本世纪六十年代,国际玉米小麦改良中心育成一系列矮秆半矮秆小麦品种,在许多国家获得增产,成为“绿色革命”的重要组成部分。然而,各地育种者在小麦矮化育种中,遇到了矮秆材料病重、成熟晚和早衰等问题,限制了产量的进一步提高。如何解决这些问题,国内外的育种工作者进行了不少探索,现对各种问题的解 In the 1960s, the International Maize and Wheat Improvement Center bred a series of dwarf semi-dwarf wheat varieties, which increased production in many countries and became an important part of the “green revolution.” However, breeders in various parts of the country dwarfed breeding encountered dwarf disease, serious problems such as late and premature aging, limiting the further increase in yield. How to solve these problems, breeders at home and abroad have carried out a lot of exploration, and now the solution to various problems
