ABSTRACT Five recessive and non-allelic genes, ms-1, ms-2, ms-3, ms-4 and ms-5 possessing unique phenotypes govern male sterility in muskmelon. An inbred MS-1, having recessive ms-1 gene, refined at Punjab Agricultural University, Ludhiana (India) has been successfully utilised for the development of commercial F1 hybrids. Since the transfer of a recessive gene is tedious and time-consuming, it is very difficult to incorporate the male-terility gene, ms-1 in different backgrounds. The current study was conducted to construct a simple sequence repeat (SSR) marker-based linkage map for ms-1 locus using F2 population derived from a cross ‘MS-1 // KP4HM-15ʹ. A total of 506 SSR primer pairs was screened followed by bulked segregant analysis (BSA). Linkage analysis of 150 F2 plants mapped three SSR markers, DM0187, DM0038 and TJ14 linked to the ms-1 gene on chromosome 6. The marker, DM0187 was closest to the gene at a genetic distance of 4.8 cM. The identified marker can be effectively used to transfer ms-1 gene into elite muskmelon genotypes through marker-assisted backcross breeding, till more tightly linked markers are available. Further, determination of its chromosomal position will be useful for the fine mapping and also provide a basis for cloning of the gene, ms-1.

甜瓜 (Cucumis melo L.) 核雄性不育基因 ms-1 的分子定位

摘要 五个隐性和非等位基因,ms-1、ms-2、ms-3、ms-4 和 ms-5 具有独特的表型,控制着甜瓜的雄性不育。具有隐性 ms-1 基因的近交 MS-1,在旁遮普农业大学,Ludhiana(印度)精制,已成功用于开发商业 F1 杂种。由于隐性基因的转移既繁琐又耗时,因此很难将雄性不育基因 ms-1 纳入不同背景。进行当前的研究以使用源自交叉'MS-1//KP4HM-15'的F2群体构建ms-1基因座的基于简单序列重复(SSR)标记的连锁图谱。总共筛选了 506 个 SSR 引物对,然后进行批量分离分析 (BSA)。150 株 F2 植物的连锁分析定位了三个 SSR 标记,DM0187,DM0038 和 TJ14 与 6 号染色体上的 ms-1 基因连锁。标记 DM0187 最接近该基因,遗传距离为 4.8 cM。通过标记辅助回交育种,鉴定出的标记可以有效地将ms-1基因转化为优良甜瓜基因型,直至获得更紧密连锁的标记。此外,确定其染色体位置将有助于精细定位,也为基因 ms-1 的克隆提供基础。缩写:BSA,Bulked Segregant Analysis;GMS,基因雄性不育;赔率的对数,LOD;NMS,核雄性不育;PAGE,聚丙烯酰胺凝胶电泳;PCR,聚合酶链式反应;RAPD,随机扩增多态性DNA;SCAR,序列表征扩增区域;SSR,简单序列重复 DM0187 最接近基因,遗传距离为 4.8 cM。通过标记辅助回交育种,鉴定出的标记可以有效地将ms-1基因转化为优良甜瓜基因型,直至获得更紧密连锁的标记。此外,确定其染色体位置将有助于精细定位,也为基因 ms-1 的克隆提供基础。缩写:BSA,Bulked Segregant Analysis;GMS,基因雄性不育;赔率的对数,LOD;NMS,核雄性不育;PAGE,聚丙烯酰胺凝胶电泳;PCR,聚合酶链式反应;RAPD,随机扩增多态性DNA;SCAR,序列表征扩增区域;SSR,简单序列重复 DM0187 最接近基因,遗传距离为 4.8 cM。通过标记辅助回交育种,鉴定出的标记可以有效地将ms-1基因转化为优良甜瓜基因型,直至获得更紧密连锁的标记。此外,确定其染色体位置将有助于精细定位,也为基因 ms-1 的克隆提供基础。缩写:BSA,Bulked Segregant Analysis;GMS,基因雄性不育;赔率的对数,LOD;NMS,核雄性不育;PAGE,聚丙烯酰胺凝胶电泳;PCR,聚合酶链式反应;RAPD,随机扩增多态性DNA;SCAR,序列表征扩增区域;SSR,简单序列重复 通过标记辅助回交育种,鉴定出的标记可以有效地将ms-1基因转化为优良甜瓜基因型,直至获得更紧密连锁的标记。此外,确定其染色体位置将有助于精细定位,也为基因 ms-1 的克隆提供基础。缩写:BSA,Bulked Segregant Analysis;GMS,基因雄性不育;赔率的对数,LOD;NMS,核雄性不育;PAGE,聚丙烯酰胺凝胶电泳;PCR,聚合酶链式反应;RAPD,随机扩增多态性DNA;SCAR,序列表征扩增区域;SSR,简单序列重复 通过标记辅助回交育种,鉴定出的标记可以有效地将ms-1基因转化为优良甜瓜基因型,直至获得更紧密连锁的标记。此外,确定其染色体位置将有助于精细定位,也为基因 ms-1 的克隆提供基础。缩写:BSA,Bulked Segregant Analysis;GMS,基因雄性不育;赔率的对数,LOD;NMS,核雄性不育;PAGE,聚丙烯酰胺凝胶电泳;PCR,聚合酶链式反应;RAPD,随机扩增多态性DNA;SCAR,序列表征扩增区域;SSR,简单序列重复 确定其染色体位置将有助于精细定位,并为基因 ms-1 的克隆提供基础。缩写:BSA,Bulked Segregant Analysis;GMS,基因雄性不育;赔率的对数,LOD;NMS,核雄性不育;PAGE,聚丙烯酰胺凝胶电泳;PCR,聚合酶链式反应;RAPD,随机扩增多态性DNA;SCAR,序列表征扩增区域;SSR,简单序列重复 确定其染色体位置将有助于精细定位,并为基因 ms-1 的克隆提供基础。缩写:BSA,Bulked Segregant Analysis;GMS,基因雄性不育;赔率的对数,LOD;NMS,核雄性不育;PAGE,聚丙烯酰胺凝胶电泳;PCR,聚合酶链式反应;RAPD,随机扩增多态性DNA;SCAR,序列表征扩增区域;SSR,简单序列重复
