We developed genomic and genetic resources for sweetpotato improvement, including genome sequencing and annotation of two diploid relatives, to be used as reference genomes for cultivated sweetpotato. We developed a sequence-based single nucleotide polymorphism (SNP) genotyping platform, with supporting bioinformatics and analytical tools to facilitate marker-assisted breeding. We additionally developed a database for data storage, analysis and sharing. We carried out multi-location phenotyping of populations and marker-trait association, quantitative trait loci (QTL), and causal gene validation studies, as well as genomic selection trials. We enhanced capacity for genomic-assisted breeding in African sweetpotato research programs through workshops, webinars, short and long-term training opportunities
