New Varieties from the Tri State Breeding Program

All potato breeding selections, referred to as clones, go through a strenuous evaluation process before they are released as varieties. This process can take as many as 15 years and involves hundreds of tests. Tens of thousands of inferior selections are eliminated in the process, leaving only the best clones. Advanced clones have a high probability of being released as new varieties. These clones are evaluated by growers and users and require industry acceptance as part of the process prior to release. The Tri-State breeding program works closely with the industry and growers to evaluate all aspects of each advanced clone using a system of Material Transfer Agreements, referred to as MTAs. These allow for growers to get advanced lines, test them under field circumstances and allow for enough quantity to be built up so evaluations of processing traits can be considered under actual plant conditions. This stage of grower evaluation is conducted over several years while the advanced clone is still part of the Western Regional Trials.

PVMI, the Potato Variety Management Institute, is a non-profit, grower controlled company responsible for promoting and administering the new potato varieties out of the Tri-State Breeding Program (Idaho, Oregon and Washington). In order to grow any of the newly released (or existing) PVMI varieties (see table at the end of the article), a sub-license needs to be in place. In order to grow any of the advanced clones for field evaluation an MTA must be in place. If you are not a current PVMI licensee a participation fee (equivalent to the annual license) is required in addition to the MTA. License fees are dependent on the location of the seed grower. For more information please see Getting Started, or call PVMI at (541) 318-1485.

Classic Russet has had high fresh merit in Tri-State and Western Regional Potato Variety Trials. Classic Russet is an early-maturing, russeted clone that produces a high percentage of U.S. No. 1 tubers. Its attractive tubers make it very suitable for use by the fresh-pack industry and could also be used as an early processor.

Classic Russet is resistant to external and internal tuber defects and is resistant to common scab. Classic Russet also has moderate resistance to Verticillium wilt and dry rot. Weakness include lower specific gravity and some shatter bruise was noted.

Clearwater Russet promo download (PDF)

Clearwater Russet known as AOA95154- 1 prior to release, is medium-late maturing, with oblong-long tubers that have medium-russet skin. Tubers exhibit excellent fry color out of storage and their attractiveness make this variety suitable for both processing and fresh market usage.

Clearwater Russet has high specific gravity and is resistant to sugar ends as well as most internal and external tuber defects. Clearwater Russet also is notable for having a higher protein content than those of standard potato varieties, with 38% greater concentration than Russet Burbank.  Has moderate resistance to Verticillium.
