Abstract
The experiment consisting induced mutation in groundnut were performed by exposing the healthy and dry seeds to gamma rays viz.,20, 30 and 40 Kr doses and ethyl methane sulphonate (EMS) viz.,40mM and 60mM. The observations were made for seed quality parameters such as root length, shoot length, seedling length and vigour index, in the treated plants The experimental material were evaluated in CRD design. The experimental results revealed that the percentage of germination had decreased after irradiation and the effect become stronger with increase of gamma dose. Parameters such as germination percentage, speed of germination, mean daily germination, peak value and germination value had significantly decreased with increased irradiation doses. Similarly seedling parameters viz., Root length, Shoot length, Vigour index and Root/Shoot length ratio expressed higher reduction at higher doses as compared to no irradiated control. Based on the variation in seed quality parameters of gamma rays and EMS treated plants, superior strain will be screened by PCR-RAPD marker and published in the near future
