摘要：ABSTRACT: A study was conducted to assess the effects of physical mutagen gamma rays and a chemical mutagen EMS on rice cultivar ADT (R) 47 to study the morphological variations in this variety. For inducing macro and micro mutations, the dose applied were 200Gy, 250Gy and 300Gy of gamma rays and 100mM, 120mM and 140mM of EMS. In initial evaluation trial (M 1 ), the germination percentage, seedlings survival percentage, plant height on 30 th day, pollen fertility, plant height at maturity, seed fertility showed a dose dependent reduction for both the mutagens. Among the various traits, seedling height on 30 th day and the plant height at maturity exhibited less variation between the mutagens. KEY WORDS: Mutagenic effects, Gamma Rays, 47 Rice.
