利用小麦的杂种优势来大幅度地提高产量是小麦育种研究工作的重要课题之一。目前国内外采取的途径有:利用提型和非提型的“三系”法及化学杀雄的“两系”法来配制杂交种,以探讨杂交小麦的利用价值和应用前途。我所于一九七二年开展提型杂交小麦的研究, The utilization of wheat heterosis to increase yield is one of the most important topics in the research of wheat breeding. At present, the approaches adopted at home and abroad are as follows: to prepare hybrids by using the “three lines” method of presenting and non-presenting type and “two lines” method of chemical killing, so as to explore the utilization value and the future of hybrid wheat. In 1972, I conducted a research on the type of hybrid wheat,
