以普通小麦、四倍体小麦及其各染色体组供体种为母本,与一年生簇毛麦(Haynalida villosa,2n=14)和四倍体多年生簇毛麦(H.hordeacea,2n=14)杂交,研究了小麦属与簇毛麦属的可杂交性。结果表明,乌拉尔图小麦(AA)、拟斯卑尔脱小麦(SS)和节节麦(DD)与一年生簇毛麦的杂交率分别为1.8％、2.4％和82.4％,它们与多年生簇毛麦的杂交率分别为7％、0.8％和38.6％,上述各组合中,除乌拉尔图小麦与两种簇毛麦的组合能产生出正常的种子外,其余四组合所结的种子均不能正常发芽。圆锥小麦与两种簇毛麦的杂交率分别为0.9-8.8％和1.2-19.6％,所结种子大都能正常发芽。圆柱小麦与两种簇毛麦的杂交率分别为1.1％和1.5％,所结种子都不能正常发芽。普通小麦与两簇种毛麦的可杂交性同普通小麦与栽培黑麦的情况相似,它们可能受小麦的同一遗传系统控制。
With the wheat and tetraploid wheat as the female parent, the parents of annual wheat and tetraploid wheat (Hayleyida villosa, 2n = 14) and tetraploid perennial wheat (H. hordeacea, 2n = 14) Hybridization, the crosses between Triticum and Triticella were studied. The results showed that the cross rates of Ural plot wheat (AA), Pei’esi peel wheat (SS) and nodular wheat (DD) were 1.8%, 2.4% and 82.4%, respectively. The crossbreeding rate of wheat was 7%, 0.8% and 38.6% respectively. In the above combinations, the seeds of the other four combinations could not be normal except that the combination of Ural plot wheat and two cluster hay plants could produce normal seeds. germination. The crosses rate of conical wheat and two species of HMCs were 0.9-8.8% and 1.2-19.6% respectively, most of the seeds were sprouted normally. The crossbreeding rates between cylindrical wheat and two species of Himalayan wheat were 1.1% and 1.5%, respectively, and all the seeds were unable to germinate normally. Crossbreeding of Common Wheat with Two Cluster Hirsuts Similar to the case of common wheat and cultivated rye, they may be controlled by the same genetic system of wheat.
