摘　　要：In 2006, the indica photoperiod- and thermo-sensitive genic male sterile （PTGMS） line Yan 161S was successful y bred by crossing the Guangzhan 63S （♀） and the medium indica breeding material Yan 229 （♂）, which was bred by the Institute of Agricultural Sciences in Coastal Region of Jiangsu Province, after years＇ and generations’ selection in different areas. It passed the identification by Jiangsu Provincial Crop Variety Appraisal Committee in 2013. Crossing the Yan 161S with Yanhui 888, a new high-yielding and high-quality two-line hybrid rice combination Yanliangyou 1618 was developed, and it passed the variety identification in 2014. This paper introduced the breeding processes and characteristics of Yan 161S and Yanliangyou 1618 and the cultivation and seed production techniques of Yanliangyou 1618.江苏沿海地区农科所以广占63S为母本,用自育优质中籼稻中间材料盐229为父本进行杂交,并经多年多代异地选择,2006年育成籼型光温敏不育系盐161S,2013年通过江苏省农作物品种审定委员会鉴定。用盐161S与盐恢888配组育成的优质高产抗病两系杂交水稻新组合盐两优1618,2014年通过江苏省农作物品种审定。介绍了盐161S和盐两优1618的选育经过、特征特性及盐两优1618的栽培、制种技术要点。
