Abstract

The present communication reports the relative pollen fertility and morphology in interspecific crosses of pigeonpea. C. cajan x C. acutifolius hybrid showed low pollen fertility in F, generation, whereas high pollen fertility was found in crosses utilizing C. cajanifolius and C. scarabaeoides. Moderate variation (37.45 μm) was noticed in size of pollen grains among the parents and their hybrids. Cajanus acutifolius had the smallest pollen size.
