Abstract

Seven mutants with changes in grain size and in pigmentation of various organs were isolated in the M 2 and M 3 generations of the Patnai variety of winter rice after treatment with (32) P and (35) S. Some of these could be useful for breeding.The narrow grain mutant, isolated in the M 3 generation after treatment with (32) P, was high-yielding and had fine grains and an increased number of long panicles.Two short grain mutants with changed husk colour were obtained in the M 2 generation after treatment with (32) P. One was also early maturing.One purple apiculus and three purple husk mutants were isolated in the M 2 generation after treatment with (35) S. Some of these also had reduced plant height and short grains. The purple apiculus mutant bred true for stigma and apiculus colour, but segregated for leaf sheath colour. In purple husk mutants the segregation of mutant characteristics was unusual and there was manifestation of new characters.
