Background: Induction of mutation plays an important role in the breeding programme among modern methods of plant breeding. Genetic variability is prerequisite for crop improvement and through induced mutation it was found to be very effective for creating variability in the quantitative and qualitative characters. Hence, the present study was aimed to induce genetic variability within short time. In the present investigation positive as well as negative impact on quantitative traits were recorded. Methods: The experiment material comprised of seeds of horsegram [Macrotyloma uniflorum (Lam.) Verdc] variety Paiyur 2 which was subjected to ethyl methane sulphonate (02, 0.3, 0.4 and 0.5%), gamma radiation (100, 200, 300 and 400 Gy) and combination treatments. The mutations affecting gross morphological changes in growth and yield characters such as plant habit, flowering, pod morphology, maturity and seed yield were scored as quantitative characters. The micro mutations at population level can be easily detected in the form of increased variations for quantitative traits in the segregation of mutagen treated populations. Micro mutations can alter morpho-physiological characters hence they are of a particular interest to the plant breeders. ANOVA test was performed to determine the significant differences and duncan’s multiple range test (p=0.05) to compare the differences among treatment means. Result: Among the twenty-five treatments studied both the mutagens, gamma radiations and Ethyl Methane Sulphonate proved to be very effective to induce variability in quantitative traits in M2 and M3 generations. The results of Duncan’s multiple range test analysis revealed that the treatment of mutagens in combinations induced more positive effects as compared to that of using alone. The combined treatments were found positive for improvement of primary branches per plant, no. of pods per plant, pod length, no. of seeds/pod and seed yield per plant in M2 and M3 generations whereas the treatment of gamma irradiation imparted its significant role for improvement of plant height, days required for 50% flowering, days to maturity and 1000 seed weight in both M2 and M3 generations whereas the treatment with Ethyl Methane Sulphonate is useful for improving no. of pods per plant and no. of seeds/pod in M2 generation alone.

A study was conducted to estimate the effects of gamma rays and ethyl methane sulphonate (EMS) on mutagenesis of Pearl millet. Gamma rays (10, 20 and 30kR) and EMS (20, 30 and 40mM) treatments were done to find out different quantitative traits viz., Days to first bloom, Plant height, Number of leaves, Number of nodes, Length of earhead, Breadth of earhead, 1000 grains weight, Yield per plant, Chlorophyll and carbohydrate content. These parameters were better in 20kR of gamma rays and 30mM of EMS when compared with the control and other doses/concentrations and higher doses decreased the parameters.

Seeds of two pigeonpea varieties namely BDN 708 and BSMR 853 were treated with Gamma rays, ethyl methane sulphonate (EMS) and Sodium azide (SA). The treated as well as control plant populations were screened to study the induced variability for quantitative characters. Positive shift in mean values for number of primary branches per plant was observed except 0.10% EMS in variety BSMR 853 and BDN 708 in M2 generation. The effect of all the mutagenic treatments on pods per plant revealed statistically significant negative as well as positive shifts in mean values in BSMR 853 in M2 and M3 generations.

SUMMARYWild-type Friend murine leukaemia (clone 707) cells and two thymidinekinase-deficient subclones, 707BUE and 707BUF, were compared for sensitivity to killing and mutagenesis by the chemical mutagens, ethyl methane sulphonate (EMS),N-methyl-N′-nitro-N-nitrosoguanidine (MNNG), mitomycin C (MMC), and methyl methane sulphonate (MMS). The two thymidine-kinase-deficient subclones were significantly more sensitive to killing by each of the four chemical mutagens than were wild-type cells. The increased sensitivity to killing by the four mutagens was also reflected in increased mutagenesis (per unit dose of mutagen) to 6-thioguanine resistance. In the light of these results, the significance of thymidine kinase in DNA repair and mutagenesis is discussed.

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.
