Physical and chemical mutagens have induced various types of mutations useful in the improvement of crops. In recent years it has been shown on various plant species that the effect of mutagen treatment varies with varying doses and varying periods of treatments. The paper reports the results of application of 5kr, 10kr and 15kr of gamma rays and 0.02% of Nitroso Methyl Urea (NMU) on Khesari ( Lathyrus sativus ) var. P-24. Saperate and combined doses of gamma rays with 0.02% NMU were used for mutagenic effects. Observations for M2 generation were recorded at a regular interval. Mutants for seedling morphology like curled apex, stunted seedling, radicle hypertrophy, folded leaflets and mutants for plant height like dwarfs, stunted, branching habit mutants, leaf mutation and mutants for flowering were observed.

Gamma rays, NMU, induced mutation, grass pea.
