Abstract:: 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
