Sixteen soybean cultivars were selected from the three northeastern provinces and Inner Mongolia.These cultivars were sown at eight period, and effects of different sowing dates on agronomic characters and yieldof soybean were analyzed. This study provided a guideline for the choice of cultivars in emergency for Tieling. Re-sults showed that different varieties could be chosen at different sowing time. We can choose‘Changnong 17’,‘Suinong 26’,‘Jiyu 93’and‘Jiyu 47’when sowing on May 18 th,‘Jiyu 93’when sowing on May 28 th,‘Hei-nong 51’,‘Suinong 26’,‘Suinong 28’and‘Jiyu 47’when sowing on June 17 th,‘Jiyu 93’,‘Heinong 51’,‘Suinong 26’and‘Jiyu 47’when sowing on June 27 th,‘Hefeng 50’,‘Jiyu 47’,‘Suinong 26’and‘Hefeng47’when sowing on July 7th.
