Abstract Information on the combining ability, heterosis and inheritance of agronomic
characters in white corn (Zea mays) is required for hybrid development. The lack of
information prompted this study to determine combining ability estimates and the relative
magnitude of genetic components for plant height, ear height, silking date, relative growth
rate, kernel rows, kernels per row, kernel weight, and grain yield in white corn. Eight parental
inbred lines and their 28 F1 progenies were evaluated in replicated field experiments at …
