New red is selected from the red star varieties spur, red new varieties. Over the past 20 years, no recovery of plants has been found through the primaries, checkups, final decisions and extensive area trials and production appraisals. It has been confirmed that the varietal characters are stable, high quality, high yield and strong adaptability. Dwarf traits, short branch ratio, stability were significantly better than the new red star. For apple short cultivation, will be a good breeding hope good varieties. Currently in the province more than 30 with a city development of nearly mu, Liaoning, Shanxi, Beijing, Tianjin and other more than 10 provinces and municipalities have introduced test planted. 1 Breeding After the new red is in 1973 in Qinhuangdao Beidaihe horticultural field selected red star mutant plants. Due to rot disease, in
