摘要:

爽两优132是湖南杂交水稻研究中心用爽1S与爽恢32配组选育的优质两系杂交水稻组合,2020年通过国家农作物品种审定委员会审定。2022年9月21日,中国科学院、福建省农业科学院等单位相关专家对爽两优132组合在福建省建宁县的制种示范片进行现场考察和测产验收,产量达6 886.05 kg/hm2,实现杂交水稻制种大面积产量突破。概述了该组合父母本的高产制种特征,总结了爽两优132的高产制种技术要点,为杂交水稻生产制种提供指导。

Abstract:

A high-quality two-line hybrid rice combination Shuangliangyou 132 was bred by Hunan Hybrid Rice Research Center derived from the cross between Shuang 1S and Shuanghui 32, which was approved by the National Crop Variety Approval Committee in 2020. On September 21, 2022, experts from Chinese Academy of Sciences, Fujian Academy of Agricultural Sciences and other units conducted investigation and production measurement on the seed production demonstration area of Shuangliangyou 132 in Jianning County, Fujian Province, and the yield reached 6 886.05 kg/hm2, achieving a large-scale yield breakthrough in hybrid rice seed production. This paper summarized the characteristics of the male and female parent of the combination, and the key points of high-yield seed production techniques of Shuangliangyou 132, which provided guidance for seed production.

Key words: hybrid rice, Shuang 1S, Shuangliangyou 132, seed production technique
