6Rice production is severely threatened by drought stress in Eastern India. To develop drought tolerant 3 7 varieties, selection of donors for breeding programme is crucial. Twenty one selected rice genotypes including 3 8 both tolerant and sensitive to drought were grown under well-watered and drought stress conditions in dry 3 9 seasons of two successive years of 2017 and 2018. Leaf water potential, relative water content displayed 4 0 significant difference among the genotypes during vegetative screening. At reproductive stage drought 4 1 screening, days to 50% flowering was delayed in all genotypes except N22 and Anjali (showed early flowering) 4 2 however grain yield and other yield related traits decreased significantly compared to well-watered condition. 4 3 Correlation analysis of phenological and yield related traits with grain yield revealed that tiller numbers and 4 4 panicle numbers are highly correlated with grain yield both under well-watered and water stress conditions and 4 5 contributes maximum towards grain yield. The dendrogram grouped Mahamaya, Sahabhagidhan, Poornima, 4 6 IBD 1, Hazaridhan, Samleshwari and Danteshwari into one cluster which performed better under water stress 4 7 conditions and had grain yield more than 1.69 tha -1 . Sahabhagidhan, Poornima, Vandana, and N22 displayed 4 8 tolerance to drought both under vegetative and reproductive conditions which could be a good selection for the 4 9 breeders to develop drought tolerant rice cultivars for eastern region of India.5 0
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
