Abstract
The present study deals with the cytological abnormalities induced by gamma rays, EMS and their combination in sesame (Sesamum indicum L.) var.TMV3. The seeds of sesame var.TMV3 were treated with different doses of gamma rays (30, 40, 50, 60 and 70KR), various concentrations of EMS (0.6, 0.8, 1.0, 1.2 and 1.4mM) and their combinations (30KR+0.6mM, 40KR+0.8mM, 50KR+1.0mM, 60KR+1.2mM and 70KR+1.4mM). Through root tip squash technique and mitotic studies, various cytological abnormalities induced by different mutagens and treatments as said above were studied in the crop used. The results showed the dose dependent influence in the induction of chromosomal/ cytological abnormalities and it was more pronounced as the doses /concentrations of mutagens increased. The main chromosomal aberrations like stickiness, precocious movements, laggards, bridges and ring chromosomes were observed. Though the abnormalities increased with increasing dose...
