Production is, perhaps, the most complex trait and, in comparison with other quantitative traits, itis the hardest to evaluate in the early generations of selection, which is primarily due to the highstate of heterozygosity and to the great number of major and minor genes implied in the heredityof this trait. The research undergone reached the conclusion that, in their turn, the elements of production possess a complex heredity. To estimate the effects of heredity gene involved in quantitative characters, yield component, it was used for genetic analysis model proposed by Hayman (1958) and applied by Gamble (1962). In this regard, the averages of the traits from the parental populations and from the geneticpopulations from the lineages were analysed, the following being estimated: additive geneticeffects (a), dominant (d) and the epistatic interactions of the type additive x additive (aa), additivex dominant (ad), dominant x dominant (dd), involved in the heredity of the analysed traits.
