[Objective] To select the high-quality variety of Glechoma longituba (Nakai) Kupr., and to offer preparations for the large-scale cultivation and structure adjustment of the planting industrialization of Chinese medicinal materials. [Method] After three years' cultivation in Anshun Vocational and Technical College and in Shuangbao Town of Xixiu District in Anshun City, G. longituba from three different areas of Sichuan, Jiangxi and Anshun were transplanted in Drug Garden of Anshun Vocational and Technical College in 2008. Comparative tests on the cultivation were conducted, in order to investigate the plant growth, flowering, stems and leaves growth speeds, yield per plant, medicinal content and so on. The suitable variety of G. longituba for Guizhou Province was selected. [Result] Flowering habits of G. longituba in three areas were basically the same. The flowering periods were all in early spring, and lasted relatively long. The flowering seasons of G. longituba in Sichuan and Anshun were 4-7d longer than that in Jiangxi. The vegetative growth per plant and yields per plant of G. longituba growing in three different areas were in the order of Sichuan﹥Anshun﹥Jiangxi; yields and medicinal contents were in the order of Sichuan﹥Anshun﹥Jiangxi. [Conclusion] Due to its high yield and high quality, Sichuan G. longituba is the main extension variety in Guizhou Province at present. If the varieties having strong resistance to leaf spot could be selected from Anshun G. longituba, the yield could enhance greatly; and Anshun G. longituba could become an ideal variety for extension.
