| 得中油341是以自育细胞质雄性不育系 D1A 与恢复系 D2R配组选育的甘蓝型三系杂交油菜品种。该品种2016-2018年度参加长江上游区（陕西、四川、重庆）冬油菜多点区域试验2 a区试平均667 m2产量212.43 kg，比对照（蓉油18）增产7.85%；2017-2019年度连续两年参加长江中游区（湖北、湖南、江西）和长江下游区（安徽、江苏、浙江）油菜新品种区域试验，在长江中游区2 a平均667 m2产量203.17 kg，比华杂油12增产11.47%；在长江下游区2 a平均667 m2产量210.26 kg，比秦优10号（ck）增产8.97%。在长江流域区试中，该品种在产量、含油量、品质、熟期等方面均表现出明显优势，且适应性广，中抗菌核病、病毒病，不易倒。2019年度获得农业农村部品种登记,编号：GPD 油菜(2019)610170。本研究通过介绍该品种的选育经过、生物学特征、产量表现、配套栽培技术要点和适宜推广范围，旨在为其在长江流域推广应用提供理论依据和技术支撑。 |
| 英文摘要: |
| Dezhongyou 341 is a Brassica napus hybrid rapeseed variety bred by crossing the self-fertile cytoplasmic male sterile line D1A and restorer line D2R. The variety was evaluated in multi-location regional experiments of winter rapeseed in the upper reaches of the Yangtze River (Shaanxi, Sichuan, and Chongqing) from 2016 to 2018, average yield per 667 m2 was 212.43 kg, which was 7.85% higher than the control variety Rongyou 18. From 2017–2019, the variety participated in the regional experiment in the middle reaches of the Yangtze River (Hubei, Hunan, Jiangxi) and the lower reaches of the Yangtze River (Anhui, Jiangsu, Zhejiang) for two consecutive years. The two-year average yields per 667 m2 in the middle and lower reaches were 203.17 kg and 210.26 kg, respectively, exceeding the yields of Huazayou 12 by 11.47% and Qinyou No.10 by 8.97%. In the experiment of the Yangtze River Basin, the variety showed obvious advantages in yield, oil content, quality and ripening period.The variety demonstrates broad adaptability, moderate resistance to sclerotinia and viral diseases, and lodging resistance. In 2019, it obtained the variety registration certificate of the Ministry of Agriculture and Rural Affairs of China, registration number(Registration No.: GPD rape \[2019\]610170).This study details the breeding methodology, biological characteristics, yield performance, key agronomic practices, and suitable areas for cultivation, thereby providing theoretical justification and practical guidance for its widespread application in the Yangtze River basin. |
