The correlation-regression relation between grain yield, the yields element and some biometrics parameters of late maize hybrids KN 625 and KN-M 625 were tested. Positive correlation and regression relation between grain yield and mass on grains per ear (R=0,43 and R=0,45), length of ear (R=0,26 and R=0,46), grains per ear (R=0,39 and R=0,51), plants height (R=0,57 and R=0,53) and ear leaf area (R=0,81 and R=0,63) is found. Negatively correlation relation between grain yield and lines per maize ear (R=-0,03 and R=-0,45) is found.
