The results showed that different southernwood cultivars displayed different artemisinin contents, especially, the artemisinin contents of planting cultivars and the cultivars with coloured stem were higher. Further AFLP analysis indicated that a specific fragment was amplified respectively with the primers of EA04-MC05 and EA01-MC01. According to the differentia fragments, we clustering analyzed the 10 major kinds of southernwoods by utilizing WPGMA approach. However, there was no distinctly relativity between the artemisinin contents and diversity of AFLP analysis and just can distinguish, southernwood of Youyang county from Shapingba and Beipo in producing area which still illuminated that the heredity differentia of southernwood presented itself obviously in different area.
