摘要: 对福建省农业科学院亚热带农业研究所自育品种(系)和常规对照种进行SCoT分析,探讨甘蔗品种间的亲缘关系。结果显示:15条SCoT引物对23份供试材料扩增总共得到122个可分辨的清晰条带,平均每条引物产生8.1个条带,其中多态性条带69条,多态性比率为56.56%;聚类分析后发现23份甘蔗品种存在较小的遗传差异,相似系数为0.77~0.98,说明育种亲本来源相近,重复利用多,遗传多样性不丰富。

Abstract: Molecular marker technique of SCoT was applied to analyze the genetic diversity of the sugarcane varieties (or lines) bred at Fujian Academy of Agricultural Sciences, along with the conventional cultivars for comparison. Establishment of the genetic relationship among the germplasms provided the needed reference for breeding and identification of the existing resource. Fifteen SCoT primers were selected to amplify the genome DNAs of 23 test materials. A total of 122 loci, with 56.56% of them polymorphic, were obtained averaging 8.1 bands detected by each primer. A clustering analysis revealed a minute genetic difference existed among 23 sugarcane varieties with a similarity coefficient ranging from 0.77 to 0.98, indicating a close relationship in origins of the breeding parents, duplicated applications, and low genetic diversities among the cultivars.

Key words: sugar cane, bred varieties, SCoT, genetic diversity
