Brief Summary of Minutes of Annual Meeting

On October 23, participants boarded a bus to tour and learn about Pacific Northwest blueberry and red raspberry production. Stops included: 1) Bow Hill Blueberry to learn about organic blueberry production and value addition on a small farm, 2) Oxbo International to learn about and observe manufacturing of fruit harvesting equipment, 3) Northwest Plants to learn about commercial tissue culture propagation of small fruit species, and 4) Enfield Farms to see raspberry and blueberry production, processing, and packaging.

On October 24, DeVetter and Moore greeted members at the Washington State University Northwestern Washington Research and Extension Center (WSU NWREC). DeVetter and Mr. Chad Kruger, director WSU NWREC, welcomed the group and gave an overview of agriculture, small fruit production, and extension/outreach in northwest Washington. Following this, attendees introduced themselves and reports were distributed.

Reports were given by state, institutional, or company representatives from October 24-25. Research, industry, and extension activities were addressed for Oregon, Virginia, North Carolina, Ontario, Michigan, New York, Minnesota, Pennsylvania, USDA (Corvallis, OR), Arkansas, North Dakota, Nova Scotia, British Columbia, Utah, and Washington State. Driscoll’s, Naturipe, and Pacific Berry Breeding also gave oral reports. A tour of WSU NWREC was given after lunch on October 24 and Moore and DeVetter also coordinated a tasting of WSU and USDA-ORS raspberry selections that same day. The business meeting was also held on October 24 to accommodate people that were leaving on Oct. 25. Oct. 25 was dedicated to finishing reports. 

Business Meeting Minutes:

Lisa DeVetter from Washington State University called the meeting to order at 2:15 (Pacific Time). Mary Rogers from University of Minnesota transcribed notes and served as secretary. University of Minnesota will be the host institution for the 2019 meeting.

Old Business

• The 2017 minutes were reviewed. The following edits should be made: check spelling for ‘Demchak’, change from ‘Karen Lewers’ to ‘Kim Lewers’, change the title from ‘Pennsylvania, PN to PA’. Motion to approve 2017 minutes with these edits: Chad Finn, seconded: Pat Moore.
• Project renewal was re-visited. Vance emphasized that the renewal is not too onerous, but it does take some time to compile and should begin in 2019. It is best to have a team of 2-3 people work on this together. The renewal should focus on the value of the meeting for collaboration, and perhaps less focus on research updates. Harlene Hatterman-Valenti from North Dakota State University volunteered to serve on the renewal committee. Lisa DeVetter from Washington State will also help.
• Participation was discussed, as it is essential for the function of NCCC-212 and attendance is tracked and important for the renewal process.
  • Video conference at the meetings was discussed. The point was made that this technology can improve accessibility of the meeting to those who cannot travel and attend in person. Perhaps we should formalize this and make it a requirement for hosting? It was decided that success is mostly dependent on the capabilities of the location and sometimes there are technical issues. For this reason, the decision to provide video conferencing should be left to the meeting host and organizer.
  • The question was posed on how participation can be increased and whether it makes sense for extension professionals (i.e. county extension agents and educators) to attend. Chad Kruger, director of NWREC weighed in that sitting in on the meeting was helpful to him personally, as he typically does not have access to the information presented here. Therefore this audience might make sense and it was determined that invites can be left to the host institutions.
  • Industry participation was discussed. It was mentioned that the representatives from industry provide a valuable perspective and contribute to the discussion by providing reports. Phil Stewart (Driscoll’s) affirmed that this meeting is valuable for him and colleagues. Ellen Thompson (Pacific Berry Breeding) pointed out that participation comes down to getting industry reps to add their colleagues to the email list if we want to increase participation from this sector.
  • Grower participation was discussed, but it was decided that growers are generally too busy and this may be a “big ask” for them, and they might only find a small portion of the meeting valuable.
  • Participation from international partners was discussed—should we do more to reach out to colleagues in Mexico and Canada? Attendance is open and not regulated “top down”, therefore any one could attend, however land grant representatives have access to funding to attend these meetings which makes it easier to attend. There is potential for more collaboration between NASGA and NARBA and the Mexico Aneberries consortium.
• Reporting and use of meeting time
  • Vance again emphasized that future reporting should focus more on collegial interactions and collaborations, while the content of the research reports could be reduced. Other ideas to foster more collaboration were discussed:
    • Coordinated US/Canada cultivar trials?
    • More time for informal conversations
    • Special session on enhancing and fostering collaboration, build time in the schedule for attendees to discuss mutual interests
    • Special discussion times blocked out rather than so much time on reports
    • Reduce reports to 5 minutes with bullet “take home” points highlighted
    • Discussion questions could be solicited prior to the next meeting (i.e. what are the next steps we could take to make the strawberry industry more sustainable?)
    • Perhaps the state reports could be pre-reading and the meeting time could be devoted to more discussion
    • We could organize the reports by commodity rather than by state
    • Maybe a joint publication as the result of this meeting?
  • Reporting guidelines—Kim Hummer noted that the format and reporting guidelines depends on how the project was written and this can be something to consider as we are approaching renewal. By consensus, it was determined that we should keep reporting by state and not commodity, even though discussion happens around the crops.

