以太湖稻区和国内其他地区的39个香稻品种,以及籼型恢复系2个对照品种为研究材料,利用SSR分子标记进行DNA指纹图谱构建和遗传多样性分析。从40对国标中公布的水稻SSR引物中筛选出13对核心引物,在41个水稻品种中共检测到36个多态性片段。据此建立41个水稻品种的DNA指纹图谱,进行聚类分析,发现供试41个品种的遗传相似系数在0.58以上,而供试香稻品种的遗传相似系数在0.64以上,基本反映了不同品种间的亲缘关系。 A total of 39 aroma rice cultivars in the Taihu Lake and other parts of China and two control lines of indica restorer lines were used as materials to construct DNA fingerprinting and genetic diversity analysis using SSR markers. Thirteen pairs of primers were screened from 40 rice SSR primers published in the national standard and 36 polymorphic fragments were detected in 41 rice cultivars. Based on this, DNA fingerprinting of 41 rice cultivars was established and cluster analysis was carried out. The genetic similarity coefficient of 41 cultivars tested was above 0.58, while the genetic similarity coefficient of above indica cultivars was above 0.64, which basically reflected the diversity of cultivars Between kinship.
