| 中文摘要: |
| 粤农丝苗是一个丰抗优综合性状优良的常规优质稻品种，该品种丰产稳产性好，稻米品质优，高
抗稻瘟病和中抗白叶枯病，适应性广。自 2011 年通过广东省农作物品种审定以来，粤农丝苗已先后通过海南、
广西、湖北、江西、湖南、安徽和河南等省（区）审定和引种备案，并作为早晚兼用型优质稻、一季中稻、再
生稻、直播稻及虾稻等广泛推广应用。对粤农丝苗的特征特性研究表明，粤农丝苗收获指数较高、抗倒力强、
后期结实熟色好，具有广谱抗稻瘟病抗性，是新一代的高收获指数品种。同时，粤农丝苗（即恢复系 R1212）
也是一个很好的育种亲本，以其为亲本育成并通过国家、省级审定或授权的水稻新品种已有 37 个，其中常规稻
10 个、杂交稻 27 个，这些品种均表现为优质、高产稳产、适应性好，体现了粤农丝苗作为优良亲本的“芯”片
作用，并作为试验材料广泛应用于栽培、生理等基础理论研究。粤农丝苗自 2012 年起成为广州市优质稻主导品种，
2013—2021 年连续 9 年被遴选为广东省农业主导品种，在华南地区和长江中下游地区具有极其重要的生产价值。 |
| 英文摘要: |
| Yuenongsimiao is a conventional high-quality rice variety with excellent comprehensive characters of highyielding, disease resistance and good-quality. It has high and stable yield, excellent rice quality, high resistance to rice
blast and medium resistance to bacterial blight, and extensive adaptability. Since it was approved by Guangdong Province
in 2011, Yuenongsimiao has been approved and introduced in Hainan, Guangxi, Hubei, Jiangxi, Hunan, Anhui and Henan
Provinces. It is widely used in grain production as both early and late high-quality rice, single cropping medium rice,
ratooning rice, direct seeding rice and shrimp-rice. The studies on the characteristics show that Yuenongsimiao has high
harvest index, strong lodging resistance, good late ripening color and high seed setting rate, broad-spectrum resistance to
rice blast, and was a new generation of high harvest index variety. Yuenongsimiao（i.e. restorer line R1212）is also as an
excellent breeding parent, with which 37 new rice varieties have been bred and passed national and provincial approval or authorization, including 10 conventional rice varieties and 27 hybrid rice varieties. All of these varieties show high quality, high
and stable yield and good adaptability, reflecting the “core” role of Yuenongsimiao as a high-quality parent. Yuenongsimiao
has been widely applied to the basic theoretical researches of cultivation, physiology and so on. Yuenongsimiao has become the
leading variety of high-quality rice in Guangzhou since 2012, and is selected as the leading variety of agriculture in Guangdong
Province for nine consecutive years from 2013 to 2021, which has extremely important production value in South China and the
Middle and Lower Reaches of the Yangtze River. |
