- Abstract
Production is, perhaps, the most complex trait and, in comparison with other quantitative traits, It is the hardest to evaluate in the early generations of selection, which is primarily due to the high state of heterozygosity and to the great number of major and minor genes implied in the heredity of 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 genetic populations from the lineages were analysed, the following being estimated: additive genetic effects (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.
