Abstract Vegetable soybean is mainly planted in south of China. Seven cultivars introduced from home and abroad were planted on May 1,8,20,in order to select vegetable soybeans suitable for planting in Harbin area. Growth stage structure,yield related traits including fresh pod mumber（FPN） ,fresh pod weight（FPW） ,fresh seed weight（FSW） and 100-fresh seed weight （HFSW）, seed quality traits such as soluable sugar content,fat content and protein content were measured. Planting date had significant effect on FPN,FPW,FSW and HFSW. Sapporomidoh got the highest fresh pod yield （14 897.50 kg·ha~(-1)） when planted on May 20,then was Taiwan 292 （13 006.50 kg·ha~(-1) ） planted on May 1. Sapporomidoli got the highest protein content planted on May 1 while Taiwan 292 on May 8. Soluable sugar content of Sapporomidoli and Taiwan 292 maxmized when planted on May 20 and May 1 ,respectively,while fat content of the two cuhivar all maxmized when planted on May 8. According to yield and quality performance, Sapporomidoli and Taiwan 292 are suitable to plant in Harbin.
