Efficient corn breeding method based on single plant evaluation and whole genome selection technology

The invention discloses an efficient corn breeding method based on a single plant evaluation and whole genome selection technology. The method comprises the following steps: S1, performing multi-male-parent pollen pollination on a corn female parent in a first planting season; S2, performing single-seed sowing and single-plant selection on the hybrid seeds in the second planting season, and evaluating target characters; S3, identifying the selected hybrid combination parents; S4, performing whole genome prediction on target characters of the hybrid combination; S5, selecting an excellent hybrid combination according to the predicted target character; and S6, enabling the selected excellent hybrid combination to directly enter a variety certification link or continues to be evaluated. According to the breeding method provided by the invention, the seed quantity of the first planting season hybrid combination assembly and the planting scale of the second planting season hybrid combination are greatly reduced, t
