Abstract:

Induced mutagenesis used to investigate the different treatments of gamma irradiation viz., 20, 40, 60, 80 and 100kR and Ethyl Methane Sulphonate (EMS) viz., 5, 10, 15, 20 and 25mM on growth and yield parameters of black gram Vigna mungo var. VBN1. Present study revealed that based the physical and chemical mutagenic sensitivity of black gram was compared to control as well as treated plants. In this investigation, all the quantitative characters and yield characters were stimulated from 20 to 60kR and 5 to 15mM of gamma rays and EMS the inhibition occurred more in 60kR and 15mM. Among these two mutagens results showed EMS (15mM) was found to be more effective and improved the yield characters compared to those of gamma rays treatment.
