农作物育种的历史证明,一种新的种质资源的发现与研究将给育种工作带来新的突破。水稻矮源基因的发现使水稻产量大幅度提高,被誉为第一次绿色革命。我国杂交水稻研究成功是水稻育种历史上的又一次突破,同样条件下比普通良种增产20%,誉为第二次绿色革命。湖北光周期敏感核不育基因的发现其应用价值在于,将使杂交稻的发展跨入一个新的阶段,它使核基因控制恢复面广,
The history of crop breeding shows that the discovery and research of a new germplasm resource will bring new breakthroughs in breeding. The discovery of rice dwarf gene makes rice yield increased significantly, known as the first green revolution. The success of research on hybrid rice in China is another breakthrough in the history of rice breeding. Under the same conditions, the yield increase of 20% compared with that of ordinary breeds is regarded as the second green revolution. The discovery of Hubei photoperiod-sensitive genic male sterile gene has its application value in that it will make the development of hybrid rice enter a new stage. It will make the control of nuclear gene recover widely,
