株两优系列组合烟后制种高产关键技术

Key Techniques for High Yield Seed-Production of ‘Zhuliangyou’ Rice Series Combination as Post Tobacco Rice

摘要: 株1S （原名株6259S）是湖南省株洲市农业科学研究所选育的低温敏两用核不育系。2015-2017年均口镇修竹村引进株两优189、株两优120、株两优173等3个株1S组合作烟后制种，取得较好的经济效益，3年累计制种面积达260 hm²，平均入库种子产量3.52 t·hm²。根据株1S亲本的特征特性，结合当地生产实际，总结株1S系列组合水稻类烟后制种技术。

Abstract: Rice ‘Zhu 1 S’ (6259S as original name) is a dual-purpose thermal sensitive genic male sterile line bred by Zhuzhou Institute of Agricultural Sciences, Hunan Province. From 2015 to 2017 combinations of ‘Zhuliangyou 189’, ‘Zhuliangyou 120’ and ‘Zhuliangyou 173’ were introduced as post tobacco rice for seed production in Xiuzhu Village, Junkou Town, obtaining good economic benefits. The accumulated area of seed production in three years reached 260 hm² and average yield of seed in storage was 3.52 t·hm². Based on characteristics of parents of ‘Zhu 1 S’, the paper summarized its seed production techniques as post tobacco rice.
