ABSTRACT
The study of the effect of three well known mutagens, ethyl methane sulphonate (EMS), methyl methane
sulphonate (MMS) and gamma rays (GR) on the yield contributing traits of the urdbean variety TPU-4 were carried out in
the M3 generation. Effect of selected mutagenic treatments/doses of EMS (0.02, 0.03 and 0.04 M), MMS (0.0025, 0.05
and 0.01 M) and (GR) (30, 40 and 50 KR) on different yield contributing traits like plant height, plant spread, number of
pods per plant, pod length, number of seeds per pod, seed yield per plant and 100 seed weight were analyzed in the M3
populations of the variety TPU-4. Seeds of M2 plants and control were harvested separately and sown to raise M3
population.. Genetic variabilty in the mutagen administered M3 progeny of the urdbean variety TPU-4 was analyzed by
employing statistical methods. Data on mean values and shift in the mean of seven quantitative traits was evaluated on
individual plant basis. The experimental findings revealed that concentrations / dose of the all these mutagens showed
inhibitory effect on plant height, number of pods per plant, pod length and number of seeds per pod. Lower concentrations
of mutagens exerted a promotory effect on plant spread, 100 seed weight and seed yield per plant while higher
concentrations of these mutagens inhibited them to different extent.
Key words : EMS, GR, MMS, Mutations, Urdbean, Yield contributing traits.
