Abstract:

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. High estimates of heritability in broad sense coupled with high genetic advance in per cent of mean were recorded for water potential, fertile grains per panicle, sterile grains per panicle, straw yield, total biomass at flower total biomass at maturity, ACR, root length, root volume and grain yield in both conditions and panicle length, ATR, membrane thermo stability and root dry weight in drought conditions only. The physico-morphological traits exhibiting high heritability and genetic advance would provide high response to selection practiced for their improvement.
