【摘要】 本文用人工接种大豆灰斑病菌的方法对１０８份供试材料，在生理小种水平上进行了抗性鉴定。根据供试材料对灰斑病菌各生理小种的抗感反应，从中筛选出抗８个以上生理小种的材料４６份，占供试材料４２．５％。其中，抗１０个生理小种材料１３份，占供试材料１２．３％更多还原

【Abstract】 soybean varieties (lines) were inoculated separately with 10 races of Cercospora sojina. The main object of the study was to screen out varieties (lines) which were resistant to dominant physiological races and other multiple physiological races of C.sojina Hara. The results were: 46 soybean varieties (lines)were resistant to 8-10 races (42.5% of total tested material). Among them, 13 cultivars were resistant to 10 races.更多还原
