MUTATION studies in rice, Oryza sativa were initiated by Ichijima (1934) in Japan
and Ramiah and Parthasarathy (1936) in India. The mutants secured in their studies
were chlorophyll deficient or teratological abnormalities which have not roused much
interest among plant breeders. More recently, however, workers in U.S.A. (Beachell,
1957), China (Chang, 1959), Japan (Masima and Kawai, 1958) and India (Bora
and Rao, 1958) reported different viable mutants which might serve as useful breeding
material for the improvement of this crop. The present study was undertaken to
determine the morphological and cytogenetic changes accompanying radiation
with three mutagens, and to determine whether the mutation spectrum can be altered
by employing specific mutagens.
