用土壤接种法对２６份小麦近缘材料、栽培品种及其杂交后代的抗纹枯病性能进行了鉴定。结果表明，小麦近缘植物中存在着丰富的抗纹枯病资源，其中有５份材料表现免疫，他们是节节麦３４、峨观草、野燕麦、八倍体小黑麦、六倍体小黑麦；有１２份材料表现高抗，他们是斯卑尔脱小麦、峨观草（河南）、圆锥小麦、密穗小麦、二棱大麦、阿比西尼亚小麦、节节麦３４×Ｂ１８６、波兰小麦、六棱大麦、硬粒小麦、四棱小麦、茹可夫斯基小麦；有５份材料表现中抗，他们是波斯小麦、东方小麦、节节麦２８×冀麦５４１８、印度圆粒小麦、节节麦２８；只有节节麦３４×豫麦９号为高度感病。
Soil resistance was used to identify the resistance to sheath blight of 26 wheat accessions, cultivars and their progenies. The results showed that there were abundant resources for resistance to sheath blight in wheat relatives. Among them, five materials were immunized, and they were Zongjiemai 34, Emerald grass, wild oats, octagonal tritium, hexaploid Triticale; 12 materials showed high resistance, they are Spelled wheat, Emerald grass (Henan), cone wheat, dense wheat, two barley, Abyssinia wheat, section wheat 34 × B186, Polish wheat, hexagonal barley, durum wheat, quadrangular wheat, and Rokovsky wheat. Five of the materials showed moderate resistance. They were Persian wheat, Oriental wheat, Zaimai 28 × Ji Ma 5418, Round grain wheat, wheat knot section 28; section McKinsey 34 × Yumai 9 is highly susceptible.
