鉴定了“中国春”小麦及有关染色体缺体-四体系、中国地方小麦品种“白火麦”及国内外400多份品种（系）的Waxy蛋白亚基类型，并从中筛选出43份不同的Waxy蛋白亚基缺失类型材料，特别是筛选出3份Wx－D1亚基缺失类型材料；分析了二倍体小麦、四倍体小麦和原始六倍体小麦（西藏小麦）的Waxy蛋白带型，进一步明确了在小麦的进化过程中，染色体4AL上的片段曾与7BS发生过相互易位，使原来在7BS上的荷载有Wx－B1基因的片段易位到4AL上；初步探讨了PCR技术在小麦Wx基因鉴定中的应用和Waxy蛋白亚基缺失类型的遗传机理。
The Waxy protein subunit types of “Chinese Spring” wheat and its related chromosome deficiency-quaternary system, Chinese local wheat variety “Baihuomai” and more than 400 domestic and foreign cultivars were identified and 43 different Waxy protein subunit deletion type material, in particular, selected three Wx-D1 subunit deletion type material; analysis of the diploid wheat, tetraploid wheat and the original hexaploid wheat (Tibetan wheat) Waxy protein bands, It was further clarified that during the process of wheat evolution, the fragment on chromosome 4AL had been translocated with 7BS, resulting in the translocation of the fragment carrying Wx-B1 originally on 7BS to 4AL. Application of Wheat Wx Gene Identification and Genetic Mechanism of Waxy Protein Subunit Deletion Types.
