我国在完成野败籼稻三系配套以后,杂交水稻在农业实践中发挥了巨大作用.三系的基础理论研究也做了不少工作.截至目前,对控制恢复性能的遗传背景的研究提出了几种看法.最初有人提出“血缘说”;后来,随着对三系材料的深入研究分析,提出了“一对基因说”和“两对基因说”.大多数三系研究者同 After completing the three lines of wild indica rice matching in our country, hybrid rice played a great role in the practice of agriculture.The basic theory of the three lines has also done a lot of work.Up to now, the research on the control of the genetic background of restoration performance Later, with the in-depth study and analysis of the three lines of materials, “one pair of genes” and “two pairs of genes” were proposed. Most of the three lines of researchers
