Abstract

To investigate the effect of crosses in maize ears, five genotypes were hybridized .one genotype of each of (Z. mays L.)Sub-species (Everta, indurate, Indentata, Saccharata and the Wight endosperm Denprofeski) were intercrossed.F1 and F2 kernels and F1 ears were investigated. The results showed that hybrid vigor or dominance was controlling ears traits. They were controlled by female nuclei indicating the effect of two nuclei of female genes on one nucleus of male pollen. ,It was dominance or hybrid vigor controlling ear traits in maize
