Abstract

Six ear-kernel characters of two heterotic maize populations were analyzed under two planting densities.The results showed that ear-kernel characters were all complex quantitative traits in heredity.High planting density deteriorated all the characters,except ear diameter,and increased the variations of all characters,except 100-grain weight for the non-Reid population.High planting density was favorable for phenotypic selection of ear-kernel characters.Ear-kernel weight and ear length were the suitable selection criterion in planting density stress.Compared to non-Reid population,Reid population was less influenced by planting density.Ear-kernel weight was determined commonly by all ear-kernel characters.Great attention should be paid on coordinating the relations among different ear-kernel characters during the inbred line development from Reid population.
