The linkage relationship of a nuclear male sterile locus, ms-10, was tested with two enzyme marker loci known to be on the same chromosome (long arm of chromosome 2). The results indicate the gene order is Est-1 - 18 cM - Prx-2 - 1.5 cM - ms-10. The linkage intensity of ms-10 and Prx-2 (1.5 cM) suggests that Prx-2 might provide a selectable marker for male-sterility. In accordance with this idea, the ms-10 allele was placed in cis with a rare-allele of Prx-2 (Prx-2 (1)). Selection on the basis of the codominant Prx-2 (1) allele should allow for more rapid and efficient transfer of the recessive male sterile allele into an array of genetic backgrounds, thus promoting its use in hybrid seed production.
核雄性不育位点 ms-10 与两个已知位于同一染色体（2 号染色体长臂）上的酶标记位点的连锁关系进行了测试。结果表明，基因顺序为 Est-1-18 cM-Prx-2-1.5 cM-ms-10。ms-10 和 Prx-2（1.5 cM）之间的连锁强度表明，Prx-2 可能为雄性不育提供一个可选择的标记。根据这一想法，ms-10 等位基因与 Prx-2 的罕见等位基因（Prx-2（1））位于顺式位置。基于显性 Prx-2（1）等位基因的选择应该能够更快速有效地将隐性雄性不育等位基因转移到一系列遗传背景中，从而促进其在杂种种子生产中的应用。
