Breeding new and high performing cultivars with market‐preferred traits take more than 10 years in the absence of an integrated pre‐breeding programme. During the early phases of breeding a significant amount of time, space and resources are invested in the selection and genetic advancement stages after initial crosses are performed with parental genotypes. Speed breeding has the potential to reduce the time required for cultivar development, release and commercialization. The objective of this review was to present the key opportunities and challenges of speed breeding to guide pre‐breeding and breeding programmes. Key challenges of speed breeding include: (a) access to suitable facilities, (c) staff trained in the protocol, (b) adopting major changes to breeding programme design and operations, and (d) the need for long‐term funding. The current review highlights the potential advantages of speed breeding for the successful development and release of pure line cultivars in self‐pollinated crops in ~5 years versus 8 to 10 years when using traditional methods.

速育的机遇与挑战：综述

在没有综合的预育计划的情况下，要培育出具有市场偏爱的性状的高性能新品种，需要十多年的时间。在育种的早期阶段，在与亲本基因型进行初次杂交后，大量的时间，空间和资源被投入到选择和遗传改良阶段。快速育种有可能减少品种开发，发布和商业化所需的时间。这次审查的目的是介绍快速育种的主要机遇和挑战，以指导预育和育种计划。快速育种的主要挑战包括：（a）获得合适的设施，（c）受规程培训的工作人员，（b）对育种计划的设计和操作进行重大改变，以及（d）需要长期资金。
