【摘要】 研究表明,小麦雪霉叶枯病是豫西地区小麦叶枯类病害中危害最重的一种,目前生产上推广的品种多不抗病,田间发病情况上的差异主要是由于种子和土壤带菌量的有无和多少造成的,小麦属其它物种中有一些植物材料对该病表现高抗,可作为抗雪霉叶枯病育种的抗源材料。更多还原

【Abstract】 The results of study indicate that wheat leaf blight of snow mold has more serious damage than other leaf blights on wheat in western Henan.All of the wheat varieties investigated are showed susceptible to this disease.The status of occurrence of wheat leaf blight of snow mold depend upon the content of the pathogen in the field and on the seed.Some of the plant materials in Triticum were showed to be apparently resistant to wheat leaf blight of snow mold, so they may be good resistance resources for breeding of resistant wheat varieties.更多还原