New Business

• Lisa DeVetter: The midterm report is due December 15^th. There are four categories: progress report, accomplishments since the committee was last approved, coordination and linkages, and evidence of collaboration. We need to have evidence of interaction to justify the value in bringing people together.
• Discussed next meeting locations in 2019 and 2020. Mary Rogers will host the next meeting at the University of Minnesota in 2019. Gina Fernandez will host in 2020 at North Carolina State. Phil Stewart mentioned Driscoll’s could be an option for hosting in 2021. Beatrice Amyotte will consider hosting in Nova Scotia in 2022.

Harlene Hatterman-Valenti made the motion to adjourn; seconded by Kim Hummer. Meeting ended at 3:02 pm Pacific Time.

Short-term Outcomes:  Most participants have extension appointments and/or regularly communicate with growers and other members of the small fruit industry. Regular communication provided by NCCC-212 annual meetings allows for everyone to share information, increase knowledge, and extend that knowledge to regional industries. This extension of information occurs through publications of extension articles and/or newsletters, presentations at workshops and local and regional meetings (e.g. Great Lakes Expo, Mid-Atlantic Fruit and Vegetable Convention, Washington Small Fruit Conference, South East Regional Fruit and Vegetable Conference, Lower Mainland Horticulture Improvement Association Grower Short Course), webinars, web sites, and one-on-one communications.    

Outputs:  This project has resulted in the release of numerous new cultivars and the development of germplasm and selections with specific traits needed for adaptation to regional industries. For example, collaborative breeding programs at USDA-Corvallis, Washington State University, and British Columbia have produced cultivars that meet the needs of strawberry, caneberry (i.e. red raspberry and blackberry; some black raspberry), and blueberry growers in the Pacific Northwest. Some of those traits include machine harvestability and disease tolerance or resistance. They also actively collaborate with other programs, such as the University of Arkansas and private breeding companies, which allows for advancement and gains in knowledge of cultivars and selections outside of the regions in which they were bred. Several projects related to use of protected culture (high tunnels and low tunnels, exclusion nets) are producing strong evidence that certain disease and insect problems can be greatly reduced in strawberry or raspberry production, while others can become more problematic. Mulch application is also showing benefits in small fruit production and advancements in organic berry production are being made. See also “Publications”.

Activities -  Collaborative projects: Over 50 projects fall under the umbrella of this NCCC-212 project are underway in addition to the ones listed below. Those listed below highlight many examples of multi-state (and multi-country in the case of Canada) collaborations. There are also several large, interdisciplinary project proposals that are in development and being submitted in the areas of Vacciniumspecies breeding and advancement, plasticulture, machine harvesting for fresh markets, blackberry industry needs assessments, and soilborne disease management. NCCC-212 provides opportunities for researchers across the US and Canada to formulate, plan, and advance competitive project proposals that benefit the small fruit industry.
