2019 SPHI Brief 34. Genomic tools for sweetpotato improvement project (GT4SP).

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
