近年来,我们在进行大麦育种研究时,为了培育特种类型材料,将开颖开花性状转育到很多育种材料上,这就给大麦黑穗病、大麦条纹病等种传病害的传播带来了方便,每年数以千计的大麦单株和株系,由于被黑穗病感染,不但造成减产,而且造成大量的有益基因丢失,现在生产上用麦病灵等药剂拌 In recent years, when carrying out research on barley breeding, in order to breed special types of materials, we transferred the flowering traits to many breeding materials, which brought about the spread of such diseases as barley smut and barley stripe disease Convenient, each year thousands of barley plants and strains, due to smut infection, not only resulted in reduced production, but also caused a lot of beneficial genes are lost, and now the production of malt extract and other pharmaceutical mix
