Short-term Outcomes:

Forty-one participants from 11 US state universities, one Canadian province, the USDA-ARS, and eight private companies participated in the NCCC-212 meeting this year.  Additionally, representatives from two other states (Wisconsin and Washington) submitted state reports even though they were unable to attend in person. The 2022 meeting was the first ‘in person’ meeting of NCCC-212 since 2019. 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. Breeding programs at USDA-Corvallis, Washington State University, and British Columbia, University of Arkansas, Rutgers, Michigan State University, University of Minnesota, University of Florida, and North Carolina State University have produced cultivars that meet the needs of strawberry, raspberry, blackberry, blueberry, grape, muscadine and other small fruit growers across North America. Many of these breeding and genetics programs have also developed new genomes (for blueberry, blackberry, billberry, etc…) and markers for traits of economic interest to accelerate cultivar development efforts.  NCCC-212 collaborators have conducted research on pruning, training, and thinning techniques, propagation methods, protected culture, integrated pest and disease management, and other topics to improve the productivity, sustainability, and profitability of production systems. Other research has focused on organic methods, pollination, variety testing, and modeling for cold hardiness and disease risk. Research has also been conducted on the effects of cultivar, environment, and cultural management factors on fruit flavor, texture, shelf life, and nutritional quality.  The results of these projects have been disseminated to stakeholders via publications, field days, grower visits, conferences, and production guides. Many of these extension efforts have been regional or national collaborations. Overall, the NCCC-212 participants coauthored at least 74 peer reviewed publications in the past year (see also “Publications”) Most of these publications resulted from multi-state collaborations.

 

Activities:

 

A comprehensive list of activities are described in individual state reports, which are available for download at https://www.uaex.uada.edu/farm-ranch/crops-commercial-horticulture/horticulture/nccc-212-22.aspx.  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. Specific examples of large multi-state (and multi-country in the case of Canada) collaborations are listed below.  The objectives of the NCCC-212 project are:

  1. Develop small fruit germplasm through cooperative breeding and evaluation programs.
  2. Develop practices for small fruit production tailored for climatic and market needs of growers.
  3. Evaluate pre- and postharvest fruit quality components, including enhanced flavor, texture/firmness, shelf life, and phytonutrients.
  4. Identify opportunities and collaborate on the development of extension resources for multistate, regional, national, and/or international audiences.

Many of these large collaborative projects address all four objectives.  Therefore, the objectives addressed are listed below each project.

Impacts

  1. An overarching goal of the project is to give small fruit growers needed tools to adapt to changing conditions and new challenges, thus improving food security as related to berry crop productivity and promoting farmer profitability and sustainability. Through coordinated efforts that this project encourages, as well as by providing opportunities for increased communication and contributions of knowledge, project participants continue to work towards developing and testing new germplasm and cultivars that can be grown under a range of conditions, as well as developing new cultural production techniques that provide growers additional control over growing conditions, pests, and diseases. Examples of impacts from participants in various states and presented on during this reporting period are provided below. A more comprehensive list of impacts can be found in individual state reports.
  2. Objective 1 - Develop improved small fruit germplasm through cooperative breeding and evaluation programs. The Arkansas Clean Plant Center has recently expanded and functions as a full/vertical National Clean Plant Network Center performing cleanup, diagnostics and maintenance. The lab will be cleaning at least 15 accessions from public breeding programs and will be introducing cryotherapy (in addition to chemo and thermotherapy) to the technologies used for virus eliminations. Pre-G1 testing will be following the Villamor et al. (Plant Disease, 2022) protocol for high throughput sequencing. The clean-up service is offered for a fee to private industry and any public material that exceeds the 15 accessions quota. A 550 ft2 closed-system foundation greenhouse has been approved and construction has started. In addition to Illumina the Center has introduced the Oxford Nanopore MinION HTS platform in the services it provides. The Arkansas Center will offer full testing services to the industry at-large starting in 2023.
  3. Objective 2 - Develop practices for small fruit production tailored for climatic and market needs of growers. A research team at Oregon State University and USDA-ARS is involved in a four-year research project (2020-2023) investigating vineyard nutrient management funded by NIFA-SCRI and led by Washington State University. As a part of this project, they conducted research on cluster thinning impact on fruit and wine quality. Through active engagement in this research, vineyard managers and winemakers have learned how to implement research on their site and how to utilize data collection protocols. Many of them report having a greater understanding of the whole vineyard system, are much more observant in the vineyard, and are beginning to look at yield management differently. Project collaborators have confidently increased yields by 0.5 ton per acre annually without compromising quality. This has led to a marked 25% increase in yields noted in the state grape statistics, which can harness an additional $1600/acre in grape sales on average for those who increase their yields. If this practice is applied across even half the 23,707 bearing Pinot noir acres in the state, this is an additional $22 million per year in farm gate value for Pinot noir grapes. Many collaborators also said that the increased yield is leading to more volume of quality wine (with no reduction in bottle price), as they have not seen a reduction in fruit or wine quality with yield increases between 0.5-1.0 tons per acre.
  4. Objective 3 - Evaluate pre- and postharvest fruit quality components, including enhanced flavor, texture/firmness, shelf life, and phytonutrients. The Arkansas Quality Wine (AQW) program was launched in fall of 2020 in partnership with the Arkansas grape and wine industry and organizations to help establish quality and sensory standards for commercial wines and increase consumer awareness of the Arkansas grape and wine industry. The AQW hosts a yearly wine competition for wine produced in Arkansas with Arkansas-grown grapes (90%) and generates consumer awareness of Arkansas wines by hosting wine quality and sensory training workshops and facilitating wine tastings of Arkansas wines for winemakers and consumers. The project also promotes expansion of grape growing and winemaking in Arkansas by creating facts sheets to improve quality of Arkansas wine and use marketing and promotional items (banners, seals, and shelf-talkers) to feature AQW wines. In 2021, eight wineries submitted 52 wines for the competition, with 32 wines receiving medals and 15 wines earning AQW status. In a wine consumer study, 77 consumers evaluated 7 of the AQW wines. The online survey on Wine Purchasing and Consumption Habits of Consumers of Commercial Arkansas Wines was implemented February to April 2021 with 273 consumers completing the survey. Wine quality workshops were done to demonstrate best practices to achieve high quality wine production for beginner and expert winemakers. The project team hosted 3 virtual Crush It Arkansas! wine workshops (total of 49 attendees) in 2021 and held 3 AQW wine tasting events that showcased AQW wines to generate awareness of Arkansas wineries, the grapes used for production, and the wines (total of 173 attendees). The project is important because of the history of the grape and wine industry, the economic impact, and the potential for Arkansas as a notable U.S. grape and wine production region.
  5. Objective 4 – Identify opportunities and collaborate on the development of extension resources for multistate, regional, national, and/or international audiences. The University of Wisconsin Madison and University of Minnesota Extension program delivered a series of webinars (7) for small fruit producers and cold climate grape growers in 2022. Over 1,000 attendees for the live webinars, of which 85% reported in a post webinar survey would change production practices based on information learned through the webinars. Webinars were recorded and are archived in the Wisconsin Fruit YouTube channel (https://www.youtube.com/c/WisconsinFruit/videos)
