ln the last years, whole-genome studies of vine cultivars using genotyping and sequencing technologies have added novel knowledge about the diversity, geographical relatedness, historical origin, phenotype associations, genetic markers and distribution paths of the vine. Associations between candidate genes and important agronomic traits. The further impact of genomic studies will depend on the understanding of the genotype-phenotype associations, especially for complex traits governed by polygenic architecture, genotype-environment interactions in different geographic regions. This study aims at applying Self-Organizing-Maps-portrayal to the genetics of vine, in order to visualize landscape of grape genotypes. In gastronomy, the sommelier is the wine ‘waiter’ (or ‘waitress’), who recommends combining wine with food based on traditional knowledge about the character of wine varieties, their taste and geographic origin, and thus to support the decision-making of guests for a successful dinner. In analogy, our ‘SOMmelier’-approach aims at supporting understanding genetic diversity and relatedness of grapevine genomes in the context of their geographic and historical background.
