利用隐性的矮生基因,培育叶片直立上冲,光能利用率高,抗倒、耐肥,适于密植和间套作的矮秆玉米杂交种,正在成为世界玉米育种的一种发展趋势。 1965年,我所从品种间杂交种“东风1号”(龙门大心×金皇后)的自交后代中发现了矮生植株,并根据生产发展的需要,自力更生地开展了玉米矮秆育种的研究工作。十多年来,在毛主席革命路线的指引下,先后选育出了“矮325”、“矮331”、“龙73”、“杂
Utilizing recessive dwarf genes, breeding dwarf maize hybrids with upright leaves upright, high utilization rate of light energy, anti-down, anti-fertilizer and suitable for close planting and intercropping are becoming a trend of world maize breeding . In 1965, we found the dwarf plants in the selfing descendants of hybrid variety “Dongfeng 1” (Longmen Xinyuan × Jinhuang Queen), and carried out self-reliance on the dwarf breeding of maize based on the needs of production development research work. For more than a decade, under the guidance of Chairman Mao’s revolutionary line, “Dwarf 325”, “Dwarf 331”, “Dragon 73” and “Miscellaneous”
