Webinar to explore programs converting cultivars to diploids

An upcoming webinar will provide updates on breeding programs working to convert cultivars to diploid varieties.

The Potato Association of America (PAA) Breeding & Genetics Section technical webinar will feature two prominent researchers: David Douches of Michigan State University and Han Tan of the University of Maine.

The April 1 session will explore bow breeding programs nationwide are converting conventional potato cultivars to diploids, which will increase access to desirable genetics, as well as practical strategies for integrating diploids into breeding programs. The webinar will also delve into advanced breeding strategies and clones being developed as part of this effort.

Registration is free for PAA members and $49 for nonmembers.

Douches has more than 40 years of experience in potato breeding, genetics and biotechnology.

His breeding program directed toward the development of improved cultivars in Michigan focuses on integrating genetic engineering/gene editing to improve Colorado potato beetle resistance, along with resistance to scab, late blight, PVY, blackspot bruising and chip processing from long-term storage.

Tan leads the University of Maine’s diploid potato breeding program. He works closely with the university’s conventional potato variety development and enhancement program as well as the USDA ARS Eastern potato breeding program to improve potato haploid induction and inbreeding for diploid potatoes.

The programs are also working to develop disease-resistant varieties by utilizing available genetics and genomics technology.
