摘要:
为了明确陕南地区自交系油菜材料间的亲缘关系,为油菜自交系材料的合理利用、优良杂交亲本选配、提高油菜育种效率提供理论依据,以72份高油油菜自交系材料为试验材料,运用笔者所在实验室筛选的28条多态性高、条带清晰的SCoT引物,进行遗传多样性分析。采用NTSYS-pc2.10e软件中的UPGMA法构建聚类图,用Structure软件进行群体结构分析。结果显示,28条SCoT引物共扩增出327条条带,其中多态性条带为289条,多态性条带占比为88.38%,多态性信息含量(PIC)为0.70~0.94,平均为0.85。Structure群体结构分析与UPGMA聚类结果的一致性较高,说明SCoT标记能有效揭示油菜材料间的亲缘关系。72份油菜自交系材料在遗传相似系数0.64处被分为3类,遗传相似系数主要分布在0.62~0.78之间,占86.85%。表明供试油菜材料间亲缘关系较近,应进一步发掘新的自交系材料,丰富现有油菜材料的遗传多样性,为油菜杂交育种提供优良的遗传资源。
