Abstract: In order to select the suitable high altitude cultivated varieties of raspberry, the paper screened four raspberry varieties at high altitude and analyzed the nutrition composition of raspberry. The results showed that the soluble solid content, reducing sugar, total sugar and other nutrients of the same variety gradually increased with altitude from high to low. But the content of vitamin C decreased gradually. The higher the temperature, the higher the total sugar content it had. The content of soluble solids and reducing sugar of Chilcotin blackberry was highest, and the taste was best in the four species. It was suitable for planting in high altitude area. The Fall Gold fruit period was long and taste was moderate. But it was easily broken and not easily transported. It was suitable for processing and growing around in the environs of the city.
