摘　　要：以小麦根腐病菌００２号菌株产生的致病毒素（ＨＳＷ－毒素）为选择剂，选用春、冬小麦品种、品系以及杂种的花药和幼穗进行离体培养，并结合物理诱变技术，已获得抗根腐病的植株，用根腐病菌分生孢子接种鉴定。おおhe fungal filtrate prepared from the cultures of H. sativum train No. 002 was used as the screening agent. The anther and young inflorecences from varieties, strains and hybrids of spring and winter wheat were cultured in vitro. The calli were treated with physical mutagens. Finally the mutants resisting to H. sativum were obtained. Out of 50 regenerated plants resisting to fungal filtrate, 12 plants were resistant when put them to inoculation test with conisiospore of H. sativum.
