Recent innovations in breeding technologies have reduced the timeframe to develop improved plant varieties compared to conventional breeding processes. Technologies like speed breeding, or rapid generation advancement, may also accelerate the process of statutory variety registration. Within this procedure, improved varieties are required to satisfy distinctness, uniformity and stability (DUS) criteria to establish the unique identity of a given submission during the variety registration process. The DUS standard also provides a solid basis for seed certification, plant breeders’ rights, as well as variety maintenance throughout commercial lifespan of varieties. Currently, the overall timeline of variety registration may vary from 2 to 4 years, depending on crop type and country. In this article, we propose the concept of ‘speed DUS testing’: a rapid phenotype-based method, which could be integrated with approaches that take advantage of DNA markers. We compare methods and discuss how DUS testing could be modernized to fast-track variety registration.

植物品种注册是否与快速育种技术保持同步？

与传统育种过程相比，育种技术的最新创新缩短了开发改良植物品种的时间。快速育种或快速世代推进等技术也可能加速法定品种注册过程。在此程序中，改良品种需要满足独特性、一致性和稳定性 (DUS) 标准，以便在品种注册过程中建立给定提交的唯一身份。DUS 标准还为种子认证、植物育种者权利以及品种在整个商业生命周期内的品种维护提供了坚实的基础。目前，品种注册的总体时间表可能从 2 到 4 年不等，具体取决于作物类型和国家。在本文中，我们提出了“速度 DUS 测试”的概念：一种基于表型的快速方法，可以与利用 DNA 标记的方法相结合。我们比较了方法并讨论了如何将 DUS 测试现代化以加快品种注册。
