Abstract

An experiment was carried out to study the anther dimorphism and meiotic behavior of chromosomes in different morphs of anthers in Crotolaria spectabilis. Anthers exhibit dimorphism with respect of their shape, size, surface ornamentation, dehiscence time, pollen size, pollen sterility, pollen germination and meiotic behavior of chromosomes. Meiotic indices, percentage share of different meiotic stages, chiasma frequency per pollen mother cell, chiasma frequency per chromosome, and percentage share of different meiotic anomalies varied with type of anther.

Key words: anther dimorphism, Crotolaria spectabilis, heteroanthery, meiotic anomalies.
