Participants
Accomplishments
Breeding: Tools for phenotyping tuber color have been developed; a fingerprinting system using SNP markers is available to answer variety identify questions; molecular and hyperspectral data are being used to help predict yield.
Genome sequencing: research has been conducted to create a pan genome based upon 6 cultivars from the US and Europe; genome sequencing was used to look at relationships and diversity of the cultivated potato species.
Diploid potato breeding: self-compatibility is being genotyped in the germplasm using KASP markers for Sli; EBN1 wild species are being accessed using bridge crossing; dihaploids are being extracted by all the breeding programs to establish a diploid cultivated gene pool.
Gene editing: potatoes have been gene edited to create self-compatible lines as well as late blight resistance.
Impacts
- Variety Releases: Petoskey – chip processing storage potato with scab resistance Blackberry – purple-fleshed specialty potato for the table and chip market. Plover Russet – russet dual-purpose variety adapted to the mid-west region. Based upon certified seed acreage, previously released varieties Manistee, Mackinaw and Hodag are growing in importance in and outside the north central region
- Several collbarative competetive grants were funded; a table of these is under meeting minutes
