摘要

Though pigeonpea is a self-pollinated crop, it exhibits up to 70% outcrossing (Saxena et al. 1990), varying with different locations. The yield levels in this crop have not been substantially enhanced mainly because the varietal improvement methods used have been those which are commonly used for the self-pollinated crops. New possibilities were opened with the discovery of stable genetic male sterility (Reddy et al. 1978) coupled with the reports of the presence of nonadditive genetic variation andsufficient heterosis for yield. This led to the release of two short-duration pigeonpea hybrids, ICPH 8 and COH 1.
