袁隆平先生利用野生稻的败育型细胞质基因育成不育系,而笔者则首创了直接利用野生稻细胞核基因选育恢复系的新途径。笔者介绍了直接利用野生稻杂交选育恢复系的技术路线及方法,该法利用野生稻作为主体亲本,与多个各具有显著特点的恢复材料杂交,充分利用野生稻抗性强、适应性广、米质优等特点。采用“大群体多世代”的育种方法成功育成强优广谱性恢复系测253,并育成一系列高产、优质、多抗的新组合。笔者还介绍了测253及其配组组合的应用和产生的社会效益。
Mr. Yuan Longping used aborted cytoplasmic genes of wild rice to generate CMS, and the author pioneered a new way to directly utilize the nuclear gene of wild rice to restore the line. The author introduced the direct use of wild rice hybridization breeding line of technology and methods, the method of wild rice as the main parent, with a number of distinct characteristics of the restorer hybrid material, make full use of wild rice resistance, wide adaptability , High quality and other characteristics of rice. Breeding method with “large population and multiple generations” successfully bred a strong broad-spectrum restorer line 253 and developed a series of new combinations with high yield, high quality and multi-resistance. I also introduced the test 253 and its combination with the application and the resulting social benefits.
