The invention discloses a biotechnological breeding method for overwintering functional rice. The method includes the following steps: S1. selecting overwintering crops as donors; S2. selecting wild rice as a parent body; S3. extracting the DNA of the donors; S4. introducing the DNA of the donors into the parent body; and S5. collecting distant hybrid seeds of the parent body in step S4. The method can greatly improve the yield of rice, has an overwintering function, and can be added with medicinal functions and the like. The method belongs to functional hybrid rice, and as the rice can overwinter, the yield can further be increased. 本发明公开了一种越冬功能水稻的生物技术育种方法，包括下述步骤：S1：选取越冬作物作为供体；S2：选取野生稻作为母体；S3：提取供体的DNA；S4：将供体的DNA导入母体；S5：收集步骤S4母体的远缘杂交种子。能够大幅度提高水稻的产量，具有越冬功能，并且可以附加药用功能等。属于功能性杂交水稻，并且由于能够越冬，所以产量也能够增大。
