Chang Fu 2 coloring system (commonly known as Red Fuji) is one of Fuji Apple’s budding strains. According to the data from Japan in 1979, there are 58 strains of buds in Fuji, of which 9 strains perform well and Chang-Fu 2 is one of them.

In order to provide the basis for the production and application, in the past two years, except for our site, and 10 units in 4 districts and 7 counties in Shandong Province, we investigated their high affinity and growth results. The preliminary results are summarized as follows.
