DNA marked-assisted selection of medicinal plants accelerated the breeding and promotion of new cultivars, and guaranteed the healthy development of Chinese medicinal materials industry. The first disease-resistant cultivar of notoginseng, namely "Miaoxiang Kangqi 1", served as the object of study. We evaluated the Kangqi's resistance of seeds, seedlings and root against the pathological bacteria (Fusarum oxysporum) of root rot. Compared to the traditional cultivars, the disease index of notoginseng seeds declined by 52.0% after inoculation for seven days; the death rate of seedlings and disease index of root respectively decreased by 72.1% and 62.4% after inoculation for 25 days. Additionally, the growth inhibition ratio of notoginseng seeds and seedlings declined after inoculation. The seeds, seedlings and roots of "Miaoxiang Kangqi 1" showed significantly resistant to root rot. The evaluation of disease-resistance of Kangqi provided the basis for the popularization of new cultivar and guaranteed the favoring conduct of notoginseng pollution-free cultivation.
药用植物的DNA标记辅助选择加速了新品种的选育和推广，保障了中药材产业的健康发展。以三七首个抗病品种“妙香抗七1号”为研究对象，评价了“抗七”种子、种苗和根对根腐病病原菌（尖孢镰刀菌）的抗性。与传统品种相比，三七种子接种7天后病情指数下降了52.0%；接种25天后，种苗死亡率和根病情指数分别下降了72.1%和62.4%。此外，三七种子和种苗接种后生长抑制率下降。“妙香抗七1号”的种子、种苗和根对根腐病表现出显著抗性。“抗七”抗病性评价为新品种推广提供了依据，保障了三七无公害栽培的顺利进行。
