| 中文摘要: |
| 广 8A 是以含广东野生稻亲缘的优质早籼稻增城丝苗-8 选为母本，与保持系 1325B 杂交制保后再与 325A 测交并回交转育而成的野败型优质高产丝苗型籼稻不育系。该不育系由广东省农业科学院水稻研究所选育而成，具备稻米品质优、配合力强、抗病性好、综合农艺性状优良的特点。自 2010 年通过广东省技术鉴定以来，以其为亲本配组并通过国家、省级审定或授权的水稻新品种已达 44 个，审定区域包括广东、广西、福建、云南、湖南、湖北和四川等省（区），这些品种均表现出优质、高产稳产、适应性强的特点，充分体现了广 8A 作为水稻“广东芯”的作用，并作为试验材料广泛应用于栽培、生理等基础理论研究。其中，以广 8A 配组选育的广 8优 165、广 8 优金占、广 8 优 2168 组合，在省级区试中均呈现丰、抗、优高度协调性，并连续 4 年被遴选为广东省农业主导品种，从 2017 年至今，在广东累计推广面积达到 26 万 hm2 以上，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: |
| Guang 8A is a wild abortion Simiao type male sterile line of indica rice with high quality and high yield, which was developed by crossing the female parent Zengcheng Simiao-8 (a high-quality indica rice possessing relationship with Guangdong wild rice) with the maintainer line 1325B, and then backcrossing with 325A after test-crossing. It was selected by the Rice Research Institute of Guangdong Academy of Agricultural Sciences, with the characteristics of good quality, strong combining ability, disease resistance and excellent comprehensive agronomic characters. Since it passed the
technical identification of Guangdong Province in 2010, 44 new rice varieties have been approved or authorized by the state and provincial governments in China, including Guangdong, Guangxi, Fujian, Yunnan and Sichuan Province (Region). All of these varieties showed the characteristics of high quality, high and stable yield and strong adaptability, fully demonstrating the role of Guang 8A as the "Core Rice of Guangdong". In addition, it was selected as test material and widely applied in the basic theory researches of cultivation and physiology. Among them, Guang 8 you 165, Guang 8 you Jinzhan and Guang 8 you 2168 showed high coordination of abundance, resistance and quality in provincial regional tests and have been selected as the leading agricultural varieties in Guangdong Province for four consecutive years. From 2017 to date, the accumulative promotion area in Guangdong has reached more than 0.26 million hm2, which has extremely important production value in South China and the middle and lower reaches of the Yangtze River. |
