Abstract
Considerable morphological differences were observed in reciprocal hybrids involving A. catechu and A.triandra. While A. catechu x A.triandra hybrids were intermediate for some characters, showed heterosis and dominance for certain other characters, and were highly sterile, A. triandra x A. catechu plants were almost similar to A. triandra and did not indicate any evidence of hybridity. Based on these and the failure of A. catechu pollen to germinate on stigmatic surface of A. triandra, the latter species is inferred to be apomictic. This is further supported by the occurrence of limited extent of meiotic irregularities, reduced pollen fertility, low quantity of pollen and nut set obtained without pollination. It has been inferred that apomixis in A.triandra is autonomous.
