To this end, we introduced in 1986 Heilongjiang Academy of Agricultural Sciences and other units of 13 soybean varieties after two years of barley after multiple testing, screening out three varieties, are described below. First, the No. 28 Heinong cited from the Institute of Soybean Research Institute of Heilongjiang Academy of Agricultural Sciences. The variety of summer sowing period of 90 days, plant height of 90 to 80%
