摘　　要：三系杂交大葱制种技术规程(DB 1301/T 302—2018)规定了三系杂交大葱制种的产地环境、不育系和保持系的繁育、父本系的繁育、杂交种(F1)的繁育及病虫害防治等技术。该规程有助于三系杂交大葱制种程序化、简单化、标准化,降低生产成本和管理风险,提高大葱制种的产量及质量,对杂交大葱新品种的推广应用、大葱产业的进一步发展具有重要的意义。The Technical Regulation for Seed Production of Three-Line Hybrid Welsh Onion(DB1301/T 302-2018)regulates the environment of producing area,sterile-line and container-line breeding,male-parent line breeding,hybrid(F1)breeding and pest control.The regulation is conducive to programming,over-simplication and standardization of three-line hybrid onion seed production,reduce the production cost and management risk,and improve the hybrid-seed yield and quality,and is of great significance to promoting and applying new hybrid welsh onion varieties and further developing welsh union industry.
