The miotic and meotic behaviour is considered to be one of the most dependable indices to estimate the potency of mutagen cytological aberrations in plants serve as an excellent monitoring system for the determination of mutagens that may cause a genetic hazard in the present study cluster bean contains 7 bivalents (24 = 14) for the present investigation the plant exposed to dolf concentration of 60, 80, and 100kr gamma rays and 0.4, 0.6 and 0.8 % Mm ( EMS ) the present study reveals various chromosomal aberration includes stickiness precocisus movement ,single and anaphasis bridge laggards and synchronized movement of chromosomes at anaphase.
