Abstract

Flowering time is an important agronomic trait for crops, and previous breeding work in has successfully transmitted other important agronomic traits from donor species. However, there has been no previous attempts to produce hybrids replacing the original alleles with alien alleles. In this paper, we introduce the creation of a chromosome substitution line (CSSL) containing a homozygous introgression of Flowering Locus C from () into a genomic background, and characterize the CSSL line with respect to the parental cultivars. The preferential transmission of alien chromosome inheritance and the pattern of transmission observed during the production of the CSSLs are also discussed.

摘要

开花时间是作物的一个重要农艺性状，之前的育种工作已成功地从供体物种传递了其他重要农艺性状。然而，此前尚无将外来等位基因取代原始等位基因来培育杂种的尝试。在本文中，我们介绍了一种染色体代换系（CSSL）的创制，该代换系在基因组背景中含有来自（）的开花位点C的纯合渗入，并根据亲本品种对该CSSL系进行了表征。还讨论了外来染色体遗传的优先传递以及在CSSL系培育过程中观察到的传递模式。
