According to contemporary bibliographical sources, the maternal factor has an important role in resetting the genetic formulas underlying the phenotypic manifestation of quantitative characters, but the mechanisms of phenomenon, at the moment, are quite uncertain. By researching the influence of the maternal factor on the effects of gene involved in the control and heritability of biological characters and productivity of tomato it was found that the maternal factor strongly influenced the level, the orientation and the variance of gene effects which control the quantitative characters of the tomato fruit. Changing the level of the heritability coefficient in a broad sense in reciprocal crosses reveals the influence of the maternal factor on the rate of participation of the genotype in the formation of phenotype quantitative character and its hereditary transmission capacity. |
