An attempt was made to evaluate eighteen physio-morphological traits and grain yield in eighteen genotypes of upland rice under irrigated and flowering stage drought condition. High estimates of phenotypic (PCV) and genotypic (GCV) coefficient of variation were observed for sterile grains per panicle, grain yield apparent contribution rate, water potential, straw yield and total biomass at maturity in drought stress condition. Fourteen out of nineteen characters under study showed higher PCV and GCV values in drought condition as compared to corresponding estimates in irrigated condition which indicated that water stress was responsible for expressing greatest degree of variability in case of most of the physio-morphological traits in the same material. | Evaluation of physio-morphological traits in upland rice under water limited environment
