农作物种子生产程序和种子类别的确立 ,应遵循以育种者种子为种源基础 ,运用重复繁殖技术路线 ,对种子进行限代繁殖等原则 ,以适合中国种子现代化特点 ,并与国际先进技术接轨。建议采用育种者种子→原原种→原种→良种四级程序。并逐步建立以株系循环法技术为基础的保种圃和低温低湿库双重保种制度。
The establishment of crop seed production procedures and seed categories should follow the principles of breeder seed as the provenance basis, application of repeated breeding techniques and limited seed multiplication of seed to suit the characteristics of China’s seed modernization and integrate with international advanced technologies. Proposed breeder seed → original species → original species → seed four procedures. And gradually establish a line of circulation technology-based seedbeds and low-temperature low-humidity warehouse dual seed system.
