Abstract:
During Kharif-2014, a field study was conducted with two high yielding CRIDA castor genotypes, <em>viz</em>.,CRC-2 and CRC-9along with the check 48-1under irrigated and moisture stress conditions to assess their variability and genetic advance for seed yield and physiological traits <em>viz</em>., ELWRC, RWC, Pn, gs, Tr and WUE. Significant variability was observed among the genotypes for all the characters studied.CRC-9 performed better than the check for the four physiological traits studied <em>viz</em>., ELWRC, Pn, gs and WUE under both irrigated and moisture deficit stress conditions. Whereas, CRC-2 performed better than the check for two physiological traits <em>viz</em>., gs and Tr under moisture deficit conditions only.High heritability with high genetic advance was recorded for Pn under both the conditions studied while for gs and Tr under moisture deficit stressonly indicating the predominance of additive gene action in inheritance of these characters. Hence, these traits can be taken into consideration for the improvement of castor.
