Business Meeting Minutes:

Agenda for NCCC 212 Business Meeting:

Nov 2, 2021. 2-4PM EST

Chair: Mark Hoffmann

Secretary: Lisa DeVetter (volunteered)

Minutes: Taken by Lisa DeVetter and NC State Communication Team

Old Business:

• Review/amendments/approval of 2020 minutes - approved by Gina Fernandez and seconded by Lisa DeVetter
• Review of 2020 business meeting agenda – no additions; was not available

New Business:

• New reporting format: Discussion of new report Template (Vance). We had several people complaining about the reporting format, due to two reasons: a) too short; b) not inclusive (projects over several crops e.g.)
  • Vance Baird reviewed NC Regional Multi-State Project/Committee Annual Report requirements – emphasized short, succinct reports that emphasize collaborations and accessible to the general public
  • Vance Baird suggested each state representative extract most salient, top-level topics under each objective to give chair more focus to condense into a final annual report
  • Margaret Worthington suggested skipping reports and just submitting publications and a short PPT that is shared during the meeting
  • Penny Perkins-Veazie suggested a short and long report format (short report will be to aid chair in the final annual report)
  • Mark Hoffmann suggested going back to reporting by NCCC 212 objective followed by short impact statement, still list publications, possibly omit listing grants; Gina Fernandez added that each state/institutional lead can then highlight the most important projects or accomplishments per report
  • Vance Baird suggested an executive summary for each state/institutional report to aid the chair in creating a final annual report – emphasis on accomplishments, not activities
  • Nahla Victor Bassil suggested creating a Google Doc using the specific reporting format
  • NC Regional Multi-State Project/Committee Annual Report Reporting format: https://68e8efec-fd4d-4588-ad94-5d9e5e07218a.filesusr.com/ugd/4081a5_18226943c6564ef594a002c44a32266e.pdf
  • Margaret Worthington suggested not listing every presentation, just major workshops or events
  • Vance Baird added to Margaret’s statement – summarize impact of presentations (e.g., number of participants or presentations made at the international, national, rational, state, or local level)
  • Vance Baird suggested not worrying about the equipment statement
  • Brent Black stated he appreciated the long report because it helps him see what is going on elsewhere in the nation with regards to berry crop research; suggested a cover page executive summary that gives state/institutional highlights, then keeping the longer report after for those that benefit from the long report content; let the chair pull together highlights for final annual report; publications and other activities could be an appendix
  • Vance Baird mentioned publications listed can be duplicative and there should be efforts to avoid this so the chair doesn’t have to remove duplications
  • Massimo Iorizzo suggested collaborations be reflected in peer-reviewed publications and possibly grants
  • Vance Baird agreed 1-page executive summary by category or objective is a good idea and will help the chair collate information

Following Objectives were addressed through collaborative projects:

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

Short-term Outcomes:

Due to the global Covid-19 pandemic, this meeting was held entirely virtual, using the online platform Zoom. A pre-meeting survey was conducted, in which more than 70% of respondents preferred the online format, due to concerns over Covid-19. The meeting was attended by individuals from 22 institutions, similar to the 23 institutions that attended in 2020, and significantly up to the last in-person meeting with 16 institutions attending in 2019. Due to nationwide relaxing Covid-19 regulations over most of 2021, research efforts could continue and even excel. A main concern that was voiced in almost every report is the negative impact of severe weather situations (heat, rain, freeze, frost) on crop development, research and breeding programs across the country! The group voiced concern about future resiliency of fruit producing industry and discussed thoughts on research efforts to mitigate effects of climate change. Several collaborative projects are in progress in this group, and results are timely disseminated among stakeholders in research, extension and industry.

Outputs:

This project has resulted in the evaluation of germplasm and release of at least 7 new strawberry, blackberry, and bunch grape cultivars in the past 2 years and there are at least 10 institutions conducting collaborative cultivar trials. The NCCC-212 collaborations have also resulted in the development of a number of genetic resources and enhanced germplasm evaluation. For example, the USDA-ARS is working with UC Davis and MSU to develop tools and resources for strawberry breeding including a high quality reference genome. In addition we have a very wide reaching collaboration led by the USDA National Clonal Germplasm Repository (NCGR) personnel and Univ. Ark, WSU, BC Berry Cultivar Development, Cornell, University, NCSU, OSU, UC Davis, UFL, MSU, IFAPA (Spain), and others have worked together to identify important candidate genes (blackberry), fingerprinting sets based on SSR’s (raspberry, blackberry and blueberry), genetic map for insect resistance in black raspberry, conduct Rubus diversity and GWAS analysis, assist with genomic selection (blueberry). The USDA NIFA Vacinnium CAP funded project led by NCSU is working with multiple US and two foreign institutions to understand and develop resources to improve fruit quality traits and metabolite understanding of blueberries. Most of these outputs have been published in peer reviewed journals. In addition the Canadian institutions have a collaborative project within the country, called the Canadian Berry Trial Network, where they trial small fruit germplasm in BC, Nova Scotia, and Ontario. Many institutions reported negative impacts due to weather incidents including the heat dome in the PNW and record lows in Arkansas. Research focused on challenges in small fruit production are numerous within the NCCC-212. For example, several institutions are evaluating the impact of pests that are emerging in their state or region, or developing resistance to chemical controls. Research in the use of high and low tunnels for strawberry and caneberry production is ongoing in several states. Research on cultural methods to mitigate frost and freeze damage (e.g. in grapes) as well as flood damage is ongoing. Extension resources on mitigation and management of catastrophic weather events were published. Work is also ongoing at several institutions looking at soil disinfestation for strawberry production. In addition, several studies at Oregon State University illustrate the need to conduct long term research that has impactful findings that are useful to growers. Efforts to evaluate non-traditional small fruits as alternative crops are ongoing, including passion fruit, goldenberries, Juneberries, chokecherries as well as elderberry and Ribes. Finally, three stakeholder driven SCRI projects are currently underway in this group:

• The 2019 awarded Vac-CAP project (PD: Massimo Iorizzo, NCSU), with focus on the development of fruit quality traits in Vaccinium crops.
• The 2020 awarded SCRI CAP High-resolution nutrient vineyard management project (PD: Markus Keller, Univ. of Washington).
• The 2021 awarded Strawberry PIP-CAP project (PD: Mark Hoffmann, NCSU) focuses on the development and integration of controlled environment strawberry propagation technology.

The small fruit industries in both the US and Canada have benefited from release of new cultivars, ongoing research and improved cultural practices as a result of activities conducted by members of the NCCC-212. Almost all collaborative projects in the group entail extension components, disseminating the information to our stakeholders and industry partners.
