Abstract
The shortage of new cannabis varieties with low THC and high CBD content and irregular planting techniques have become the bottleneck for he development of non-psychoactive medicinal cannabis industry. Based on the cannabis germplasm resources, this paper proposes strategies for breeding high CBD content, seed-type and high-efficiency, dwarf non-psychoactive medicinal cannabis varieties through molecular marker development, assisted breeding, genetic engineering breeding and traditional breeding. According to the suitable ecological factors of non-psychoactive medicinal cannabis,the CBD content and grain yield of non-psychoactive medicinal cannabis can be improved by regulating the nutritional structure and illumination properties of non-psychoactive medicinal cannabis,scientific harvesting and storage. At the same time,in order to further accelerate the application of non-psychoactive medicinal cannabis,we can accelerate the selection of new varieties of non-psychoactive medicinal cannabis by mining genetic information of cannabis,and strengthen the application of information technology and automation of modern agriculture in the production of non-psychoactive medicinal cannabis. Provide basis for the cultivation and wide application of new non-psychoactive medicinal cannabis varieties with high quality and high yield.
