摘要： 性多基因混合遗传模型，主基因遗传力为1471%；蛋白高度、蛋黄重和蛋黄颜色的适合模型均为模型E\|1，即两对加性-显性-上位性主基因+加性-显性多基因混合遗传模型，其对应的主基因遗传率1932%，358%和2105%，多基因的遗传率为0。

Abstract: In the present study， black feather pure lines of green\|eggshell and white leghorn were selected as parents to construct resource population. The traits of albumen height， yolk weight， yolk color and Haugh unit of eggs laid by P1 and P2 parents as well as their F1 and F2 offsprings at 40 weeks were measured. SEA\|G4F2 software was used for the mixed gene plus polygenes inheritance analysis. It was shown that the model of Haugh unit at 40 weeks age was E， namely two pairs of additive\|dominance\|epistatic major\|gene plus additive\|dominance\|epistatic polygene mixed genetic model， in which the heritability of major\|gene was 1471%. The optimal models of albumen height， yolk weight and yolk color were model E\|1， namely two pairs of additive\|dominance\|epistatic major\|gene plus additive\|dominance polygene mixed genetic model， in which their heritability of major\|gene were 1932%， 358% and 2105%， respectively. The heritability of polygene for each trait was 0.
