摘　　要：用仙湖3号鸭第九世代A系核心群40个家系192只母鸭的个体产蛋数据资料进行相关分析。结果:开产体重(x)与初生蛋重(x1)、36周龄蛋重(x2)之间,初生蛋重(x1)与36周龄蛋重(x2)之间均呈强的直线正相关。母鸭150天产蛋数(y)与开产体重(x)之间呈曲线相关,拟合的一元二次方程为y=-457.6630+315.7595x-42.2932x2,拟合度为0.9746,拟合效果很好。提示:采用限制饲养控制仙湖3号鸭开产体重在3.5～3.7kg可获得较理想的产蛋数。Dataonegglayingof192femaleducksintheninthgenerationofXianhu3ducksAstrainwereusedtoanalysethecorrelationbetweentheeffectofbeginninglyingweightandpartoflayingperformances.Resultsshowedthat,thereisasignificantpositivelinearcorrelationbetweenthebeginninglayingweightandweightofthefirsteggs,theweightof36weekeggs,andbetweenweightofthefirsteggsandtheweightof36weekeggs.Thecorrelationbetweenthebeginninglayingweightandtheeggquantityduring150dayswereofcurvecorrelation,thecurveequationwasy=-457.6630+315.7595x-42.2932x2,thegoodnessoffitis0.9746.Sotheidealeggproductionwouldbeachievedwhenthebeginninglayingweightswererestrictedfrom3.5kgto3.7kgfortheXianHu3Duchs.
