著名杂交水稻育种专家袁隆平提出了杂交水稻育种分为三个发展阶段的战略设想,即:三系法品种间杂种优势利用,两系法亚种间杂种优势利用和一系法远缘杂种优势利用。“一系法”即利用无融合生殖法固定水稻品种间及更远缘的强大的杂种优势。这既是人们愿望,也是杂种优势育种发展的 Yuan Longping, a famous expert on hybrid rice breeding, put forward the strategic assumption that hybrid rice breeding is divided into three stages of development: utilization of heterosis among three lines, heterosis utilization of two lines of subspecies and utilization of heterosis of distant branches . The “One Line Approach” is the use of apomixis to establish strong heterosis between rice varieties and more distantly. This is both the aspiration of people, but also the development of heterosis breeding
