摘　　要：为制定科学的蛋品质选育方案,本研究以"京粉1号"配套系纯系为研究素材,通过连续测定3个世代36周龄蛋品质性状指标,对主要蛋品质性状的遗传参数进行估计。结果表明:A、C、D系蛋重的遗传力均大于0.4,属于中等偏上遗传力性状;A系蛋壳强度、蛋白高度、哈氏单位、蛋黄颜色的遗传力均低于0.3,属于低遗传力性状;C系和D系的蛋白高度、哈氏单位的遗传力估计值在0.3以上,属于中等遗传力性状,而蛋壳强度、蛋黄颜色的遗传力较低(0.16~0.26)。本研究明确了不同蛋品质性状在各品系的遗传规律,说明在制定选育方案时,应根据各品系的蛋品质性状特性采取不同的选育方法,增加选育效率,提高遗传进展。The present study was conducted to estimate the heritability and genetic correlations of traits related to egg quality in layers from pure line A, C, and D of ＂Jing Tint 1＂ package. Egg quality traits at 36 weeks of age were measured in three successive generations and genetic parameters were evaluated to provide essential data for making up scientific egg quality breeding program. The results showed that heritability for egg weight of line A, C, D was medium to high （0.46-0,59）. The heritability was relatively low for eggshell strength, albumen height, Haugh unit and egg york color of line A （0.17-0.29）. The heritability was medium for albumen height and Haugh unit of line C and line D （0,34-0.43）, while it was low for eggshell strength and egg York color （0.16-0.26）. The current study demonstrated the genetic parameters of egg quality traits in different lines, suggesting that the breeding methods should be adjusted according to genetic characteristic of egg quality in different lines to improve breeding efficiency and accelerate genetic progress.
