[EN] Adapting eggplant (Solanum melongena) cultivars to climate change requires the development of drought tolerant cultivars. In order to identify sources of variation for drought tolerance we have characterized nine accessions of eggplant and six of related species for tolerance to drought using a control with optimum irrigation and a drought treatment with a 50% reduction of irrigation. Many differences were found in the materials studied for the four parameters measured (leaf length and width, plant height and dry biomass). The materials with better performance have been S. elaeagnifolium and one accession of eggplant, while the most discriminant traits have been plant height and dry biomass. Overall, the results indicate that there is a large diversity in the germplasm of eggplant and related species for tolerance to drought. ; This work was completed as part of the initiative "Adapting Agriculture to Climate Change: Collecting, Protecting and Preparing Crop Wild Relatives", which is supported by the Government of Norway. The project is managed by the Global Crop Diversity Trust with the Millennium Seed Bank of the Royal Botanic Gardens, Kew and is implemented in partnership with national and international gene banks and plant breeding institutes. ; Fita Fernández, AM.; Fioruci, F.; Plazas Ávila, MDLO.; Rodríguez Burruezo, A.; Prohens Tomás, J.

1 19 213 7 ; S ; [EN] The need to boost agricultural production in the coming decades in a climate change scenario requires new approaches for the development of new crop varieties that are more resilient and more efficient in the use of resources. Crop wild relatives (CWRs) are a source of variation for many traits of interest in breeding, in particular tolerance to abiotic and biotic stresses. However, their potential in plant breeding has largely remained unexploited. CWRs can make an effective contribution to broadening the genetic base of crops and to introgressing traits of interest, but their direct use by breeders in breeding programs is usually not feasible due to the presence of undesirable traits in CWRs (linkage drag) and frequent breeding barriers with the crop. Here we call for a new approach, which we tentatively call 'introgressiomics', which consists of mass scale development of plant materials and populations with introgressions from CWRs into the genetic background of crops. Introgressiomics is a form of pre-emptive breeding and can be focused, when looking for specific phenotypes, or un-focused, when it is aimed at creating highly diverse intro-gressed populations. Exploring germplasm collections and identifying adequate species and accessions from different genepools encompassing a high diversity, using different strategies like the creation of germplasm diversity sets, Focused identification of germplasm strategy (FIGS) or gap analysis, is a first step in introgressiomics. Interspecific hybridization and backcrossing is often a major barrier for introgressiomics, but a number of techniques can be used to potentially overcome these and produce introgression populations. The generation of chromosome substitution lines (CSLs), introgression lines (ILs), or multiparent advanced inter-cross (MAGIC) populations by means of marker-assisted selection allows not only the genetic analysis of traits present in CWRs, but also developing genetically characterized elite materials that can be easily ...
