１９９１—１９９３年，在黑龙江省大豆菌核病发生较重的嫩江地区，选择国营农场九三管理局山河农场作为试验基点。在疫区自然感病条件下，评价了８００多份大豆种质资源对菌核病的相对抗性。在年发病率分别为１２．１％、２８．１％和２１．３％的条件下，编号为９１号、１３９号、３０号等９价大豆种质材料，对菌核病表现了相对稳定的抗性。这表明，开展抗病育种研究，利用抗病品种防治大豆菌核病是可能的。试验中发现，田间发病率与气象条件，大豆成熟期，播种密度等因子具有不同程度的相关性。因此，避病特性也是需要考虑的一个方面。
From 1991 to 1993, in Nenjiang area where the sclerotialism of S. Sclerotiorum in Heilongjiang Province was heavy, the Shanhe Farm of National Bureau of Administration of National Farm 93 was selected as the test base. In natural diseased areas, the relative resistance of more than 800 soybean germplasm resources to sclerotinia was evaluated. Under the condition of annual incidence rates of 12.1%, 28.1% and 21.3%, the 9-valent soybean germplasm with No. 91, No. 139 and No. 30 showed relatively stable against Sclerotinia sclerotiorum Resistance. This shows that the development of disease-resistant breeding research, the use of disease-resistant varieties of soybean scab control is possible. The experiment found that the incidence of the field and the weather conditions, soybean maturity, planting density and other factors have different degrees of correlation. Therefore, avoidance characteristics is also an aspect to consider.
