摘　　要：杂交水稻的制种成本高,成为杂交水稻发展与推广的瓶颈。通过混播制种实现杂交水稻制种机械化,可有效降低杂交水稻制种成本。新混优6号母本为携带颖壳褐色标记基因的新安S,父本为携带苯达松敏感基因的2E06,是适合机械化混播制种的杂交水稻新组合。该组合简化了制种程序,节约了制种成本,增加了制种效益。文章介绍了新混优6号的选育过程、特性及其高产栽培技术要点和混播制种技术要点。The high cost of hybrid rice seed production has become the bottleneck of the development and promotion of hybrid rice.The cost of hybrid rice seed production can be reduced effectively by realizing the mechanization of hybrid rice seed production through mixed sowing.Xinhunyou 6 is a new hybrid rice combination suitable for mechanized mixed-sowing seed production.The female parent is Xin'an S with brown glume marker gene and the male parent is 2E06 with bentazon sensitive gene.The combination simplifies the procedure of hybrid seed production,saves the cost and increases the benefit of seed production.This paper introduced the breeding process,characteristics and key technical points of high-yielding cultivation and mechanized mixed-sowing hybrid seed production of Xinhunyou 6.
