Gamma rays induced mutations in Basmati rice (Oryza sativa L.)

Abstract

The important objectives in improving Basmati rice are to develop short statured, high yielding, early maturing and disease resistant varieties. Mutation breeding is relatively a quicker method for the improvement of crops [1]. Many physical and chemical mutagens have been used for induction of useful mutants in rice [2]. The present article deals with the observation on seedling growth injury and spikelet sterility in M1 generation and chlorophyll and morphological mutations in M2 generation in Basmati rice (O/}'za sativa L.) induced by gamma rays.
