The CABANA workshop Genomic Analysis of Crop Biodiversity using R, took place 25-28 June 2019, at LANGEBIO, CINVESTAV in Mexico. Eighteen delegates from five countries were trained in molecular markers, R programming, hierarchical clustering, various diversity metrics from DNA markers, core subset selection, association phenotype-genome and design of biodiversity studies. As requested by the trainees, concepts and analysis on GWAS (Genome-Wide Association Studies) were also covered. Data for the hands-on activities came from maize microsatellites, chilli pepper transcriptome and a large data set of wheat SNPs. CABANA provided fellowships to nine delegates from Latin America. Our thanks go to instructors Octavio Martínez and and Jose Manuel Villalobos-Escobedo (Langebio, Cinvestav, Mexico) and M. Humberto Reyes-Valdés (Universidad Autónoma Agraria Antonio Narro, Mexico).
