Gamma Radiation Induced Chromosomal Aberrations at Mitosis in Allium cepa L.

Ramesh Ahirwar

Abstract: Mutagenic effectiveness of gamma rays on Allium cepa was studied. The seeds were treated with five doses (viz.5kR, 10kR, 15 kR, 20kR and 25kR) of gamma rays. Chromosomal abnormalities were observed. Chromosomal aberrations like, dicentric, tricentric, ring, minute, deletion, fragment, laggard, bridge and micronuclei were noticed in treated root tip mitosis. The chromosomal abnormalities were increased with increasing doses. The chromosomal abnormalities were dependent on the radiation doses.
