中国杂交籼稻育种现状分析及未来主攻方向OA
Analysis of Current Situation and Future Main Research Directions of Indica Hybrid Rice Breeding in China
近年来,中国杂交稻种植面积约 1 700 万 hm2,其中杂交籼稻占比达 97.0％,在中国水稻生产与粮食供给体系中发挥重要支撑作用.持续推进杂交籼稻育种技术创新与品种升级,是提升粮食产能、筑牢国家粮食安全屏障的关键举措,具有重要的现实与战略意义.本文基于 2003-2025 年国家审定的 3 944 个次杂交籼稻品种区域试验数据,系统分析了中国杂交籼稻的育种发展现状,梳理了当前育种工作中存在的突出问题,结合杂交水稻育种实践与产业发展需求,明确了未来杂交籼稻育种的主攻方向,并提出了针对性的策略和建议.
China's hybrid rice has a planting area of approximately 17 million hm2 in recent years,among which indica hybrid rice accounts for 97.0％,playing an important supporting role in China's rice production and grain supply system.Continuously advancing breeding technology innovation and variety upgrading of indica hybrid rice serves as a key measure to enhance grain production capacity and ensure national food security,which possesses important practical and strategic significance.Based on the regional trial data in 3 944 times of national approval of indica hybrid rice varieties from 2003 to 2025,this paper systematically analyzed the current situation and major problems of indica hybrid rice breeding in China.With consideration to breeding practices and industrial development demands of hybrid rice,this paper defined future main research directions of indica hybrid rice breeding and put forward targeted strategies and suggestions.
