Mutational rectification of plant type of Dhairal, a local tall indica rice variety, for introducing responsiveness to nitrogen was attempted. When the several mutant strains, selected on the basis of plant type, were grown at different levels of nitrogen, selection × nitrogen interaction and difference amongst selections was noted to be highly significant. Moreover, the existence of high genotypic variance for grain yield at high level of nitrogen indicated changes in spread of lines and selection at high nitrogen level to be worthy.
