摘　　要：云峰S是湖南奥谱隆科技股份有限公司以奥龙1S/Y58S的F4代优良不育株系535-6-18S为母本,与广占63-4S杂交,通过湖南怀化和海南三亚连续5 a 10代的南北穿梭加代种植,利用自然生态低温和人工低温育性筛选,加强米质筛选、抗性鉴定和配合力测定,于2011年育成的光温敏核不育系。云峰S育性稳定,育性转换临界温度低,繁殖、制种产量高,稻米品质较优,抗逆性较强,配合力强,所配组合耐肥抗倒、产量优势明显、米质较优。2016年3月通过湖南省农作物品种审定委员会审定。Yunfeng S, developed by Hunan Opulent Technology Co. Ltd. in 2011, is a photoperiod-thermo-sensi- tive genie male sterile line （PTGMS） in rice. It was derived from the cross of 535-6-18S（ an elite F4 male sterile line from Aolong 1S/Y58S）/Guangzhan 63S and bred through shuttle breeding in both Huaihua, Hunan and San- ya, Hainan for 10 generations over five years, selecting on sterility under low temperature in both natural and artifi- cially controlling conditions, and more attention being paid to the selection in grain quality, resistance and combi- ning ability. Yunfeng S shows stable male sterility yield in multiplication and hybrid seed production, high combining ability for its F1 hybrids performing ance. In March, 2016, it was registered by Hunan with low critical temperature relatively good grain quality on fertility alteration, high seed and strong stress tolerance, and high yielding potential, good grain quality and lodging resist- Crop Variety Appraisal Committee.
