| 摘 要： | 为了探讨梅(Prunus mume Sieb.et Zucc.)的2种类型--花梅与果梅的遗传多样性,利用23条长度为11bp的随机引物以及严格筛选退火温度的改良RAPD-PCR优化体系对25个花梅和21个果梅品种的基因组总DNA进行了分析,并在此基础上采用UPGMA聚类方法对46个花梅与果梅品种间的遗传关系进行了分析.结果显示:使用重复性好、条带清晰且多态性强的23条随机引物,共从46个花梅和果梅品种基因组总DNA中扩增出131条带,其中多态性条带107条,多态性条带百分率达81.7%,说明花梅和果梅各品种间具有丰富的遗传多样性.聚类分析结果显示:46个花梅和果梅品种的遗传相似系数为0.63～0.83;在遗传相似系数0.66处,供试的46个品种被分为5组.A组包含6个果梅品种和11个花梅品种;B组仅包含4个花梅品种;C组包含16个品种,其中15个品种为果梅;D组仅包含4个花梅品种;E组也仅包含5个花梅品种.研究结果表明:花梅和果梅具有相近的亲缘关系,遗传背景相似.

| Abstract: | In order to explore the genetic diversity of two types of Prunus mume Sieb.et Zucc.,which are flowering and fruiting mei,total genomic DNA from 25 cultivars of flowering mei and 21 cultivars of fruiting mei was analyzed by modified RAPD-PCR optimized system with strict screening of anneal temperature and using 23 random primers with the length of 11 bp.And on this basis,the genetic relationship of 46 cultivars of flowering and fruiting mei were analyzed by UPGMA cluster method.The results show that 131 band... |
