摘　　要：用父系半同胞组内相关法 ,对豫州褐壳蛋鸡 系四世代的部分数量性状的遗传参数进行了估测与分析 ,结果发现 :开产日龄遗传力为 0 .32 4 1,4 0周龄蛋重的遗传力为 0 .3493,体重的遗传力为 0 .4 139～ 0 .4 6 12 ,产蛋量遗传力为 0 .2 5 94～ 0 .3835 ;4 0周龄产蛋量和 72周龄产蛋量之间的遗传相关系数为 0 .5 916 ,开产日龄与72周龄产蛋量间的遗传相关系数为 - 0 .5 94 3,开产日龄与 4 0周龄及 72周龄体重的遗传相关系数分别为 0 .4 2 0 4和 0 .Genetic parameters of major quantitative characters about the fourth generation in strain Ⅲ of Yuzhou egg brown layers were estimated using paternal half sib intra class correlation.The result showed that the heritability of age at first egg,the heritability of 40 week egg weight is 0.324 1 and \{0.349 3\},respectively,the heritability of body weight and the heritability of egg production ranges from \{0.413 9\} to 0.461 2 and from 0.259 4 to 0.383 5;the genetic correlation coefficient of 40 week egg production with 72 week egg production,age at first egg with 72 week egg production is 0.591 6 and -0.594 3,that of age at first egg with 40 week and 72 week body weight is 0.420 4 and 0.797 1.
