Breeding of High-yield Clones in Cultivation of Medicinal Plants
药用植物培养高产细胞系的选育

It is an effective means to tap the resources of medicinal plants by the way of fermenting plants to obtain the secondary metabolites of useful medicinal plants. Nevertheless, most of useful secondary matters are extremely low in the cells of plants. For this reason, people have to first breed and improve the cells of plants in order to increase the content of secondary matters in industrialized production. This article summarizes the breeding methods and research of high -yield clones of medicinal plants and purposefully discusses the problems, such as the screening of high - yield clones, mutation breeding and gene transfer and the study of key techniques and its solution of the instability of high - yield clones.
