| description | The invention discloses a method for constructing a waxy blue, dwarf and male-sterile alternate selection group and breeding waxy hybrid wheat. The method comprises the following steps: S1, establishing a waxy blue, dwarf and male-sterile alternate selection group with various characters; s2, selecting a test variety complementary with the marker character of the alternate selection group, and transforming the test variety into a waxy near-isogenic line and a blue, dwarf and male waxy backcross group thereof by utilizing an A and B double-group waxy transformation technology; s3, selecting and matching waxy wheat hybrids by utilizing the blue, dwarf and abortion of the tested blue, dwarf and abortion waxy backcross group and the waxy white grains of the complementary alternate selection group; s4, establishing a waxy filial generation test cross strain yield comparison nursery, and selecting a selected strain according to combining ability. The method has the advantages that the comprehensive level of a waxy |
