As one of the important wild relatives of wheat,some studies have showed that the 1E and 7E chromosomes of Thinopyrum elongatum have FHB resistance genes,which has been considered to be one important germplasm resource for wheat genetic improvement. In order to break the narrow limitation of germplasm resources for wheat 's FHB resistance breeding and enrich its genetic stocks,Chinese Spring-Thinopyrum elongatum disomic substitution line,DS7 E /7A,was used to transfer the FHB resistance genes into common wh...
赤霉病(Fusarium head blight,FHB)是危害小麦(Tritieum aestivum)、大麦(Hordeum vulgare)等多种禾谷类作物的重要病害之一,随着全球气候变暖及耕作制度、耕作方式的变化,其造成的经济损失日益严重,利用抗赤霉病品种减轻其危害已成为育种学家的共识。目前,在小麦种质资源中已?
