报道了大麦籽粒原花色素缺失突变体的筛选技术及遗传分析结果,用10~(-3)M叠氮化钠处理干种子,收取M_2代籽粒,用香萆醛-盐酸试剂进行单籽粒非破坏性检测,筛选突变体并加代稳定。研究表明,突变体为单基因隐性,并可发生在不同的基因位点。此外,探讨了突变体的改良和应用途径,认为无原花色素大麦不仅可在啤酒工业中产生显著效益,其饲用价值也有所改良。
The screening technology and genetic analysis of the proanthocyanidin-deficient mutants of barley grain were reported. The seeds were treated with 10-3M sodium azide and the seeds of M_2 were collected. The seeds of the seeds were treated with the sangria aldehyde-hydrochloric acid reagent Destructive testing, screening of mutants and plus stable. Studies have shown that mutants are single recessive and can occur at different genetic loci. In addition, we discussed the ways of improvement and application of mutants. It is concluded that proanthocyanidin-free barley not only produces significant benefits in the beer industry, but also has an improved feed value.
