Gamma Rays and EMS Induced Flower Colour and Seed Mutants in Sesame (Sesamum indieum L>.)

摘要

The present study was carried out to induce genetic variability in sesame through mutation. Seeds were subjected to different treatment levels of gamma rays and ethyl methane sulphonate (EMS). The treated plants were self-fertilized for generations toobserve different morphological characters in M, generation. Several unique and interesting mutants were isolated in this investigation. These independent mutants had different phenotypes fromthe control. Highest mutation frequencies for flower colour and seed characteristics were found to be induced by 400Gy gamma rays and by l.Oper cent EMS in VRI2. The most distinct mutants isolated were flower colour variants along with altered size, shape and coat colour of seeds.
