| 摘 要： | 野扁桃（Amygdalus ledebouriana Schlecht）为野生珍稀濒危植物资源,我国仅分布在新疆。为研究野扁桃与栽培扁桃及其近缘种的亲缘关系,对新疆野扁桃、栽培扁桃、栽培桃和桃属部分物种的叶绿体matK基因进行测序,基于Kimura 双参数模型计算种间遗传距离,并以邻接法（NJ）构建系统发育树。结果表明：野扁桃与蒙古扁桃和榆叶梅的遗传距离较小,与栽培扁桃和桃属物种（桃、山桃和蟠桃）的遗传距离较大;栽培扁桃与山桃、蟠桃和桃的亲缘关系较其与野扁桃、榆叶梅和蒙古扁桃的亲缘关系更近。

| Abstract: | Amygdalus ledebouriana Schlecht (wild almond) is not only one of the rare wild plant resources, but also an endangered plant species. A. ledebouriana is only distributed in Xinjiang in northwest China. Chloroplast encoding intergenic genes (matK gene sequence) of A. ledebouriana and its sibling species were sequenced to investigate the phylogenetic relationship of wild almond, cultivated almond and the sibling species. Genetic relationship was inferred from the analysis of interspecific genetic distance based on KimurJP8]a’JP]s two parameter model and the neighbor joining (NJ) phylogenetic tree. The preliminary results indicated that there was a closer genetic distance between A. ledebouriana and A. mongolica and between A. ledebouriana and A. triloba, and a further genetic distance between A. ledebouriana and cultivated almond and between A. ledebouriana and the species of subgenus Amygdalus (A. persica, A. persica var. compressa and A. davidiana). Cultivated almond was more closely related to A. persica, A. persica var.compressa and ]A. davidiana than to the three species of almond, i.e. A. ledebouriana, A. mongolica and A. triloba. |
