摘　　要：用父系半同胞组内相关法对豫州褐壳蛋鸡Ⅰ系第四世代的主要经济性状的遗传参数进行了研究,结果表明,其遗传力分别为开产日龄0 454,开产蛋重0 181,40周龄蛋重0 3047,体重0 303～0 436,产蛋量0 139～0 182;开产日龄、40周龄产蛋量与72周龄产蛋量间的遗传相关系数分别为-0 2832和0 9252,开产体重与40周龄和72周龄体重之间遗传相关系数分别为0 6784和0 5011.Genetic parameter of major economic traits of four generation in strain I of Yuzhou brown egg layers were studied using paternal halfsib intraclass correlation,the result showed that the heritability of age at first egg,of egg weight at first egg,and of average egg weight is 0454, 0181 and 0304 7,respectively,and heritability of body weight and of egg production ranges from 0303 to 0436 and from 0139 to 0182;the genetic correlation coefficient of age at first egg, 40_week egg production with 72_week egg production is -0283 2 and 0925 2 respectively,that of body weight at first egg with 40_week and 72_week body weight is 0678 4 and 0501 1 respectively
