由于大麦是具有2n=2x=14染色体的二倍体自花授粉作物,其染色体较大而且形态容易区别,所以广泛地用于遗传研究。以大麦为材料,可在同一处理群体中根据细胞遗传学和遗传学观点同时测定化学和物理诱变剂的效应。变剂处理种子或植株后,出现叶色分离的突变体表现型,这类突变体通常叫做叶绿素缺变体。按照 Gustafsson(1940)的分类,包括白化、黄化、浅绿、条纹和斑点。叶绿 Because barley is a diploid self-pollinating crop with 2n = 2x = 14 chromosomes, it is widely used in genetic studies because of its large chromosome size and easy morphological differentiation. Using barley as a material, the effects of chemical and physical mutagens can be simultaneously determined in the same treatment population based on cytogenetics and genetics. After treatment of seeds or plants with a variety of agents, mutant forms of leaf color separation appear, and such mutants are often referred to as chlorophyll deficient. According to the classification of Gustafsson (1940), including albino, yellow, light green, stripes and spots. Green leaves
