Biochemical changes in resistant and susceptible to leaf curl virus of two cotton cultivars were assessed by a series of laboratory experiments. All the growth attributes proved S-12 (CLCuV Susceptible) superior to CIM-446 (CLCuV Tolerant). Oil content along with its hydrolyzing enzyme lipase were significantly higher in S-12 than that of CIM-446. The higher germination of S- 12 seemed to be determined by higher oil content and oil hydrolyzing enzyme lipase. High protein content in all the embryonic parts of CIM-446 might play an important role in providing better fulfillment of structural requirements to resist virus at vegetative growth stages by contributing to higher composition of antibodies or some other physiological responses associated with proteins.
