小麦近缘属种纹枯病的抗性鉴定

Identification of Resistance to Wheat Sharp Eyespot in Wheat Relatives

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。

accessions of relatives and 3 cultivars of wheat were screened for resistance to wheat sharp eyespot by inoculation.The results showed that 5 accessions from relatives of wheat were immune to wheat sharp eyespot;12 accessions were highly resistant to wheat sharp eyespot,5 accessions were medium susceptible,and only A.aquarrosa 34×Yumai 9 was highly susceptible to wheat sharp eyespot.
