Towards a genome-wide association (GWA) mapping approach in globe artichoke

Here we present the first insights on a genome-wide association approach in globe artichoke, based on an association panel composed of 111 varietal types coming from the living collection maintained at AGRIS (Sardinia, Italy). The collection has been investigated through two complementary molecular approaches: (i) microsatellite (SSRs) genotyping, using 26 loci uniformly distributed throughout the genome to investigate the population structure of the core germplasm set; and (ii) genotyping by sequencing, using a two-enzymes RADseq (restriction-site associated DNA sequencing) technology, as a basis for an association mapping approach.
