ABSTRACT
The aim of this research was to create genetic diversity in plant height for two urdbean varieties namely T-9 and Pant U-30 by using gamma rays, ethylmethane sulphonate (EMS), and a combination of both treatments. The outcomes revealed that the average plant height values shifted towards negative direction in both M2 and M3 generations. Additionally, the genotypic coefficient of variation, heritability, and genetic advance showed a significant increase in the treated population. The treatments involving moderate doses of gamma rays (200 Gy and 300 Gy), EMS (0.2% and 0.3%), and combined gamma rays + EMS (200 Gy+0.2% and 300 Gy+0.2%) were found to be more effective and efficient in generating polygenic variabilityfor plant height. The findings suggest that these treatments could be utilized to obtain urdbean mutants with desirable traits such as shorter stature, resistance to lodging, and higher yield.
