Description:	Obtained g and Sii values were associated to theoretical concepts of the respective parameters in a complete diallel with 28 parents and the simulation of five hypothetic variables with five different d/a relations (0, 0.5, 1.0, 1.5, and 2.0). These were controlled by a single gene with two alleles whose parents were represented by different frequencies of the favorable allele (1/28, 2/28,....,28/28). The conclusion was drawn that the existence of dominance deviations in the loci regulating the trait influences the GCA estimates considerably and that there is a high correlation (0.96) between the absolute Sii and the respective values. The joint evaluation of g1 and Sii estimates provides information on the genetic quality of the populations of the diallel.
