摘要

Oil-bearing roses are a type of aromatic plant in genus Rosa, which have a complex genetic relationship in China. In this research, we applied matK sequence variations to examine the genetic relationship among 37 oil-bearing roses grown in China. Results showed that oil-bearing roses mainly formed two clades, A and B. Clade A were divided into two subclades, A1 composed of Rosa sertata 脳 Rosa rugosa and Rosa davurica, and A2 composed of most rugosa cultivars, which are consistent with the classification of section Cinnamomeae in 鈥楩lora of China鈥? R. 鈥楾ujue鈥? R. 鈥楬ongshuangxi鈥? R. 鈥楤aojialiya Hong鈥? R. 鈥楬ezeyang鈥? R. 鈥楥rimon Glory鈥?and R. 鈥楤aojialiya Bai鈥?clustered B1. Some Gallicanae cultivars introduced from abroad clustered B2. B1, B2 and some fragrant wild species including Rosa odorata var-gigantea, Rosa multiflora var. cathayensis, Rosa rubus, R. rugosa were classified in clade B, which indicates that there may be introgression of the wild species in the formation of the oil-bearing cultivars in B1 and B2.
