Abstract

[Objectives] To analyze the genetic similarity among varieties of Armeniaca vulgaris Shushanggan in Ili. [Methods] The genetic distance among 13 A. vulgaris Shushanggan varieties was compared at the DNA molecular level, and clustering analysis was performed on them. [Results] The 13 varieties of A. vulgaris Shushanggan were classified into four clusters. The first cluster included Shushang Ganxing 1, Shushang Ganxing 4, Gongliu Yexing and Zhenzhu Youxing, and the similarity coefficient between Shushang Ganxing 1 and Shushang Ganxing 4 reached 0.808; the second cluster were Shushang Ganxing 2, Shushang Ganxing 3 and Liguangxing, and the similarity coefficient between Shushang Ganxing 2 and Shushang Ganxing 3 was 0.846[1]; Ili Baixing, 61 Tuan Guyexing, Chaxian Yexing and Huocheng Yexing were classified into the third cluster, and the similarity coefficient between Ili Baixing and 61 Tuan Guyexing was 0.692; and the fourth cluster included Shushang Ganxing W1 and Yixian Yexing, between which the similarity coefficient was 0.692. [Conclusions] This will lay a foundation for the research of variety identification and genetic structure of A. vulgaris Shushanggan.
