"扬麦53"的成功培育，离不开高德荣团队的攻坚。出生于江苏兴化农村的高德荣，少年时看着父辈辛勤 劳作却难获丰收，便暗下决心学农育好种。2012年小麦赤霉病大暴发的场景，让他至今难忘："试验田 外，大片麦田穗部发红腐烂，农民蹲在田埂上抹眼泪，那种无助的眼神，让我更加坚定了攻克赤霉病的 决心。" "这里本是弱筋小麦优势区，蛋白质合成和积累先天不足，要培育中强筋品种，就得靠技术创新'另辟蹊 径'。"高德荣说，"扬麦53"从亲本组配开始，选育历时15年，若追溯其亲本"扬麦17"的培育历程，更是 跨越30余载。种业振兴行动实施的这5年，也是"扬麦53"品种攻关的关键期。团队摒弃传统经验育种模 式，应用分子标记辅助育种技术，用"精准育种"破解"抗病与丰产、优质难兼顾"的困境。 在国家小麦育种联合攻关试验中，"扬麦53"连续4年赤霉病抗性达R级，参加生产试验平均每亩比对照 增产10.13%，用实打实的表现证明了抗逆与丰产可以"并行"。 "扬麦53"的选育推广，是我国小麦新品种创新成果的一个生动缩影。近年育成的"郑麦1860""中麦 6032""济麦5198""马兰1号"等小麦新品种单产高，正在加快推广；节水品种"衡麦29" ...
