摘要

The invention relates to a seed selection method of self-pollination and cross-pollination agronomic crop, wherein said method comprises: crossing mother group and father group to obtain rice group, while the mother group is obtained by crossing the parental generations with different target characters to generate F1 generation to cross again, and each single one of generated separated group will autocopulate to generate separated single one; the father group selects pure kinds of separated generation. And the inventive method comprises: crossing, stably autocopulation, testing, classifying and group improvement. The inventive seed has consistent, stable, and specific.
