Abstract

This paper presents theory and analysis of partial diallels, using data from the parents and F₂ generations obtained from crossings among two groups of parents. Theory and analysis are based on Hayman's 1954 and 1958 suggestions. The diallel analysis allows the characterization of the polygenic systems under analysis through the estimation of genetic and non-genetic components of variation, in relation to each group of parents or to each parent, depending on the component and on the genetic parameter. The genetic parameters are the mean products of the allelic gene frequencies, mean degrees of dominance, mean proportions between dominant and recessive genes in the parents, direction of dominance and heritability. A diallel analysis for the common bean is included
