天安S是湖南奥谱隆科技股份有限公司以Y 58S为母本,与自选较高世代重穗型籼粳交种质材料525-12-56(粳730/抗520//H 262/多系1号)杂交,通过安徽合肥与海南三亚加代种植定向选择、人工与自然低温生态加压育性筛选及加强稻瘟病抗性鉴定等技术途径,育成的早熟型优质抗病光温敏核不育系,2015年参加安徽省光温敏核不育系育性鉴定。天安S具有育性稳定,育性转换临界温度较低,所配组合均具有熟期较早,植株矮壮,茎杆中粗,叶片窄、短、挺直,分蘖力较强,抽穗整齐,后期落色好,且植株较矮,耐肥抗倒力强,田间病虫发生少,作晚稻种植表现耐低温能力较强,结实率较高,产量优势较同熟期主栽品种明显。2016年5月通过安徽省农作物品种审定委员会鉴定。
Tian An S is Hunan Ao-Long Technology Co., Ltd. to Y 58S as the female parent, with the optional higher generation of heavy panicle-type indica and japonica crossbred material 525-12-56 (japonica 730 / anti-520 / H 262 / multi-line 1) were selected to be hybridized. Through the selective selection of Hefei and Hainan Soybean, the artificial selection and selection of low-temperature ecological and fertility fertilization and the identification of rice blast resistance, Department, in 2015 to participate in fertility identification of light-sensitive genic male sterile lines in Anhui Province. Tianan S has stable fertility and low critical temperature of fertility conversion. All the combinations have the characteristics of earlier maturity, shorter plants, thicker stems, narrower leaves, shorter and more straight leaves, stronger tillering ability, Late color loss, and plants shorter, resistant to strong anti-down, field pests and less occurrence of late rice planting performance of low temperature resistant ability, higher seed setting rate, yield advantage over the same period of the main cultivars significantly. In May 2016, it was appraised by Anhui Crop Variety Approval Committee.
