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 is Hunan Ao-Long Technology Co., Ltd. Aolong 1S / Y58S F4 generations of excellent male sterile line 535-6-18S as the mother, and widely accounted for 63-4S cross, through the Huaihua in Hunan and Hainan continuous 5 a 10 generations of north-south shuttle plus the planting, the use of natural low-temperature artificial and artificial fertility screening, to strengthen the screening of rice quality, resistance identification and determination of combining ability, bred in 2011 Photo-thermo-sensitive genic male sterile lines. Yunfeng S fertility stability, fertility transition critical temperature is low, breeding, seed production is high, rice better quality, strong resistance, with strong, the combination of resistance to fattening, yield superiority, quality Better. In March 2016, it was approved by Hunan Crop Variety Approval Committee.
