摘要: 研究不同樱桃品种的亲缘关系,为樱桃的引种栽培提供理论依据。以7个樱桃品种为研究对象,利用改良CTAB进行DNA提取,通过PCR进行RAPD扩增,对7个樱桃品种进行DNA多态性分析和RAPD产物的相似系数统计和聚类分析。通过20个随机引物的筛选,发现多态性效果较好的有4个引物,获得了100个DNA扩增片段(120~2 000 bp),表现出明显的多态性,多态率达到87%。UPGMA聚类分析结果表明,7个樱桃品种分为4类,黄果实MZ为一类,黑果实BLA为一类,深红果实AM、RED为一类,EBF、mSUM、SUM为一类。亲缘关系最远的是BLA和MZ,相似系数为0.400,亲缘关系最近的是SUM和mSUM,相似系数为0.990。

Abstract: In order to study the phylogenetic relationships among different cherry varieties and provide theoretical basis for the introduction and cultivation of cherry, RAPD amplification of seven varieties of cherries was performed by PCR. The DNA polymorphism of 7 cherry varieties and the similarity coefficient were analyzed by cluster method of RAPD products. Through the screening of 20 random primers, 4 primers with good polymorphism were found and 100 DNA amplification fragments were obtained, showing obvious polymorphism. The rate of polypeptide was 87%. Based on UPGMA cluster analysis, the tested cherry varieties can be classified into 4 types: MZ with yellow fruit, BLA with black fruit, AM and RED with dark red fruit, and the last catogary of EBF, mSUM and SUM. The kinship between BLA and MZ was the farthest with 0.400 similarity coefficient, while SUM and mSUM were the closest in kinship with 0.990 similarity coefficient.
