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.

A95109-1 has had high fresh merit in Tri-State and Western Regional Potato Variety Trials. A95109-1 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.

A95109-1 is resistant to external and internal tuber defects and is resistant to common scab. A95109-1 also has moderate resistance to Verticillium wilt and dry rot. Weakness include lower specific gravity and some shatter bruise was noted.

– A new russet from the Oregon Program

AO96160-3  is a medium to late maturing selection from Oregon with medium yields and long, medium heavily russetted tubers. It has good specific gravity, excellent fry color from storage and an attractive tuber with high counts of US No.1. It is resistant to common scab and has moderate resistant to Verticillium wilt.

This clone’s main weaknesses are a medium overall yield and susceptibility to net necrosis and vascular discoloration.

AO93487-2R  has a round bright red skin, mid-early maturity for the fresh market. High US.No.1 yields, bright red skin color that does not fade in storage, shallow eye depth, few internal & external defects with high fresh market merits.

 AO93487-2R weakness include moderate skinning during harvest.

This russet selection has shown tremendous potential for long term storage, comparable to Russet Burbank, and it has resistance to scab and moderate resistance to dry rot.  It has a high early yield with large percentage of US No.1tubers.  It is both good as an early processing variety and good for early fresh pack. 

Its weaknesses include a light russet skin and susceptibility to PVY.
