Abstract
TH E variations occurring in segregating popula- tions of corn are attributable to three main sources: namely, additive genetic effects, nonadditive effects due to dominance and interaction of nonallelic genes, and environmental effects. The term genotypic variation is used throughout with reference only to the additive genetic or heritable variation which is the portion of the variation responsible for progress resulting from selection. Phenotypic fluctuations may result from combinations of all of these types of variations, Since the breeder is concerned with selecting superior genotypes, but of necessity must choose individuals from their phenotypic expressions, estimates of the genotypic and phenotypic variances for various characters are needed...
