Proceedings of the 3rd International TRIGO Wheat Yield Potential p. 27-33Summary: A total of 905 accessions including synthetics, durums, landraces, elite lines, and gene bank accessions formed into different panels-high biomass association mapping panel (HiBAP), bread wheat diversity (BWDiv) panel, synthetic panel (SynPan), and durum wheat panel-were screened using single nucleotide polymorphism (SNP) markers. These populations were grown at the IWYP-HUB in Cd. Obregon, NW Mexico, for physiological and agronomic characterization. Except for the durum panel, which was genotyped using the DArTseq™ genotyping method, all other populations were genotyped by 35K SNP array. The genetic diversity and population structure of each population were analyzed individually which indicated genetic diversity and subgroups within the population. The HiBAP and BWDiv panels were divided into subgroups based on the genome of Weebil 1, a line highly used in the pre-breeding program at CIMMYT. The synthetic panel was sub-grouped into three groups but the grouping was not based on geographical origin of the Ae. squarrosa accessions nor on the most frequent durum parent. The durum panel was grouped into five subpopulations based on the pedigree of the lines.
