The invention discloses a breeding method of a white grain and blue grain partial waxy near-isogenic line of a wheat variety, which comprises the following steps: by utilizing a blue-dwarf-male-sterile AB double-group waxy and partial waxy transformation technology system, after several rounds of backcross, sorting white grains from a group A, selfing for two generations, homozygous and stable waxy genes, selecting a single ear seed ear row, and performing molecular marker-assisted selection on the ear row, thereby obtaining the white grain and blue grain partial waxy near-isogenic line of the wheat variety. Various types of partial waxy near-isogenic lines of the original variety are obtained; a white grain group sorted from the group A is a mixed group of a waxy and partial waxy near-isogenic line of an original backcross variety, and commercial food produced by field planting of the white grain group has a quality effect similar to that of waxy wheat flour; searching non-dwarf plants with anther in the gro
