[Development direction of molecular breeding of medicinal plants]

To breed new varieties of medicinal plants with high resistance is the premise to ensure the production of high-quality medicinal materials. Molecular breeding using modern molecular biology and genetic technology can save time and effort and realize rapid and accurate breeding. Here we are trying to summarize the difference of breeding characteristics between medicinal plants and crops such as genetic background and breeding purpose. The strategy of molecular breeding of medicinal plants was summarized, and the four-phases breeding based on high-throughput sequencing and target gene mining was emphasized. We put forward the current molecular breeding of medicinal plants in the condition of four phases breeding is the optimal technological way of breeding, and gene editing breeding is the direction of medicinal plants breeding.
