英文摘要	Seventy diverse genotypes were evaluated for drought stress for morphological (shoot and root length, fresh and dry shoot weight, fresh and dry root weight) and physiological traits (stomatal conductance, photosynthesis and transpiration rate) to increase the area under arid and semi-arid climatic condition to overcome the deficiency of edible oil. All genotypes varied significantly for all evaluated traits. High variability for photosynthesis rate and lower for transpiration rate but highly significant. Genotypic variance and its coefficient are almost higher for all characters then environmental variance and its coefficient. Additive gene action was found for stomatal conductance and fresh root weight, good characters for selection having high heritability with increased genetic advance used to find out drought tolerating genotypes. Genotypes ORI 29 and ORI 30 performed better in normal and drought stress condition can be used further breeding programme as a drought tolerant material. In PCA, genotypes ORI 30, ORI 27, ORI 38 and ORI 105 expressed maximum diversity can be used in further hybrid programme.
