Abstract
In recent decades, a large number of crop types have been developed using mutation breeding. In present investigation, gamma irradiated indica rice cultivar Rajendra Mahsuri 1 were morphologically analysed for identify candidate mutants. M3 mutant lines were screened using eleven morphological characteristics. Morphological investigations revealed that gamma irradiation created enough variability for selection of specific traits. We have observed huge variation in maturity (105 and 135 days) and plant height (45 to 160 cm) in M3 mutant lines. The results of morphological analysis showed a great deal of potential for identifying beneficial mutations caused due to gamma irradiation.
