“…In the breeding programmes under consideration, the use of DNA markers has been confined to quality control (recognition of the real genotypic identity of trees - Archambeau et al 2023). Several pilot studies are underway, however, to use DNA markers to enhance selection within a marker assisted selection or genomic selec-tion scheme for some of the species considered here.…”

“…In particular, as a result of the B4EST initiative, a commercial multi-species 4TREE array was designed with 50K SNPs for Populus sp., Fraxinus sp., Pinus pinaster, and Pinus pinea (Archambeau et al 2023, Guilbaud et al 2020. Two other arrays were also generated within the same project: one for Scots pine (Kastally et al 2021) and one for Norway spruce (Bernhardsson et al 2020).…”

“…An important issue in long-term tree breeding is the need to maintain high levels of genetic variability for future breeding while maximising the short-term response to selection (Archambeau et al 2023). Such levels of genetic variability over the long term may prove essential in the current context of substantial environmental change to ensure a minimum evolutionary potential in the face of unplanned pressures other than those generated by genetic gain.…”

Genetically improved forest reproductive materials are now widely accessible in many European countries due to decades of continuous breeding efforts. Tree breeding does not only contribute to higher-value end products but allows an increase in the rate of carbon capture and sequestration, helping to mitigate the effects of climate change. The usefulness of breeding programmes depends on (i) the relevance of the set of selected traits and their relative weights (growth, drought tolerance, phenology, etc.); (ii) the explicit management of targeted and "neutral" diversity; (iii) the genetic gain achieved; and (iv) the efficiency of transferring diversity and gain to the plantation. Several biological factors limit both operational breeding and mass reproduction. To fully realise the potential of tree breeding, the introduction of new technologies and concepts is pivotal for overcoming these constraints. We reviewed several European breeding programmes, examining their current status and factors that are likely to influence tree breeding in the coming decades. The synthesis was based on case studies developed for the European Union-funded B4EST project, which focused on eight economically important tree species with breeding histories and intensities ranging from low-input breeding (stone pine, Douglas-fir and ash) to more complex programmes (eucalyptus, maritime pine, Norway spruce, poplar, and Scots pine). Tree breeding for these species is managed in a variety of ways due to differences in species' biology, breeding objectives, and economic value. Most programmes are managed by governmental institutes with full or partial public support because of the relatively late return on investment. Eucalyptus is the only tree species whose breeding is entirely sponsored and managed by a private company. Several new technologies have emerged for both phenotyping and genotyping. They have the potential to speed up breeding processes and make genetic evaluations more accurate, thereby reducing costs and increasing genetic gains per unit of time. In addition, genotyping has allowed the explicit control of genetic diversity in selected populations with great precision. The continuing advances in tree genomics are expected to revolutionise tree breeding by moving it towards genomic-based selection, a perspective that requires new types of skills that are not always available in the institutions hosting the programmes. We therefore recognise the importance of promoting coordination and collaboration between the many groups involved in breeding. Climate change is expected to bring in new pests and diseases and increase the frequency of extreme weather events such as late frosts and prolonged droughts. Such stresses will

Specialized botanical gardens such as a rose garden, or rosarium, play a significant role due to their multifunctional nature surpassing simple gene bank assembly. Thus, this study conducted a detailed analysis of a rose garden through field and desk research, SWOT analysis, and ecosystem services assessment, aiming to determine the major strengths and opportunities, as well as weaknesses and threats that can promote or constrain the establishment of the first national rosarium in Serbia. After the analysis, the need for complete green area reconstruction arose to achieve both attractiveness and usefulness. Featuring old varieties, wild species, and companies’ own specific rose collections, the proposed garden has the potential to contribute major ecosystem services reflected in environmental, societal, and economic purposes. Owing to the uniqueness of the breeding program and collections created in the past decade, specific thematic parts—open field or greenhouse classroom, ‘roses under the glass bell’, abundant river flow, pollinators’ shelter, taste garden, and scent garden—are envisaged in the future exemplary rosarium that would not be only a classroom but a showroom for interested nurseries, small-scale functional food producers, flower shops, or amateur gardeners that would become aware of new cultivars and expand their marketing and utilization.
