摘　　要：草原樱桃具有较强的抗寒、抗旱、抗病虫害性,而对樱是北京当地的中国樱桃品种。为了培育出适合北京及华北地区的抗逆性强的砧木,分别在2005年和2006年将草原樱桃和对樱杂交,共得到17个杂交后代。现采用SRAP技术验证了草原樱桃和对樱的17个杂交后代的杂种真实性。聚类分析结果表明:17个杂交后代的遗传基础更多的来自于草原樱桃。Prunus fruticosa Pall. had the advantages in cold, drought, pest and disease resistance. Prunus pseudocerasus Lind1. cv. Duiying is a Prunus pseudocerasus vairety adaptable to Beijing environment. Hybridizations between Prunus fruticosa and Prunus pseudocerasus （Duiying） were done in 2005 and 2006 respectively to breed stress tolerant cherry stock for Beijing and North China area. Total 17 hybrids were obtained. The truth of the 17 hybrids were identified by SRAP. In addition, cluster analysis results showed that more genetic substances were from Prunus fruticosa than Prunus pseudocerasus in 17 hybrids.
