Accomplishments

Despite restrictions due to the pandemic, the group continued to conduct research, extension programs and other outreach related to potato viruses and virus-like organisms. For example:

An SCRI grant, led by Dr. Alex Karasev at the University of Idaho, was awarded in fall of 2021. The work proposed involves numerous collaborators across multiple states who will continue efforts to develop management solutions for necrotic viruses that infect potato.
Advances in dormant tuber testing for PVY (potato virus Y) continue. However, the industry is not yet at the point of replacing seed-lot grow outs, particularly since dormant tuber testing cannot detect chemical injury.
Optimal sampling of dormant tubers was identified and proposed, to reduce false negatives to an acceptable level. Refining tuber testing for PVY is ongoing, as in previous years. Studies to determine optimal sampling time after harvest continue.
Annual seed lot trials were conducted in at least two sites, which aids growers in measuring overall seed quality. Dr. Kenneth Frost (Oregon State University) and Dr. Mark Pavek (Washington State University) conduct such trials each year.
The Oregon State University entomology program led by Dr. Silvia Rondon has been focusing on phytoplasmas for several years, particularly on the potential movement of phytoplasmas from potatoes to carrots and vice-versa.

Molecular interactions between potato and PVY are being studied by the Plant Biology Program at Oregon State University, led by Dr. Aymeric Goyer, to better understand the resistance mechanisms and genes involved.

Impacts

Topic-oriented breakout sessions allowed members to discuss and identify goals and objectives related to specific topics. Opportunities for multi-plex testing, developing assays for powdery scab were discussed during the Diagnostics and Pathogen Detection breakout session. Attendees of the Breeding session discussed the value the developing PVY-resistant material, challenges of vector-borne viruses (soilborne vs. aphid-borne); and identified phenotyping as the major bottle neck in identifying QTL/markers linked to resistance. During the Vector-Pathogen Relations session, attendees identified a need to better understand the interaction between the powdery scab pathogen and the microbiome, especially with respect to suppressive soils; action thresholds for insects and pathogens need to be updated; and a better understanding of the biology of soilborne pathogens and attraction of vectors to host and non-host plants. Defense mechanisms and tools to visualize presence of pathogens in plants were discussed during the Host-Virus Interaction session. The discussion during the Post-Harvest Test breakout session focused on the importance of winter grow out tests and the need to identify a good field site for the future.
State certification agency personnel from Oregon, Idaho, Montana, Wisconsin, Colorado, Nebraska, North Dakota, Maine, and New Brunswick (Canada) provided seed certification reports, indicating number of acres planted and accepted for certification. Some areas noted a decrease in PVY incidence, while others observed an increase. Overall, acres were about on par with previous years in most locations, with reduced acres in areas that experienced drought or excessive rain fall. Several areas reported seed lots being taken out of certification due to chemical damage.
Presentations on current research were provided by attendees. Over-arching categories for updates included virus-like organisms, diagnostics, TRV/PMTV, PVY biology, PVY management, and other topics. These updates generated good discussion and showed progress in areas such as dormant tuber testing, sampling strategies, PVY management with mineral oils and biologicals, tools to breed for resistance, variety reactions to PMTV, and others.
