传统上，观赏植物育种的重点是提高植物的新奇、产量、质量和对生物或非生物胁迫的抗性。然而，实现这些目标往往需要艰苦的杂交育种，而精确的育种技术一直没有得到充分利用。幸运的是，植物基因组测序和编辑技术的最新进展为革命性的观赏育种开辟了令人兴奋的新领域。在这篇综述中，我们概述了观赏转基因育种的现状，并提出了四种有前途的育种策略，这些策略在作物育种中已经证明是成功的，并且可以在基因组编辑的帮助下适用于观赏育种。这些策略包括重组操作、单倍体诱导物产生、克隆种子生产和反向育种。详细讨论了每种策略的研究进展、应用现状和可行性。
Ornamental breeding has traditionally focused on improving novelty, yield, quality, and resistance to biotic or abiotic stress. However, achieving these goals has often required laborious crossbreeding, while precise breeding techniques have been underutilized. Fortunately, recent advancements in plant genome sequencing and editing technology have opened up exciting new frontiers for revolutionizing ornamental breeding. In this review, we provide an overview of the current state of ornamental transgenic breeding and propose four promising breeding strategies that have already proven successful in crop breeding and could be adapted for ornamental breeding with the help of genome editing. These strategies include recombination manipulation, haploid inducer creation, clonal seed production, and reverse breeding. We also discuss in detail the research progress, application status, and feasibility of each of these tactics.
