摘要: 现代畜牧业生产中,利用杂种优势可降低生产成本,挖掘种质资源的内在潜力,提高经济效益。在一些畜牧业发达的国家,肉用仔鸡几乎全是杂种。正是由于杂种优势在畜禽生产上的大规模应用,杂种优势的研究一直受到高度重视。作者在畜禽杂种优势理论基础上,从遗传距离法、线粒体混合试验法、蛋白质分子多态性、群间方差与群内方差之比法及分子标记法等方面综述了畜禽杂种优势测定和评估方法的研究进展,并简要、客观的分析了各方法的优缺点。

Abstract: Based on the theoretical basis of heterosis, this article reviewed the research progress of forecasting animal heterosis from genetic distance, mixed experiment of mitochondrion, protein polymorphisms,ratio of between-group variance to inter-group variance and molecular genetic marker, then analysed the merits and demerits of these methods.
