Induced variability was studied in the quantitative characters of mung bean (Phaseolus aureus Roxb.) after treatment with gamma rays, ethyl methane sulphonate (EMS), and hydrazine hydrate (HZ) in M1, M2, and M3 generations. The characters evaluated were seeds per pod, 100-seed weight, and total plant yield. The variability increased in almost all of the characters in the M1 generation. The mean number of seeds per pod and 100-seed weight decreased, whereas the plant yield did not show any particular trend. There was an increase in the mean values after gamma irradiation and EMS treatments in the M2 generation. However, HZ fails to show the same response. However, the mean values increased in the M3 generation. Estimates of heritability were higher for 100-seed weight, followed by plant yield, and then seeds per pod in the M3 generation. Coefficient of genotypic variation and genetic advance were high for the plant yield in M2 and M3 generations. In general, the genotypic coefficient of variation values, heritability, and genetic advance increased more in M3 as compared with M2, indicating that the significant gain could possibly be achieved through selection in M3 generation.Key words: quantitative, heritability, mutagenesis.

Soybean (Glycine max (L.) Merr.) var. Co-1 seeds were treated with physical mutagen namely such as gamma rays and chemical mutagen namely such as Ethyl Methane Sulphonate (EMS) and Diethyl Sulphate (DES). Various concentrations of gamma rays 10, 20, 30, 40, 50 and 60 KR, EMS (0.1, 0.2, 0.3, 0.4, 0.5 and 0.6 %) and DES (0.1, 0.2, 0.3, 0.4, 0.5 and 0.6 %). The morphological parameters such as days to first flower, plant height, number of cluster per plant, number of pod per plan, seed yield per plant, number of branches per plant, number of leaves per plant, protein content and oil content increasing with increasing level of some doses gamma rays, Ethyl methane sulphonate and Diethyl sulphate treatment in M2 and M3 generation were carried out. A number of mutants were recorded in M2 and M3 generations for one or more traits viz., plant height, maturity, branching, pigmentation, fruit size and yield were isolated in M2 and M3 generation. Mean for various characters increased at mutagenic treatment than control. The yield parameters like plant height, number of cluster per plant, number of seeds per plant and seed yield per plant were recorded the moderated and high mean value in the 50 KR of gamma rays 0.5% of EMS and 0.4% of DES treated population with compared to control plants.

Different Doses

A relative study of frequency and spectrum of chlorophyll mutations induced by mutagens in M2 generation was made with chickpea (Cicer arietinum (L). Variety ‘CO-4’. The treatments include different doses/concentrations of Gamma rays (20, 30, 40, 50 and 60kR) and Ethyl Methane Sulphonate (10, 20, 30, 40 and 50 mM). From the study, the overall frequencies and spectrum of five types of induced chlorophyll mutants Viridis (0.55), Xantha (0.46), Chlorina (0.45), Albina (0.43) and Tigrina (0.35) were observed. The frequency of chlorophyll mutation was increased with increasing concentrations up to a level, beyond it declined in both the mutagens. And the chlorophyll frequency was found in the order of viridis > xantha >chlorina> Albina >tigrina. The chemical mutagen, EMS was found to be more effective in inducing chlorophyll mutations than gamma rays in Chick pea.

Three mutagenised populations each of gamma rays, sodium azide (SA) and ethyl methane sulphonate (EMS) showed increased amount of variability over control for different polygenictraits in both <italic>macrosperma</italic> (LH90-54) and <italic>microsperma</italic> (LH89-48) lentil cultivars in M<sub>2</sub> generation. Among the mutagens tested, EMS induced maximum variability for all the traits, followed by gamma rays and SA in both the cultivars. The highest frequencies of mutated [M<sub>2</sub> progenies with higher coefficient of variation (CV) than the corresponding highest CV in control for any of the traits] and promising progenies [M<sub>2</sub> mutated progenies where mean shifted in the desired direction] were induced by different mutagens in the order:EMS > gamma rays > SA in both the cultivars (LH90-54 > LH89-48). In LH 90-54, promising progenies with multiple traits were induced with the highest frequency by SA, followed by EMS and gamma rays, whereas in LH89-48, they were induced with the highest frequency by SA, followed by gamma rays and EMS. Invariably, the medium dose of mutagens (0.08%SA, 0.40% EMSand 10 kRgamma rays) induced maximum variability(CV, %), resulting in thehighest number of promising progenies for all the polygenic traits.
