance manifested highly significant differences for all the traits barring numbers of primary branches, indicating the presence of considerable genetic diversity in the experimental material studied. The magnitude of heterosis varied from cross to cross for almost all the traits under study. High values of heterosis were observed for the traits viz., pods per plant and seed yield, medium for clusters per plant and pods per cluster, while relatively low for rest of the traits.
