小麦品种对赤霉病的抗性在作物抗病育种中,很少应用绝对抗性,而着重利用抗病性的材料。事实上,对赤霉病免疫的小麦品种也极为罕见。在抗病品种中,如“鄂麦6号”和“万年2号”,经多数地区鉴定为抗病;但湖南黔阳地区农科所鉴定为感病,这与各地区的病原种类和小麦种的差异有关。因此在抗病育种中,既要重视作物的抗病基因,也要考虑病菌的致病基因。施罗德(H.W.Schroeder)把小麦品种对赤霉病的抗性分为两种类型:抗侵染品种;抗扩展品种。两者仅在程度上有所差异。一 Resistance of wheat cultivars to Fusarium head blight In crop disease-resistant breeding, the use of absolute resistance is seldom applied, and the use of disease-resistant materials is emphasized. In fact, wheat varieties that are immunized against scab are also extremely rare. Among the resistant varieties, such as “Emai 6” and “Wannian 2”, which were identified as resistant to disease in most areas; however, the Agricultural Science Institute of Guizhou Province in Qiangyang County of Hunan Province was identified as susceptible to diseases, Differences in wheat species related. Therefore, in disease-resistant breeding, it is necessary to pay attention to crop disease resistance genes, but also consider pathogenic bacteria genes. H.W. Schroeder classifies the resistance of wheat cultivars to scab as two types: anti-infective varieties; anti-expansion varieties. The two differ only in degree. one
