Zusammenfassung: | The invention discloses wheat blue and abortive sterile germplasm and a breeding method thereof and belongs to the field of wheat breeding. The blue and abortive sterile germplasm with high stems and stable sterile characters is obtained through the steps of selecting high-stem sterile plants from a blue, dwarf and abortive backcross group with stable transformation, sorting blue seeds of the high-stem sterile plants and planting, and continually carrying out backcross by using original male parents. Substantially, three linked genetic characters including blue, dwarf and abortive characters are subjected to character exchange so that a chain relation with dwarf-stem marker genes is broken through; meanwhile, late-heading and late-maturing characters with a negative effect are also eliminated; anther abortive germplasm still with blue grain marker characters is obtained; two character genes including blue grains and anther abortion have linked heredity. The germplasm gas good stability, and does not need to b |
