Chromosome Behaviour in Colchicine induced Autotetraploids of Cicer arietinum L

Abstract

Chromosome behaviour was studied in colchicine induced polyploids in their advanced generations. Polyploids were isolated as sterile, partial fertile and fertile tetraploids. The abnormalities like asynaptic behaviour, univalent formation, non-disjunction of chromosomes, unequal distribution at anaphasic separation, laggards and micronuclei were observed. Fertile plants showed a trend towards “bivalency” and were comparatively more productive.
