中新网郑州10月19日电 (李超庆 孙慧敏)河南农业大学19日消息称,经专家实打验收,由该校汤继华团队选育的玉米新品种YD268,在河北省石家庄市藁城区陈家庄120亩玉米示范田里,亩产2083.6斤。
这已是该品种连续第三年测产,亩产均稳定在2000斤以上。科研人员介绍称,2024年,河南鹤壁高产攻关田亩产2365.84斤;2025年,山东济南连续秋雨20多天,仍实现亩产2177.2斤;2026年,河北石家庄气温低、积温少、后期降温快,仍实现亩产2083.6斤。
作为此次测产专家组组长,中国农业科学院作物科学研究所研究员黄长玲表示,从今年田间表现看,YD268群体整齐度好、果穗结实率高,在高密度种植条件下耐密抗逆优势突出,是适宜黄淮海区域推广的耐密高产型品种。YD268团队核心成员李卫华介绍,此次测产地块与当地普通田地管理模式相同,没有额外水肥化控投入,在黄淮偏北积温较低情况下仍实现吨粮水平。
已连续两年参加该品种测产活动的经销商于俊玲说,两年测产所在地气候、年景不一样,“这个品种一次没让人失望,年年都有新底气”。首次试种120亩YD268的种植户贾国良称,地里玉米棒子个头均匀,他基本是常规管理,来年计划带动周边乡亲一块种。河北邯郸种植户韩建军说,YD268株高更矮、果穗均匀、出苗整齐、棵棵有穗,来年也要种植该品种。
品种过硬是底气,模式创新是路径。2024年,河南农业大学探索“科研单位+种业企业+推广渠道”协同模式。三年来,在黄淮海建设4810个示范点,累计吸引百万人次观摩。河南农业大学社会服务处处长赵翠萍表示,科企合作不是简单的品种转让,而是从育种方向、示范布点到推广服务的全链条协同。
“连续三年跨区域实打验收,既验证了YD268广适高产、抗逆稳产的核心优势,也检验了学校精准育种、靶向培优的科研成效。”河南农业大学党委委员、农学院党委书记贾磊表示,学校将继续深化科企合作,推动成果转化,为新一轮千亿斤粮食产能提升筑牢品种根基。
据悉,河南农业大学选育的玉米新品种YD268此前以2680万元人民币完成技术转让,创下国内种业界玉米品种转让费最高纪录。
