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% 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.
