摘    要:阐述了玉米近交衰退的理论基础,强调了加性遗传效应对杂种优势的作用以及穗部性状的配合力与产量的相关性,分析了系谱法不同世代家系的测交产量与家系世代的关系。提出了采用系谱法与家系内小群体轮回选择相结合的选育方法,并从S3家系开始进行家系内轮回选择和选育高产、高配合力玉米自交系的技术方案。

关 键 词:玉米  配合力  自交系  系谱法  轮回选择  专论

Abstract:Based on the inbreeding depression of maize inbred lines, this review addressed the additive effects of gene on heterosis and the correlation between yield and yield components, and analyzed the variation of yields among test crosses of lines in different selfing generations. A methodology that combining the pedigree selection and recurrent selection within the families initiated as early as in S3 was proposed to develop maize inbred lines with high yield and high combining ability.
Keywords:Maize(Zea mays L  )  Combining ability  Inbred lines  Pedigree methods  Recurrent selection  Review
