| 摘 要： | 在猪的商品生产中，主要是利用品种（品系）间的杂交，但是目前大部分选择方法局限于纯种群，只利用了加性遗传方差，而在杂交生产中起重要作用的非加性方差则没有考虑。基于最终的产品是杂种，要获得杂种性能的最大遗传进展，更为合乎逻辑的方法是将纯种和杂种信息结合选择

| Abstract: | Crossbreeding between breeds or lines is intensively applied in commercial pig production. However, most selection methods are within purebred populations, only exploited additive genetic variances, little attention has been given to the non-additive variances that play an important role in crossbred performance. Based on the fact that final commercial products are crossbred, to obtain a maximum genetic progress in crossbred performance,combining purebred and crossbred information seems to be a logical way. This paper reviews the researches on using crossbred information in pig breeding. |
