Abstract

Correlation and path coefficients were studied in a set of 65 maize genotypes. High positive association was observed between grain yield on the one hand, and plant height, ear length, ear weight, number of kernels per row, dry matter production and harvest index on the other. The inter correlations among these traits were also significant. Path coefficient analysis revealed that selection on any trait in maize will influence the grain yield only through dry matter production.

Keywords: Correlation, Component Analysis, Maize
