Sum rules for light quarks are obtained in the framework of quantum chromodynamics. The predictions of QCD for the decay widths rho..-->..e/sup +/e/sup -/ and phi..-->..e/sup +/e/sup -/ are found to be close to the experimental values. The mass of deep-inelastic light quarks is calculated to be m/sub ..mu../+m/sub d/approx. =10 MeV. Corrections to the Weinberg sum rules due to operators with higher dimensions are discussed.
