摘　　要：本研究以黑羽绿壳蛋鸡(P1)和白来航鸡(P2)为材料,测定P1、P2及其F1、F2代的40周龄蛋重,应用SEA-G4F2软件分析蛋重遗传规律。结果表明,40周龄蛋重为2对加性-显性-上位性主基因+加性-显性-上位性多基因混合遗传模型(E模型),主基因遗传率为0.4307,多基因遗传率为0.0254,主基因的遗传率远大于多基因的遗传率。Black feather green shell layers （P,）and White leghorn chickens （P2） were used as materials in this study, egg weight at 40 weeks of age of P1, P2, F, and F2 were measured, and the analysis software of the genetic regular pattern in egg weight was SEA-G4F2. The results showed that the model of egg weight at 40 weeks of age was two pairs of additive-dominance-epistatic major gene plus additive-dominance-epistatic polygene mixed inheritance model （model E）, the heritability of major gene was 0.4307, polygene heritability was 0.0254, the heritability of major gene was larger than polygene.
