【摘要】 高油玉米育种从40年代开始，一直未曾间断，但在80年代之前进展不大。种质资源的匮乏和创造资源的艰难是两个基本原因。高油玉米的遗传增值表现在能量水平的提高和营养成分的改善，主要反映在较高的饲养效率和加工产值。80年代以来，随着种质资源的拓宽和育种技术的改进，高油玉米已经走上了健康快速发展的道路，我国高油玉米也从引进资源阶段步入了独立发展新时期。十几年来，无论在资源创新和杂交种选育均有所建树。新育成的杂交种不仅含油量居世界前列，而且在抗病、抗倒及丰产潜力方面均有突破。它把优质、高产、多用途和高效益有机结合起来，因而发展前途十分光明。更多还原

【Abstract】 High oil corn hreeding has started since the late 1940s, but it developed slowly until1980s. The shortag of germplasms and the difficulhes of creating the new germplasms have been the twomain obstacles. It was overeome gradually through the technique improvement and the bnding efforts.The acmp of high oil corn hybrids has been inced quickly in recent yeaes. The added Value benefitsof high oil com in increased enery level and other nutritional compoents reflected mainly in the gain to - feed - ratio of livestheks, poultries and the pmeessing products.High oil com breeding in China has been also gning to the new Peried hath in the germplasm creation and hybrid development. Newly developed hybrids not only the oil content nahed the highest levelof the world conunroialized hybrids, but also realed the beakthough in the field of disease resistance,standability and yield poential. It combined superior quality, yield potential, wide uses and high benetstogether harmoniously, so the foture must be very bright.更多还原
