The phylosophy of intrapopulation combined selection is the search for and identification of individuals with superior genotypic behavior, based on their performance compared to the family mean and, at the same time, of their family mean in relation to the population mean, through the weighting of the phenotypic values represented, respectively, by the within and among families heritability coeficient. The objective of this study was to adapt and apply this philosophy ti diallel analysis. The crosses were considered as having fixed effects and selected on the basis of their specific combining ability (SCA), and on the mean performance of the two involved parents, in relation to the general combining ability (GCA). This work was based on Griffing's (Heredity 10; 35-50, 1956) method 2, model 1 which involves p(p+1)/2 treatments. The proposed index result from the weighting of the effects of GCA (gi's) and SCA (sij's) by the respective determination coefficient of additive and dominant genetic determinations, resulting from the partitioning of the total genotypic determination coefficient. An example is given for illustration. |
