[EN] Commercial varieties of eggplant, Solanummelongena, are vulnerable to future challenges related to the effects of climate change. It is therefore important to provide plant breeders and farmers with plant material that can meet these new challenges by exploiting some of the natural abilities of wild relatives.The aim of this study was to appreciate the transmissibility of interesting traits to the descendants by evaluating the agro-morphologic diversity of 8 accessions of S. melongena, 8 accessions of 6 wild or cultivated relatives and 36 interspecific progenies. Mean values of agro-morphologic traits revealed heterosis effects for vegetative growth characteristics in interspecific hybrids between S. melongena and wild relatives. A Principle Component Analysis identified three morpho-groups that discriminate S. insanum, S. anguivi and S. dasyphyllum, the respective wild ancestors of the three main cultivated eggplant species, S. melongena, S. aethiopicum and S. macrocarpon. In addition, interspecific hybrids belong to the same morpho-groups as the wild parental accessions, which could therefore carry dominant alleles of genes controlling the expression of these agro-morphologic traits. In general, fertile interspecific hybrids have values of production characteristics intermediate between those of parental accessions, suggesting the involvement of genes with additive effects in the expression of these traits. ; This work was undertaken 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 implemented in partnership with national and international gene banks and plant breeding institutes around the world.
