Abstract

Woody ornamental plants comprise a large number of genera, species, and cultivars that display a huge amount of phenotypic diversity. New introductions mainly result from natural existing variation or from selections in open-pollinated populations. Systematic commercial breeding mainly takes place in a few important genera. More advanced techniques such as interspecific hybridization and polyploidization have been successfully adopted to broaden the possibilities of woody plant improvement. Because of increased sophistication in marketing and branding, visual attractiveness at the point of sale has become one of the major breeding goals. But the real challenges continue to be biotic (disease and pest) and abiotic stress resistance (winter hardiness, heat, drought, pH, and flooding tolerance). In addition, some new trends are observed, such as breeding for sterility, breeding for multipurpose, and breeding and selecting of native plants with an ecological function. This review also provides an overview of the current status of genomics and genetic engineering in woody plants and the potential of application of genome-editing technologies to enable faster and more precise breeding.
