| 英文摘要: |
| ‘Daqinyou 888’ is a new double-low, disease-resistant, and lodging-resistant hybrid rapeseed variety of Brassica napus bred by Hanzhong Agricultural Technology Extension and Training Center. It was transferred to Hanzhong Ruifeng Biotechnology Co., Ltd. in 2022. This variety was developed using the CMS male-sterile line ‘Han 11A’, which has disease resistance, lodging resistance, high oil content, and excellent combining ability, and the restorer line ‘4R’. It was registered as a non-major crop variety in 2022, with the registration number GPD Rapeseed (2022) 610111. During 2018-2020, it participated for two consecutive years in winter rapeseed variety trials at multiple sites in the upper, middle, and lower reaches of the Yangtze River. The average yields were 3 130.05 kg/hm2, 3 002.7 kg/hm2, and 2 896.2 kg/hm2, respectively, representing increases of 6.4%, 7.63%, and 7.24% compared with the control. It is a high-yielding, stable-yielding, widely adaptable, and high-quality new rapeseed variety. This paper briefly describes the breeding, yield performance in different planting areas, and demonstration and promotion of ‘Daqinyou 888’, in order to provide a reference for the large-scale promotion of this variety. |
