在日本,由于抗大麦条纹萎缩病的抗性品种的相继育成,目前已有15个啤酒大麦品种大面积栽培。与此同时一些过渡性品种(系)也大量涌现。农户往往未能认真区分品种,将一品种误认作它品种,产生“抗性品种染病”的疑虑。这就迫使我们需迅速采取对策,帮助他们识别品种。识别品种有各种各样的方法。有在特定的限制性酶中将品种的全DNA消解得到限制性片段多态性(RFLP)图谱来识别品种的;也有通过品种蛋白质电泳图谱差异识别的;另外
In Japan, 15 barley varieties of beer have been cultivated on a large scale due to the successive breeding of resistant varieties resistant to barley stripe atrophy. At the same time, some transitional varieties (lines) have also emerged in large numbers. Farmers often fail to carefully differentiate breeds and misidentify a species as its breed, creating the suspicion of “resistance breeds”. This forces us to take prompt measures to help them identify breeds. There are a variety of ways to identify breeds. There are restriction fragment polymorphisms (RFLP) patterns that are obtained by digesting the entire DNA of a variety of species in a specific restriction enzyme to identify the species; others are also differentially identified by the electrophoretic pattern of the species; in addition
