Abstract: Twenty-nine single segment substitution lines (SSSLs) with the recipient, Taichung 65 and the donor, Dee-geo-woo-gen or Zhaiyeqing had been developed through simple sequence repeat (SSR) marker-aided selection. The total length of substituted segments in 29 SSSLs was 643.65 cM with an average of 22.19 cM; the total covered length was 427.55 cM on nine chromosomes with the coverage of 23.47% of rice genome.

Key words: rice, single segment substitution lines, simple sequence repeats, molecular marker-aided selection

摘要： 利用微卫星标记辅助选择，建立了29个以台中65为受体、低脚乌尖或窄叶青为供体的单片段代换系，该代换系群体的代换片段分布于9条染色体上，总长度为643.65 cM，平均长度为22.19 cM，覆盖全基因组427.55 cM，覆盖率为23.47%。
