Physical and chemical mutagenic effect on pollen fertility in M1 generation of Garden Bean [Lablab purpureus (L.) Sweet var. typicus cv. CO (Gb) 14]

S. Monica and N. Seetharaman

Mutation breeding has been widely used to develop a large number of desirable varieties in field and horticultural crops. The present study was performed by exposing the seeds with Gamma rays and Ethyl Methane Sulphonate to assess the pollen fertility in M₁ generation. It was observed, that the pollen fertility decreased with increasing dose/ concentrations of mutagens. The results showed that the treatment of EMS was more effective in reducing pollen fertility as compared to gamma rays and control. Pollen fertility percentage was better in control when compared to Gamma rays and EMS. Lower dose/ concentrations of these two mutagens produced less biological damage and would be suitable for inducing desirable attributes in Garden bean.
