高异交率水稻籼型温敏核不育系Z913S的选育

摘要

Z913S,derived from the hybrid cross of Xin'er S/Aizi S(1892S/Zihui 100),is a thermo-sensitive genic male sterile (TGMS) line in rice developed by Institute of Rice Research,Anhui Academy of Agricultural Sciences.In this paper,the breeding procedure of Z913S was ex-plained,and characteristics of Z913S were introduced,including fertility performance,agronomic traits,flowering habits,rice quality.The key tech-nical points of its multiplication and hybrid seed production were analyzed .%Z913S是安徽省农业科学院水稻研究所用新二S与矮紫S(1892S/紫恢100)杂交选育而成的高异交率水稻温敏核不育系.阐述了Z913 S的选育经过,介绍了其特征特性,包括育性表现、农艺性状、开花习性、稻米品质,分析了繁殖制种技术要点.
