Abstract

Urdbean is an important pulse crop produced in all seasons but due to its cleistogamous nature creation of variability through artificial hybridization is difficult so mutation breeding occurs as the cleanest approach to induce desirable changes in the crop. Present study was undertaken to study genetic variability and character association in M3 generation of Urdbean and to find out promising mutant lines for yield and protein content. Gamma rays irradiated 72 mutants from parent varieties PU 1 and CO 6 were evaluated in kharif, 2019 in Augmented design in four blocks along with five check varieties including parental varieties viz., PU 1, CO 6, MU 2, TPU-4, KU 96-3 in Research farm, Sri Karan Narendra Agriculture University, Jobner, Jaipur. Analysis of variance depicted sufficient genetic variability for most of the characters. Mutations were induced in both the directions. Heritability and Genetic advance were high for the characters seed yield per plant and pods per plant. GCV and
