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 halfsib intraclass correlation,the result showed that the heritability of age at first egg,of egg weight at first egg,and of average egg weight is 0454, 0181 and 0304 7,respectively,and heritability of body weight and of egg production ranges from 0303 to 0436 and from 0139 to 0182;the genetic correlation coefficient of age at first egg, 40_week egg production with 72_week egg production is -0283 2 and 0925 2 respectively,that of body weight at first egg with 40_week and 72_week body weight is 0678 4 and 0501 1 respectively
