On November 5th, Rogers and Clark greeted participants at the MN Landscape Arboretum in Chaska, MN. Attendees introduced themselves and oral reports were given by state, institutional, or company representatives. Reports were uploaded digitally on a shared drive prior to the meeting and research, industry, and extension activities were addressed for USDA (Corvallis, OR), North Carolina, Minnesota, British Columbia, Washington, Michigan, North Dakota, Oregon, and Utah. The business meeting was held following lunch on the same day.
On November 6th, attendees boarded a bus to tour and learn about grape growing, wine and cider processing in Minnesota. Stops included 1) the UMN Horticultural Research Center (HRC), 2) Sweetland Orchard, and 3) Winery at Sovereign Estate. A welcome was given at the HRC by Pete Moe, director of the University of Minnesota Landscape Arboretum and Gregory Cuomo, Associate Dean for Research and Graduate Programs for the UMN College of Food, Agricultural and Natural Resource Sciences. Matthew Clark and staff from the UMN grape breeding and enology program gave a tour of the winemaking facilities, kiwiberry and grape plantings at the HRC. We ended the day back at the MN Landscape Arboretum where we viewed a remote seminar given by Chad Finn on the St. Paul campus to honor his career and accomplishments in small fruit breeding.

Accomplishments
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 Vaccinium species 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. Collaborative projects are listed below by crop for each of the three objectives.

Impacts
- An overarching goal of the project is to give small fruit growers needed tools to adapt 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.
- Objective 1 - Develop improved small fruit germplasm through cooperative breeding and evaluation programs. (British Columbia/Canada/Dossett et al.) Winter damage in 2019 streamlined selection process in raspberries, and four promising selections are being propagated to advance to on-farm grower trials. (British Columbia/Canada/Dossett et al.) Blueberry program is young, but one promising blueberry selection looked is being propagated to advance to on-farm grower trials. (British Columbia/Canada/Dossett et al.) Work is progressing on evaluating wild raspberry germplasm from around the world to create an improved genepool for breeding (British Columbia/Canada/Dossett et al.) We are propagating clean stock of a very promising advanced day-neutral strawberry selection which will be sent for on-farm grower trials in 2020. (British Columbia/Canada/Dossett et al.) First network of trials for berry selections and cultivars across four Canadian provinces with standardized protocols for data collection to assess performance and potential. In 2019, the first round of exchange of raspberry and strawberry selections took place, and exchange of blueberry selections is anticipated in 2020. (North Carolina) Use of rapid testing for fruit quality evaluation saves time and labor costs for breeding programs. The pH and titratable acidity values from pocket sized digital meters were compared to those with an automated titrimeter across strawberry, blackberry, muscadine grape, and blueberry and found to be in agreement within 70-90% of samples. The meters require only use of a fruit puree, with or without dilution and were found to cut time needed for assays by 60%. The meters offer an accurate, portable and time saving method to evaluate large sample numbers. (North Carolina) The blueberry tissue culture facility at Castle Hayne has been re-established. Our aim is to rapidly propagate larger numbers of advanced selections for trialing with growers and other possible collaborators. (Multi-state/Plant Breeding/Finn et al.) ‘Hall’s Beauty’ trailing blackberry released and patented. (Multi-state/Plant Breeding/Finn et al.) Eclipse’ and ‘Galaxy’ early ripening, semi-erect blackberries released and patented. (Multi-state/Plant Breeding/Finn et al.) ‘Twilight’ (ORUS 4370-1) semi-erect blackberry released and patent application filed. (Multi-state/Plant Breeding/Finn et al.) Patent applications have been applied for two new blackberry cultivars. (Multi-state/Plant Breeding/Finn et al.) Six blackberry selections have been/are being propagated for grower trials. (Multi-state/Plant Breeding/Finn et al.) Eight new primocane fruiting red raspberry selections are being propagated for grower trials. (Multi-state/Plant Breeding/Finn et al.) For the ornamental market: ‘Echo’ (ORUS 289-1) remontant blueberry has been released and a patent application submitted. (Multi-state/Plant Breeding/Finn et al.) In the blueberry program, we have selections from these parents and crosses among some of the parents that show low or very low susceptibility to Blueberry shock virus. (Multi-state/Plant Breeding/Finn et al.) Six new selections of strawberries are currently in grower trials that will be harvested in 2019 or are being propagated for grower trial. (Multi-state/Plant Breeding/Finn et al.) ‘Sweet Sunrise’ strawberry cultivar was released in 2016 and is doing well as an early season cultivar for fresh or processed markets. (Multi-state/Plant Breeding/Finn et al.) ‘Charm’ strawberry cultivar was released in 2016 has had excellent yields of very good fruit. While mostly released as potential ice cream berry it has been popular for farmer’s market sales. (Multi-state/Plant Breeding/Finn et al.) ‘Marys Peak’ strawberry cultivar was recently released. It typically has great yields of large, with excellent fruit quality. Outstanding processing potential, high yields of large fruit borne on plants with an open architecture making the fruit easy to pick. (Multi-state/Plant Breeding/Finn et al.) Several strawberry selections have been identified that are superb for landscaping. (Multi-state/Clean Plant Program) We shipped 122 named cultivars or advanced selections to nurseries this past year, this was predominantly Rubus material. (Utah) We released our first selection ‘AggieBlue™ Rendezvous’ which has been distributed to two native plant nurseries in Utah, and should be available for limited commercial distribution as early as 2020. (Washington) Surveys of production and marketing needs of Pacific Northwest strawberry growers show that fruit quality is considered the most important trait across all locations, with disease resistance/tolerance as the second most important. Specific fruit quality traits of importance were external appearance free of defects, skin color, size, sweetness, firmness, and flavor, whereas phytonutrients, seed color, and low drip loss after freezing and thawing were less important. Plant stress tolerance was identified as less important for strawberry growers in all locations. (Washington) WSU 2166 red raspberry was released in 2018 and was named ‘Cascade Premier’. (Minnesota) New, disease resistant, cold-hardy grape cultivars are being developed to reduce external inputs and maintain profitability for the local/regional wine industry (Minnesota) New winter-hardy kiwiberry cultivars are being developed, a potential new specialty crop for MN for commercial and home gardeners
