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.

Present investigation deal with the study of mutagenic effect of Ethyl Methane Sulphonate (EMS) on mulberry variety M5. The results revealed that at 0.4% EMS treatment, height of the plant and leaf area were considerably increased. Stem dichotomy, fusion of leaves, increase in thickness, change in texture of leaves and occurrence of albino and xantha were common in 0.3% EMS treated plants in M1 generation.

Effectiveness And Efficiency

This study was carried out to determine the frequency of lethality, Mutagenic frequency, effectiveness and efficiency induced by ethyl methane sulphonate (EMS) and sodium azide on foxtail millet. The seeds were treated with different concentrations of EMS and sodium azide. Number of morphological mutant were observed visually and recorded. Mutagenic frequency, effectiveness and efficiency were highest for EMS at 0.1% concentration (Mutagenic frequency 7.50% effectiveness 18.75% and efficiency 7.50%) and sodium azide at 0.2% concentration (Mutagenic frequency 7.00%, effectiveness 1.84% and efficiency 1%). Lower concentrations of EMS and sodium azide were more effective and efficient in inducing mutation with low biological damages and high mutation frequency. EMS was more effective and efficient in inducing variability in foxtail millet than sodium azide. Therefore, mutants foxtail millet with low biological damages and high mutation frequency can be developed at low concentration of EMS and sodium azide for breeding of foxtail millet.
