摘　　要：盐220S系江苏沿海地区农科所在广占63S群体中发现1株天然变异株后经多代系谱选择而育成的籼型光温敏核不育系,2013年通过江苏省农作物品种审定委员会鉴定。江苏沿海地区农科所以盐220S为母本与盐恢888配组育成的高产优质两系杂交籼稻新组合盐两优2208,于2013年通过国家农作物品种审定(国审稻2013026)。Yan 220S, derived from a natural variant plant discovered among the population of Guangzhan 63S and developed by Jiangsu Agricultural Research Institute for Coastal Regions through pedigree selection over years, is an indiea photo- and thermo-sensitive genie male sterile （PTGMS） line in rice. In 2013, it was technically identi- fied by Jiangsu Crop Variety Appraisal Committee. Its hybrid Yanliangyou 2208 （Yan 220S/Yanhui 888 ） , a new two-line hybrid rice combination with high yield and good grain quality, was subsequently developed and released for commercial production by the National Crop Variety Appraisal Committee in 2013.
