摘　　要：对人工仿生栽培的野生樱桃李,按农艺性状、抗逆性状及经济性状多样性,初步筛选了41个优良单株;又对这41个优良单株从果色、可溶性固形物含量、单果平均质量大小、核果比、总酸、单株平均产量6个性状进行了聚类分析,经过综合评比,最后选出4个形态特征优良的品系和11个储备良种的种质资源。Folly-one elite strains of wild Prunus divaricata by bionic cultivation were screened out in terms of agricultural charac- ters, tolerance to environmental stresses and economic characters. A cluster analysis was conducted on fruit color, soluble solid content, average weight per fruit, ratio of stone to fruit, total acidity and average production per tree, and then the elite strains were synthetically evaluated according to the stability of characters in cultivation experiment. Four strains were selected as excellent strains in morphological characters and eleven strains as seed resources.
