摘要: 对我国芍药的27个栽培品种和5个近缘种选用了21个性状进行了聚类分析, 结果表明, 5个野生种中, 芍药( Paeonia lactiflora) 与栽培芍药的遗传距离最近; 其次是草芍药( P. bovata) 、美丽芍药( P. mairei) ; 川赤芍( P. veitchii) 、块根芍药( P. anomala) 与栽培芍药的遗传距离则最远, 说明栽培品种与芍药的亲缘关系最近, 而与川赤芍、块根芍药的亲缘关系则最为疏远。该结果与比较形态学研究的结果一致。

Abstract: With selected 21 morphological characters, cluster analysis for 27 Chinese cultivated herbaceous peonies and 5 wild specieswas performed. The result was showed by dendrogram. According to the increasing order of the genetic distance coefficient between certain species and the cultivars, the 5 species were arranged as Paeonia lactif lora, P. obovata and P. mairei, P. veitchii and P. anomala. These results suggested that P. lactiflora had the closest genetic relationship with cultivars, then P. obovata and P. mairei, while P. veitchii and P. anomala had the farthest relationship with cultivars. The conclusion was identical with that of the comparative morphology.
