Castor (Ricinus communis L.) an important non edible oil seed crop has great industrial value. India has been one of the major contributors in production and trade of castor oil and its derivatives. 400 castor F2 mapping population generated from a cross between PCS 106 and PCS 345 was studied for the variability in ten WUE related physiological traits and six yield contributing traits. The study was conducted during Kharif season of 2015-16. The data was subjected to analysis of variance and was found that the germplasm differed significantly for all the characters studied. The estimates of genotypic and phenotypic variances were worked out for all the characters. While considering the WUE traits high GCV estimates were observed for leaf area (34.74%), photosynthetic rate (20.62%), stomatal conductance (28.50%), transpiration rate (36.32%) and extrinsic WUE (40.57%). In the present investigation both WUE related and yield characters showed high heritability (>60%) indicating low environmental effect and high capacity of the characters for the transmission to subsequent generation.
