Correlation relations between grain yield, elements of productivity and some biometrics parameters of inbred maize lines maize

Резюме: A research has been made over the correlation and regression relations between the yield, the elements of the productivity and some biometric indicators of inbred maize lines.
Strong positive correlations were identified between the yield and three of the components of the productivity- the length of the cob, the grain’s weight of the cob and MKV; middle strength correlation between the yield and the number of grains in row and medium to low correlation between the yield and the biometric indicators of the plants.
The results can support the selection process in creating genotype with the wanted indicators, based on the established correlative connections between them.
