Development of rice mutants with enhanced resilience to drought and brown spot (Bipolaris oryzae) and their physiological and multivariate analysis
Under the testing conditions, six of the nine analyzed components revealed positive loadings in PC-1. The stress tolerance indexes together with brown spot disease index along with rate of transpiration and rate of photosynthesis in stress condition showed greatest influence on PC-I. Analysis of present studies demonstrated five clusters among mutants and their parent line and commercial variety. The cluster-I contained fifty-four mutants and cluster-II consisted of six mutants and cluster-III consisted of four genotypes followed by two mutants alongside one genotype which enabled crucial research for rice breeding to enhance stress tolerance and disease resistance.
