Frequency of mutations (Chlorophyll, foliar and agronomic) have been reported following seed treatment of grasspea cv. Dhenkanal local with - rays, EMS, NG and their combinations at varying doses. NG was the most potent mutagen for induction of mutation followed by EMS and -rays . Combination treatments showed synergistic effect for mutation frequency. EMS and NG, singly or in combination with -rays, were more or less equipotent in inducing agronomic mutations, while,  - ray was less effective.


Mutation frequency - rays Ethyl methanesulphonate (EMS) N-ethyl-N-nitro-N-nitrosoguanidine (NG) Lathyrus sativus.
