【摘要】 苹果梨是梨属中优良的抗寒种质资源,但关于其分类地位一直存在争议。利用AFLP分子标记技术对其进行研究,通过聚类分析和遗传相似系数分析,重点探讨了苹果梨在DNA水平上的分类地位,认为将苹果梨归为白梨系统较为适宜。更多还原

【Abstract】 Ping guo pear is an excellent germplasm resource of Pyrus with cold resistance.But its taxonomic status is always in dispute.Ping guo pear was studied by using AFLP molecular marker technique.The taxonomic status of Ping guo pear at DNA level was emphatically discussed by clustering analysis and genetic similarity coefficient analysis.It was thought that it was suitable for classifying Ping guo pear to white-pear system.更多还原
