13%、为普通玉米的 1.6 倍以上，创下湖北夏玉米蛋白含量新纪录。该品种聚合高蛋白位点、耐夏播高温，省区域试验平均亩产 533.76 公斤，审定后以 2000 万元实现成果转化。企业实行「蛋白每高一百分点就加价」，收购价达 2420 元\u002F吨、较普通玉米每吨溢价百元。","（洪图新、李维、蒋艳艳）2026年9月13日，湖北省农业科技服务支点建设“五大提质行动”暨高蛋白玉米新品种“未玉115”现场观摩会在麻城市举行。\n\n湖北省农业科学院专家组对当地200亩示范田开展实收测产，蛋白质含量达13%，为普通玉米的1.6倍以上，平均亩产644.1公斤，创下湖北夏玉米蛋白含量新纪录。\n\n“这个品种穗筒形，⽩轴⻩粒，硬粒型，蛋⽩含量达13%，是普通⽟⽶的1.6倍以上。”品种选育⼈、湖北省农科院粮作所专家、副研究员张⼠⻰掰开⼀个穗⼦说，“未⽟115”聚合⾼蛋⽩位点，耐夏播⾼温，省区域试验平均亩产533.76公⽄，9⽉12⽇⽰范⽅⾥机收测产644.1公⽄\u002F亩。⽽且，⽐普通夏⽟⽶多出的不只是⽄两，还有蛋⽩“附加值”。籽粒加⻘贮，粗略算“⼀亩两笔”⽐单卖粮划算。\n\n普通玉米蛋白含量仅7%左右，想要同时拉高蛋白和产量，是育种领域一大难关。省农科院副研究员张士龙介绍，玉米祖先大刍草天然粗蛋白可达30%，现代育种长期侧重高产，高蛋白基因逐步丢失。湖北夏播环境高温高湿，锈病、灰斑病多发，极端天气频发，育种团队需要同时兼顾高蛋白、高产量、强抗逆三重目标。\n\n“掰开棒子，籽粒密实饱满，连玉米穗尖都长满籽粒，几乎没有空壳花粒。”麻城市禾旺青稞种植专业合作社理事长冯其珍拿着刚收获的玉米，语气满是赞叹。\n\n该品种湖北省农科院选育，历经13年科研攻关育出，2025年正式通过品种审定。今年黄冈进行区试。6月，在黄冈市农科院专家指导下，麻城市禾旺青稞种植专业合作社试种200亩“未玉115”。经历台风大风倒伏考验，又遭遇持续高温、锈病高发天气，周边不少玉米地块黄叶倒伏、空粒减产，这片示范田依旧青枝绿叶，抗倒伏、抗病、耐高温的特性充分显现，被种植户称作既优质又“耐造”的新品种。\n\n科研人员构建两组高蛋白杂交优势群体，通过海量组配筛选，历经13年田间观测淘汰无数组合，终于选育出这一优良杂交种。实现高蛋白与高产协同突破。\n\n不只停留在试验田里，“未玉115”正在打通从种源到大田、再到饲料企业的全产业链。该品种审定后，以2000万元实现成果转化。企业创新实行“蛋白每高一百分点就加价”的议价收购机制。目前，武汉普通玉米挂牌价2300元\u002F吨，高蛋白“未玉115”收购价达到2420元\u002F吨，每吨实现百元溢价。企业已和12家种植主体、2家饲料企业签下合作协议。\n\n这颗湖北玉米种子，瞄准的是我国饲料蛋白供给的现实难题。我国是全球最大饲料生产消费国，2024年大豆进口量突破1.05亿吨，进口依存度超80%，饲料蛋白供给高度依赖进口大豆。业内测算，如果全国玉米蛋白普遍提升5个百分点，新增蛋白供给约等同于3500万吨大豆蛋白，可降低超三成大豆进口需求，相当于节约耕地2.1亿亩，直接压低养殖生产成本。\n\n观摩现场，不少黄冈本地种植大户表现出强烈扩种意愿。麻城市乾丰农业科技有限公司总经理雷中厚表示，对比风险高、储运难的鲜食玉米，高蛋白饲料玉米销路稳定，希望后续可以大面积改种该品种，稳保种植收益。\n\n本次观摩会由湖北省农科院粮作所、黄冈市农科院组织，设置育种、栽培、智慧种植、产业化专题报告，50多名黄冈种植大户现场观摩学习。\n\n黄冈市农科院涂军明介绍，推广高产高蛋白玉米新品种“未玉115”，既能帮助农民增产增收，也能减少豆粕进口依赖，把国人肉盘子、奶罐子牢牢攥在国产种子手中，对筑牢粮食安全防线，提升产业链供应链自主可控能力具有重要意义。（完）\n\n特别声明：以上内容(如有图片或视频亦包括在内)为自媒体平台“网易号”用户上传并发布，本平台仅提供信息存储服务。","网易
