Additive X additive effect (i) of the major genes plus polygene was found to be 44.
The polygene heritability (hpg2) values were estimated as 6.
In this process of selection, other polygenes are given a little emphasis (i.
This showed that the optimization of emphasis given to QTL balanced substantially the relative weight between QTL and polygene in the selection criterion.
heritability for grain filling duration was higher than heritability due to polygene in BC1 BC2 and F2 for the crosses with highest environmental influence.
Genetic effects for controlling grain filling duration in terms of polygene in wheat have previously been determined using either diallel or generation mean analysis as statistical procedure.
Synergistic interaction of spontaneous mutant polygenes
Furthermore, because the resistance conferred by these lines is under single gene control and the genotypes produce a highly resistant phenotype, the expression of resistance should not be as sensitive to environmental factors as that of moderate resistance controlled by polygenes
Relationships between the polygenes
affecting the rate of development and viability in Drosophila melanogaster.
1994) have pointed out that many economically important characters are qualitative-quantitative ones, which are controlled simultaneously by one or a few major genes and modified by polygenes
Other "wide" crosses are made with the objective of incorporating alleles of polygenes
from an exotic parent that is often unadapted to the breeder's targeted region of crop production.
This strong correlation indicates that both characteristics are influenced in the same way by the same set of polygenes
