摘要
遗传进展的传递速度是杂交繁育体系建设中的重要问题之一。本文首次提出杂交情况下遗传进展的传递模型，以猪的杂交为例，应用基因流动法，对遗传进展的传递进行了研究。还提出了杂交情况下核心群与商品群遗传时距的计算方法。
The understanding of the rate of disseminating genetic gain from nucleus to commercial herds is an important task in the establishment of crossbreeding system for domestic animals. In this paper,the dissemination models of genetic gain about crossbreeding are presented for the first time. With an example in pig crossing, the dissemination of genetic gain by using gene flow method is investigated.A procedure for calculating the genetic lag between nucleus and commercial herds in crossbreeding system is also proposed.
