Abstract:

Zheyouza 59, developed by the Zhejiang Academy of Agricultural Sciences and Zhejiang Wuwangnong Seeds Shareholding Co., Ltd. through hybridization between the male sterile line ZH3A and the restorer line HR59, exhibits multiple advantageous traits including resistance to Sclerotinia disease, pod shattering, clubroot, cold stress, and lodging, along with a suitable maturity period and clear oil quality. This variety was registered as a non-major crop cultivar in 2021 (Registration No.: GPD Rape [2021] 330252) and completed expanded regional registration in the lower reaches of the Yangtze River in 2022. It is well-suited for cultivation in winter rapeseed regions of the middle and lower Yangtze River Basin. This paper details the parental origins, breeding process, agronomic traits, and key cultivation management practices of Zheyouza 59, aiming to provide theoretical and technical support for its promotion and application, thereby enhancing Chinese oilseed supply capacity.
