英文摘要	Seventy diverse genotypes were evaluated for drought stress for morphological traits i.e. days to flowering, days to maturity, head diameter, number of leaves per plant, stem girth, thousand seed weight, achene yield per plant and oil percentage to find out trait specific genotypes. All genotypes showed highly significant (P <= 0.01) mean square values for all traits. Head diameter expressed highest and significant genotype mean square (5366.93) and days to flowering showed lowest but significant genotype mean square (23.71) in all traits. Achene yield per plant and thousand seed weight having high heritability with increased genetic advance indicated additive gene action and lesser influence of the environment. The characters like days to flowering, days to maturity, head diameter, number of leaves per plant, stem girth and oil percentage showed non-additive gene action. Genotypes ORI 29 and ORI 30 performed better in normal and drought stress conditions that could be used as a drought tolerant material. In Principle Component Analysis (PCA), genotypes RL 110, RL 109, ORI 58, ORI 22, ORI 30 and RL 77 expressed maximum diversity. The bi-plot graph presented that genotype RL 104 had maximum number of leaves per plant, ORI 88 had maximum stem girth and head diameter; however, ORI 25 had high oil percentage value while days to maturity and achene yield per plant were found higher in ORI-66 and ORI-101 under normal and drought stress conditions. The trait-specific accessions will be helpful in effective exploitation of prominent genotypes for drought tolerant breeding programme. Drought tolerant genotypic identification could overcome the shortage of edible oil in country by increasing area and production under arid & semi-arid climatic condition.
