摘要
本研究利用四川白鹅选育测定资料为材料，分析了四川白鹅不同家系的开产日龄、开产体重、50和68周龄产蛋量和蛋重的遗传变异。结果表明：四川白鹅开产日龄为185天，变异系数为11．39%，开产体重为3739．36克，68周龄产蛋量为59．4枚，变异系数为15．87%，68周龄产蛋量和50周龄产蛋量间的相关系数为r＝0．6302。
The genetic variation of age of the first egg. the body weight ofthe first egg, egg production and egg weight of 50 and 68 weeks old of 8differeut families in Sicluan White Geese were anaiysed. The results indlcatedthat age of the first egg, the body weight of the first egg were 185 day and3739. 36g. Coefficient of variation of age of the first egg was 11. 39%. At 68weeks egg producton was 59. 4, Correlation coefficient for egg production between68 and 50 weeks of age was 0. 6302.
