Abstract:
450 exotic and indigenous rice germplasm were screened for reproductive stage drought stress under natural field conditions out of which 30 genotypes were selected for further study. The present study was undertaken for characterization of the selected rice genotypes, along with 8 checks, for nine important agro-morphological and grain quality traits. ANOVA revealed significant differences among the genotypes for all the variables observed. In general, all the traits under study were found to be having a decreasing trend under reproductive stage drought. The line Pakistanhmwe and Lwankhan showed highest and lowest grain length (mm), respectively. Dubraj was reported having maximum amylose content of 25.44% while it was very low, only 4.72%, for the genotype ARC 11322.
