Abstract
Crop breeding changed substantially with the deployment of genomics technology over the last decade and DNA markers are now the norm in many plant breeding efforts.
Genomics strategies provide increased genetic gains, higher efficiency of trait selection, stacking or gene pyramiding for important traits, and shortened breeding cycles for new cultivar development.
USDA Agricultural Research Service (ARS) established Breeding Insight (BI) in 2018 as a public-private partnership with Cornell University to accelerate the development of tools supporting genomics-enabled plant breeding and transfer technology and expertise to ARS breeding efforts in specialty crops and animals that otherwise would not have the resources or community of practice to implement genomics strategies.
Breeding Insight currently supports ARS breeders working on 25 diverse plant and animal species and will soon provide services for the entire portfolio of more than 65 species.
Woody landscape plant breeding was recently added to the BI portfolio, and an overview of the status and future prospects of genomics-enabled breeding in ornamental plants will be presented.
Challenges, opportunities, and needs (including understanding traits and genomes, genetic architecture, and efficient DNA marker pipelines) will be included.
ARS’s perspective on the future of genomics-enabled breeding in the context of international scientific collaboration includes all stages of new cultivar development from characterization of germplasm in gene banks, to pre-breeding, parent and seedling selections, and evaluation of elite materials for plant release.
The genomics-enabled revolution in plant breeding in ARS will contribute to new, high-quality woody landscape cultivars and their adaptation to new climatic and consumer scenarios.
The community of practice supporting genomics-enabled breeding in woody landscape plants will support international connections in the collaborative scientific network for ornamental plants and training the next generation of woody landscape plant breeders.