- Objective 2 - Develop practices for small fruit production tailored for climatic and market needs of growers. (North Carolina) Blackberry cane tipping is done to increase yields and keep plants shorter. Application of pro-hexadione calcium, a dose dependent growth retardant, was applied to plants over two years. The growth retardant did not affect shelf life or composition of Osage, Von, or Traveler and reduced cane and intermodal length. Yield and fruit size were slightly reduced with the growth retardant. Use of growth retardants may help reduce labor needs for tipping but will need to be tested to determine relative yield loss. (Oregon) Fruit firmness is a priority for fresh market blueberry production, and many products are sold to growers to increase firmness at harvest. Growers will save approximately $105/acre/year in product cost alone due to this research. (Oregon) There is a strong relationship between the number of viable seeds per blueberry and berry weight in several of the most commonly grown cultivars in the Pacific Northwest, which stresses the importance of good pollination and seed set as best management practices. (Oregon) Blueberry growers producing in a climate with warm summer day temperatures, cool night temperatures, and little rain during the harvest period are well suited to let fruit hang on the bushes to improve sugar to acid ratio and flavor with no loss in yield or overall quality. Having more days between harvests also increases harvest efficiency thus reducing labor costs. (Oregon) The common use of organic fertilizer sources with high K has increased leaf and soil nutrient levels reducing blueberry yield. To date, in this study in progress, some changes, such as a reduction in soil K have been relatively rapid and positive for plant health. Yield has increased across all treatments in 2 of the 3 growing seasons since switching fertilizer and mulch systems. (Oregon) Weed mat. Our recently published study on development of 10 blueberry cultivars from planting to maturity in two certified organic mulching/amendment systems illustrated the importance of mulch type and the possibility of mitigating a measured decline in soil organic matter under weed mat by adding a sawdust mulch layer underneath. To date, yield has been impacted in one of two harvest seasons, while plant growth has been significantly greater with the combination of black weed mat with sawdust mulch underneath. (Oregon) With reduced labor availability and higher labor cost, we are in the process of developing a reduced labor production system for ‘Mini Blues’ blueberry. Leaving ‘Mini Blues’ unpruned for 3 years has not resulted in lower yield or any loss in fruit quality and required 90% less time than the standard method to prune, a huge cost savings for growers. (Oregon) To date, pruning and alternate trellising in blueberry ‘Legacy’ has not impacted yield or fruit quality, but we expect that over time with additional years of study we will begin to see larger differences. (Oregon) Grape cluster thinning has less impact on fruit and wine quality than vineyard site and it is not consistent in achieving certain fruit quality parameters between years or sites. Project collaborators have confidently increased yields by 0.5 ton per acre annually without compromising quality. This has led to a 25% increase in yields, which can harness an additional $1500/acre in grape sales on average resulting in additional $2.3 million per year in farm gate value for Pinot noir grapes. (Oregon) Spur pruning in grapes is possible without causing loss in yield, fruit ripening, or fruit composition at harvest. Selecting larger canes at pruning can also allow for greater vine fruitfulness and yield potential. (Washington) In a spring-planted trial, both biodegradable plastic and polyethylene mulches led to a 43% yield increase in raspberries compared to the unmulched, standard grower practice. (Washinton) In a late-summer planted raspberry trial, biodegradable plastic mulches did not successfully overwinter. Polyethylene mulch overwintered and led to a 20 cm increase in primocane height. However, yield was the same compared to the unmulched, standard grower practice. (Washington) Populations of root lesion nematodes (Pratylenchus penetrans) increased under plastic mulches, but deceases in raspberry plant growth and yield have not been observed. (Washington) Increasing honey bee hive densities from 4 to 8 or 10 hives/acre increase honey bee visitation rate, fruit set, and other yield components in some cultivars of blueberry (e.g. ‘Duke’ but not ‘Draper’). Realization of these benefits require honey bee hives be of good and consistent quality. Furthermore, increased hive density will not remedy other management problems. (Washington) Application of commercial pheromones does not lead to increased honey bee vitiation and yield components in ‘Draper’ blueberry. (Washington) Soil organic matter content varies from 3-60% in commercial blueberry fields in western Washington. Some growers struggle to manage fertility in these fields due to unpredictable release of nitrogen through mineralization. (Minnesota) New environmentally friendly pest and weed management practices are being developed in perennial fruit to help growers maintain profitability and preserve availability of local fruit (North Dakota) North Dakota has some unique environmental challenges that must be overcome for successful small fruit production. Through germplasm enhancement and by examining practices to hastening ripening or extend the season and avoid winter injury, profitable farm diversification practices and locally produced small fruit will become available.
- Objective 3 - Explore the association between fruit constituents and human health impacts. (North Carolina) The NIR system provides a way to rapidly analyze blueberries for specific sugars while minimizing the number of samples that need to be run by high performance liquid chromatography. This experiment leverage preliminary data and method for the VacciniumCAP proposal. (North Carolina) Strawberries are a robust source of vitamin C, even after storage. (Minnesota) Chemical analysis on grapes can help optimize compounds known to have human health benefit (Minnesota) Chemical screening for kiwiberry can help reduce oral irritants and improve consumer acceptability
