23. Correlation and regression relations between grain yield, the yields element and some biometrics parameters of late maize hybrids Kn 625 and Kn M 625

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.
