In China average yield of soybean is 1. 83 t/hm2,it was lower 0. 7~0. 9 t/hm2 than main producer in the world. During the past several years China import annually above 20 ~ 26 million tons. Total annual soybean production was about 27 million tons. Main task for Chinese soybean industry is increasing of soybean production per unit and total production. Breeding on Super- high Yield of soybean is important task for soybean scientists. Through crossing breeding, mutation we developed three cultivars: Zhonghuang 13, Zhonghuang 19 and Zhonghuang 35. Zhonghuang 13 released 224 000 hm2 in 2005 year,it occupied first place in Northern China, and third place in whole China. Ministry of Agriculture of PRC announced Zhonghuang 13 as main soybean cultivar for release in China during 2005~2007 years.
