1027 soybean germplasm were screened and evaluated for resistance to root rot,caused by Phytopththora sojae.The results showed that the resistance of Chinese soybean germplasm was better than that of introduced ones;The germplasm from south of China was higher resistant to root rot than north ones; The germplasm from Yangtze River Basin was highest resistant,the germplasm from Yellow River,Huaihe River and Haihe River Basins was higher and the Northeast ones were low.The resistance of breeding lines was better than cultivars and landraces and there were different in resistance in the germplasm from different provinces,of which Heilongjiang germplasm was lowest resistant to Phytophthora root rot.It was one of the important causes of occurrence of Phytophthora root rot in the Province.There were more resistant germplasm in colorless,yellow and brown color types of seed navel.
