摘　　要：33S是湖南省水稻研究所选育的晚稻专用水稻温敏核不育系,具有株型理想、不育起点温度低(<23℃)、异交习性好等优良特性,2012年通过湖南省农作物品种审定委员会审定,2016年获得国家植物新品种权授权。截至2022年,利用33S配制的杂交组合已有36个通过了省级以上品种审定,其中15个品种通过国审。33S所配组合株型紧凑,适应性广,品质优良,产量较高,且对病虫害具有一定抗性,2015—2021年在湖南、江西和湖北三省的推广面积超过128.22万hm^(2),对保障长江中下游双季稻生产具有重要意义。33S is a thermo-sensitive genic male sterile(TGMS)line special for late hybrid rice developed by Hunan Rice Research Institute.It has excellent characteristics such as ideal plant type,low critical sterility-inducing temperature(<23 C)and good outcrossing habits.It was registered by Hunan Crop Variety Appraisal Committee in 2012,and granted the plant new variety rights in 2016.As of 2022,36 hybrid combinations derived from 33S had passed the varietal approval at or above the provincial level,of which 15 ones had passed the national varietal approval.The hybrid combinations of 33S have good plant type,wide adaptability,fine grain quality,high yield and certain resistance to diseases and insect pests.From 2015 to 2021,the planting area of the 33S series of hybrid combinations in three provinces of Hunan,Jiangxi and Hubei exceeded 1.2822 million hectares,which is of great significance for ensuring double-cropping rice production in the middle and lower reaches of the Yangtze River.
