摘　　要：N111S是用培矮64S作母本,安农S-1作父本进行有性杂交,通过加压筛选,定向培育而成的不育起点温度低、综合性状好、配合力强、外观米质好的水稻两用核不育系,2006年通过湖南省农作物品种审定委员会审定,2014年通过安徽省农作物品种审定委员会鉴定。所配组合N两优1号(N111S/9311)先后通过湖南省和安徽省农作物品种审定委员会审定。Derived from the cross of Pei＇ai 64S/Annong S-1, N111S is a photoperiod- and thermo-sensitive genic male sterile （PTGMS） line in rice with low critical sterility-inducing temperature, high combining ability and good grain appearance quality. It was registered by Hunan Provincial Crop Variety Appraisal Committee in 2006, and technically identified by Anhui Provincial Crop Variety Appraisal Committee in 2014. Its hybrid N Liangyou 1 （N111S/9311 ） was registered and released to commercial production by Hunan and Anhui provincial crop variety appraisal committees in 2007 and 2015, respectively.
