摘要
籼型光温敏核不育系F133S是以1892S为母本、R3061为父本杂交，经过6年12代定向低温加压系谱选择而成，该不育系起点温度低、育性稳定、败育彻底、株型好、穗多、抗性较好、抗倒、米质较优、配合力强、异交结实率高，2013年通过安徽省农作物品种审定委员会组织的技术鉴定。该研究介绍了F133S的选育过程、特征特性，以期进一步推广运用该不育系。
Abstract
Derived from the cross of 1892S(as the female) and R3061(as the male),F133S is a new photo-thermo-sensitive genetic male sterile line in Indica rice.It was bred after six years and 12 generations of directional selection under the condition of low temperature stress .F133S showed the characteristics of low critical temperature , complete and stable male sterility,panicles with many spikelets, good blast resistance, good grain quality, high combining ability and favorable outcrossing habits .F133S was certified by Anhui Provincial Crop Variety Release Com-mittee in 2013.In this research, breeding process and characteristics of F133S were introduced, aiming at further popularizing and applying this variety.
