Mutagenic effect of Gamma rays and EMS on yield attributes of Sorghum (Sorghum bicolor (L.) Moench) in M1 generation

The traditional varieties of Sorghum have low potentiality and restricted variability with respect to economic characters. Broadening the genetic base for crop improvement can be quickly achieved through induced mutagenesis. The present study was undertaken in order to comparing the effectiveness and efficiency of mutagens in M1 generation. In this regard, CSV-23 Variety of Sorghum was subjected to different concentration of Gamma rays (20, 30, 40, 50 and 60 Kr) and EMS (20, 30, 40, 50 and 60mM) for inducing mutation. The effect of Gamma rays and EMS with different doses/conc. On mutation frequency and mutagenic effectiveness were observed in M1 generation. The survival percentage and mean value of M1 generation were decreased with increasing doses/conc. of treatment. Mean performance of different quantitative traits were observed better in control when compared to treated plant and also I observed that the LD50 was found at 30Kr of Gamma rays and 40mM of EMS. And these two treatments will be observed and concentrated for the further studies to develop the good yield and crop improvement in qualitatively and quantitatively.
