| 摘 要： | 从来自不同地理区域的36个樱桃基因型中筛选了33对不同樱桃品种的微卫星引物,以鉴定和描述他们的基因型并确定亲缘关系。33对微卫星引物中,29对获得了预期的扩增片段,17对引物在所研究的36个基因型中产生了多态性高、稳定扩增片段,17个位点共检测到71个等位基因。微卫星分子标记技术可以准确的鉴别所有樱桃品种的基因型,为微卫星序列的通用性提供强有力的证据,可以用蔷薇科李属的序列来区分樱桃品种的不同基因型,根据不同品种的地理起源及其亲缘关系用UPGMA聚类分析法对其基因型进行分类。

| Abstract: | A collection of 36 cherry genotypes from diverse geographic areas were fingerprinted with 33 microsatellite primer pairs developed in different species of Prunus in order to identify and characterize the genotypes and establish their genetic relations.29 of these primer pairs produced meaningful amplifications and 17 produced polymorphic repeatable amplification patterns among the 36 genotypes studied.A total of 71 alleles were detected for the 17 loci.All the genotypes studied could be unequivocally distinguished with the combinations of the microsatellite markers used.The results provided evidence for cross-species applicability of microsatellite sequences,which allows the discrimination of different genotypes within a fruit species with sequences developed in other species.UPGMA cluster anlaysis of the similarity data was used to group the genotypes in respect to their geographic origin and/or their pedigree information. |
