文摘内容 Genetic relationships between Ziziphus jujuba and Ziziphus spinosa populations were studied using RAPD data in population genetics. 275 loci were gained among which 249 loci were polymorphic by 22 primers. The polymorphic loci percentage was 89% among Z. spinosa population while that of Z .jujuba population was 56%. 31 specific RAPD markers were detected on 3 Z.jujuba varieties and 15 Z. spinosa forms. Cluster analysis showed: when λ = 12, the forms tested were divided into 2 groups. One included Z. jujuba cv. Zanhuangdazao, Yudichuangan, Yuanshichuangan, Xiaochuangan, Qiantai No. 1, Luzhuangchuangan; the other included Z. jujuba cv. Zilingdan and 26 Z. spinosa forms. All above indicated that Z. jujuba and Z. spinosa should be regarded as two separate species。
