通过对大豆品种间杂交后代在田间发病条件下的连续选择和鉴定，创新了可以抗１０个灰斑病生理小种，兼抗花叶病１号株系的抗病种质东农９６７４。多年多点鉴定和多年接种鉴定表明，东在９６７必高抗灰斑病，抗性稳定，根系发达，固氮能力强、耐重迎茬。是大豆抗灰斑育种和多抗育种的优异种质资源和亲本材料。省内外育种单位作为亲本引用，已作了２０个杂交组合。
Through continuous selection and identification of the cross between the soybean varieties in the field, we developed a new resistant cultivar Dongnong 9674 resistant to 10 gray spot disease physiological races and resistant to Mosaic disease. Years of multi-point identification and identification of many years of inoculation showed that the east of 967 will be high resistance to gray leaf spot, resistance and stability, developed root system, nitrogen-fixing ability, tolerance to cropping. It is an excellent germplasm resource and parental material for soybean resistance to gray spot breeding and multi-resistance breeding. Breeding units inside and outside the province as a parent reference, has made 20 hybrid combinations.
