Toona sinensis is one of the precious timber tree species in China, known as mahogany in China. Toona tomentosa is a Endemic Tree Species in China. It mainly occurs in Sichuan, Guizhou, Fujian and Anhui. It is vertically distributed in the range of 500-2500m above sea level. Toona sinensis and Toona tomentosa are not widely distributed in China, and they are sporadic in nature. They are over-exploited and naturally regenerated slowly. The number of Toona sinensis and Toona tomentosa decreases continuously, but their development potential is great. In recent years, more and more domestic scholars have carried out extensive research on Germplasm resources, genetic structure, plant physiology, breeding, cultivation, afforestation, medicine and chemical composition, and resource protection of Toona sinensis and Toona tomentosa in view of their excellent variety characteristics and the fact that they are facing endangerment. This paper combines the research progress of Toona tomentosa and Toona sinensis as a supplement to the related research of Toona sinensis of the same family and genus.
