Petoskey is a chipper with common scab resistance, good long-term storage potential
Petoskey (MSV030-4) has excellent chip processing quality out of the field and long-term chip quality with high specific gravity and resistance to common scab, and a good size profile of uniform, round tubers.
Overview
- Parentage: Beacon Chipper x MSG227-2
- Developers: Michigan State University and the MSU AgBioResearch.
- Plant Variety Protection: To be applied for.
- Strengths: Petoskey is a chip processing potato with resistance to common scab (Streptomyces scabies). This variety has high specific gravity and yield potential, with attractive, uniformly round tubers. Petoskey has a medium vine and a midseason maturity, and has demonstrated excellent long-term storage chip processing quality. MSV030-4 has performed well in Michigan and multiple locations in the Potatoes USA National Chip Processing Trials (NCPT) and national SFA (SNaC) trials.
