用Khapli与遗传背景不同的小麦杂交,能够将一至二个抗白粉病性基因传递给杂种后代。特别是与“绵阳11号”、郑州761”;早熟“阿波”和“大粒早”等品种杂交,在对白粉病菌4、16、20号小种抗性遗传分析时多呈3:1,15:1的分离比例,表明Khapli有一至二个显性抗病基因传递给杂种后代。但对64号小种的抗性遗传分析则出现了一至二对隐性基因传递给杂种后代,同时也说明Khapli与不同遗传背景的普通小麦杂交后,在抗性基因传递上不能将三个抗病性基因全部传送给杂种后代。
Crossing Khapli with wheat of a different genetic background can deliver one or two genes for powdery mildew resistance to hybrid offspring. Especially with “Mianyang 11”, Zhengzhou 761 “; early maturity” Apoloon “and” big grain early "and other varieties of hybrids, the powdery mildew 4,16,20 race resistance analysis of genetic analysis were mostly 3: 1,15 : 1, indicating that Khapli has one or two dominant resistance genes passed on to the offspring, but one or two pairs of recessive genes were transmitted to the offspring by resistance genetic analysis of race 64. In addition, After hybridization between Khapli and common wheat with different genetic backgrounds, all three disease resistance genes can not be transmitted to hybrid offspring on resistant gene delivery.
