摘要

特优航2号系福建省农科院水稻研究所用龙特甫A为母本与恢复系航2号选配的晚稻杂优新品种。2011年引进在江苏省现代农业综合开发示范区制种，2a制种平均产量稳定在3.0t/hm2以上。介绍了特优航2号在苏中地区的高产制种技术。%Teyouhang 2, a new late hybrid rice combination, derived from the cross of a CMS line Longtepu A and a restorer line Hang 2, was developed by Rice Research Institute of Fujian Academy of Agricultural Sciences. It was introduced to produce hybrid seeds by Jiangsu Province Modern Agricultural Comprehensive Development Demonstration District in 2011, showing a mean yield of more than 3.0 t/hm2 in two years. Its high-yielding seed production techniques in the middle district of Jiangsu province were introduced.
