To evaluate and utilize potentially valuable quantitative trait loci or genes of wild relatives in the genetic background of domesticated crop species, chromosome segment substitution lines (CSSLs) are a valuable tool. CSSLs can be constructed through the exchange of chromosome segments of AA genome species of the genus with cultivated rice, L. Here we report the development of three sets of CSSLs carrying segments of AA genome species closely related to - (IRGC 103777 from Mali), (W1962 from China), and (IRGC 105715 from Cambodia)-in the genetic background of ssp. cultivar Taichung 65 through the use of 101 to 121 simple-sequence-repeat markers in whole-genome genotyping and marker-assisted selection. The materials are available via the National Bioresource Project (Rice) Oryzabase Web page.
为了评估和利用驯化作物物种遗传背景中野生近缘种潜在有价值的数量性状位点或基因,染色体片段代换系(CSSLs)是一种有价值的工具。通过将该属AA基因组物种的染色体片段与栽培稻L.进行交换,可以构建CSSLs。在此,我们报告了通过在全基因组基因分型和标记辅助选择中使用101至121个简单序列重复标记,在粳稻品种台中65的遗传背景下,开发出携带与-(来自马里IRGC 103777)、-(来自中国W1962)和-(来自柬埔寨IRGC 105715)密切相关的AA基因组物种片段的三组CSSLs。这些材料可通过国家生物资源项目(水稻)的Oryzabase网页获取。
