Teton Russet marks newest potato variety to be used for McDonald’s World Famous Fries ®

(October 7, 2022) The Teton Russet potato variety has now been added the list used for McDonald’s World Famous Fries ®. Teton Russet is a product of a 14-year research cooperative among The U.S. Department of Agriculture, University of Idaho, Oregon State University and Washington State University potato breeding programs. With this acceptance, the Teton Russet becomes the ninth variety of potato to be used by McDonald’s in North America.

PVMI Press Release (October 17th 2022)

New Executive Director for PVMI

PVMI, the Potato Variety Management Institute is a 501(c)3, a not-for-profit organization, that was founded by the Potato Commissions of Idaho, Oregon, and Washington in 2005. Since 2006, it has been run by Jeanne Debons, the Executive Director with guidance from the nine-member PVMI Board. In July this year Jenny Durrin Gentry was appointed to replace Debons as Executive Director.

PVMI’s main mission is to promote new potato varieties that arise from the Tri-State Potato Research and Breeding Program by providing information regarding variety features and management practices to growers and thereby maximizing the success of the varieties.

Ms. Gentry has been the Director of the Seed Potato Germplasm Program at the University of Idaho for the last 6 years. Prior to that she managed a nematode laboratory at the same institution. Gentry is experienced in the industry and practiced in the art of providing services to potato growers. She has worked with the Tri-State Potato Research and Breeding Program and Pacific Northwest Potato Industry to establish and provide disease free potato germplasm.

Gentry started working with PVMI full time in October alongside Debons for the first four months. The handover period ends January 31, 2023, and at that time, Debons will retire after over 16 years at the job.

“It has been my honor to be of service to the potato industry. PVMI filled a gap that no one realized had existed prior and I am certain Jenny will do a great job of continuing that service.” Debons said.

PVMI Varieties have had their Fingerprints taken!!

Dr. Vidyasagar (Sagar) Sathuvalli, Assistant Professor Potato Breeding and Genetics with his colleagues at Hermiston Agricultural Research and Extension Center (HAREC), Oregon State University, have established the SSR Fingerprints for the PVMI varieties as well as for some other common lines. These are now available.

New Clearwater Russet Management Information

Consider physiological maturity (PM) when deciding when to harvest:

• Recognize that PM in Clearwater occurs when the crop still has ~60% green vines.

• At PM, approximately half the crop will be in late stage bulking and the other half will be under dead vines in the skin-set phase of maturation where physiological age is accelerated by temperature.

• The challenge is to minimize tuber exposure to diurnal fluctuations in soil temperature under dead vines without sacrificing the yield potential for tubers still bulking under green vines.

To maximize both yield and storage potential in ‘green vine’ harvest, plan to lift the crop within 10-18 days of PM.

For ‘vine-kill’ harvest, desiccate at ~155 DAP (~40 - 45% green vines) and harvest 7 - 14 days later.

Adhere to best management practice recommendations for minimizing bruise and other mechanical damage for bruise-free incentives and to minimize dry rot potential.

Prolonged maturation period under dead vines subjects the crop to diurnal fluctuations in temperature that accelerates tuber aging, which can affect retention of quality – dormancy length, weight loss potential, sugar buildup.

Clearwater is resistant to low temperature sweetening (LTS) and means increased tolerance of delayed harvest beyond PM for maintaining low sugars and process quality during storage. Still tubers should be harvested as close to PM as possible (e.g., within 10-18 days of PM) to maximize retention of process quality during long-term storage.

See the complete article for additional information.

The University of Idaho and Washington State University have both published new Cultural Management guides for Clearwater Russet. Go to the variety page for Clearwater to find them both.

New Website and Refurbished Research Library

Since 2012 the Washington, Idaho, and Oregon potato commissions have cooperated in research funding and management, and have called this cooperative venture the Northwest Potato Research Consortium. The Consortium has been represented on the Web by www.nwpotatoresearch.com, which included the ‘research library’ developed by the WSPC in the 2000s. Recently, a long-awaited redesign and reprogramming of the website was completed and is now live online.

For those of you with research library passwords, your old login will work on the new site. For those without a login and password, there is a user-friendly means to request a password. I encourage everyone to have a look, and of course offer feedback anytime!

Andy Jensen, Consortium Manager.
