Implementation of genomic selection in public-sector plant breeding programs: Current status and opportunities

Abstract: The usefulness of genomic selection (GS) for improvement of complex traits has been demonstrated in plant and animal breeding. While fully adopted in the livestock sector and commercial plant breeding, the implementation of GS in public-sector plant breeding programs lags. The goal of this review is to discuss advancements in GS implementation and opportunities for near-term and long-term adoption in public-sector plant breeding programs. We also highlighted specific applications of GS for cultivar development ordered by what we believe to be their feasibility, where feasibility is defined by cost, disruption to current breeding practices, and risk.

摘要：基因组选择（genomic selection, GS）用于改良复杂性状的应用价值已在动植物育种领域得到证实。尽管该技术已在畜牧行业与商业化植物育种中全面落地，但在公共部门植物育种项目中的推广仍相对滞后。本综述旨在探讨基因组选择的实施进展，以及公共部门植物育种项目实现其近期与长期应用的潜在机遇。本文还按照我们认定的可行性顺序，重点梳理了基因组选择在品种培育中的具体应用场景，其中可行性由成本、对现行育种实践的干扰程度及风险三方面共同界定。
