Discussion: No changes suggested
Move to approve: Mercy Olmstead
Seconded: Chad Finn
Vote = unanimous
Discussion on how the new executive committee is being comprised.
Suggestion: William Baird
In the past there was a four-member Executive Committee:
Past Chair (host from last year's meeting)
Current Chair (current meeting site host)
Vice Chair (next year's host)
Secretary (host 2-years out)
Post 2014 – 2015:
Past-Chair (last year’s meeting Chair): Kim Lewers
Chair (last year’s Reporting Secretary): Bernadine Strik, Chad Finn and Bob Martin
Recording Secretary (next year’s convener/host): Elina Coneva
TBD: Jayesh Samtani/Andrew Jamison
Maybe at next year’s meeting we should determine which pattern we want to maintain into the future.
The deadline for Annual Report submission is 60 days after the meeting. Send the state reports to Chad.
Future meetings
2015
The 2015 meeting will be held in Auburn, Alabama. The meeting will be led by Elina Coneva at Auburn Univ. The group proposed the period of October 19 to October 21 as the most preferable meeting time and the best format would be to have a two days meeting with 1.5 days for state reports and business meeting, and half a day for a field trip and grower visit. Additional day for the Small Fruit Germplasm Crop Germplasm Committee meeting should be included.
2016
Jayesh Samtani, VA, and Andrew Jamison, NS volunteered to host the meeting. Jayesh Samtani will check with the authorities, but the airport is about a 20 minute drive from the potential meeting site and there is a blackberry production close by. Andrew Jamison suggested a meeting in NS in 2016 might be a possibility.
Industry participation discussion: Bernadine Strik
Industry representatives are welcome to the meeting provided they will share a report. This year meeting space was limited and industry representation was limited to delegates who shared a report. Sharing a report is our requirement from the industry.
Move to adjourn the business meeting: Bernadine Strik
Seconded: Elina Coneva

NCSU Strawberry Breeding Program: 18 advanced selections were trialed across NC. Fields suffered significant plant loss to anthracnose, however, 2 selections looked good. NCS 10-156 is an early genotype that has uniform fruit with excellent flavor, rich red color and consistently good yields; a potential Sweet Charlie replacement. NCS 10-038, potential Chandler replacement, with high yields, firmer fruit and its more uniform production across the season. NCS 10-156 going to on-farm trials this fall.
NCSU Breeding for resistance to plant pathogens. Resistance to anthracnose foliar infections: Evaluated 18 genotypes for resistance to latent foliar infection by C. acutatum and C. gloeosporioides. Anthracnose crown rot resistance: Genotypes were also screened for resistance to crown rot by C. gloeosporioides. Little correlation was seen between foliar and crown resistance phenotypes, suggesting resistance to Colletotrichum species may be shared within common tissue types but inherited independently between tissue types. Seedlings from OP advanced selections were inoculated 5-6 x with C. acutatum and C. gloeosporioides under conducive disease conditions. 68 survivors showed no crown wilt and represent the top 1% resistant genotypes.

- Small fruit plant sales in the Pacific Northwest (PNW) for 2013-2014 were reported by plant propagators. The PNW public breeding programs developed small fruit cultivars that comprise 60% of the raspberry PNW plant sales, 62% of the strawberry plant sales and 72% of the blackberry plant sales.
- ?Cascade Harvest? was released as a productive, machine harvestable, Raspberry bushy dwarf virus resistant, root rot tolerant cultivar with good flavor.
- ?Black Diamond? and ?Columbia Star? trailing blackberries are rapidly displacing ?Marion? blackberry which has been the standard for 40+ years. While ?Marion? still leads with acreage in production, ?Black Diamond? has been the most commonly planted cultivar for 10 years and in 2014 over 60% of the plants that were planted were either ?Black Diamond? or the brand new release ?Columbia Star? while ?Marion? was less than 2% of plant sales.
- The major impact of the small fruit breeding effort in Arkansas in plantings of released blackberry cultivars, totaling over 1 million plants for marketing season 2013-2014. Of these, approximately 500,000 are PF. This indicates that PF acreage is increasing and this late summer to fall crop is becoming a component of the domestic blackberry marketing season. Likewise just over 500,000 plants of Ouachita, Natchez and Osage were sold during this period, reflecting increased FF planting also. The production is for both the shipping and local markets.
- ?Draper?, ?Liberty? and ?Aurora? blueberries released in the past 10 years have become among the top blueberries planted worldwide
- Estimated 95% of Florida blueberry production acreage utilizes cultivars developed in this breeding program.
- ?Tillamook? strawberry was once again the most important strawberry planted in the Pacific Northwest. It has been #1, 2 or 3 in plant sales since its release 10 years ago. With its longer lived plants it is estimated to now account for 50% of fruit production in the Pacific Northwest.
- Univ. of Florida developed strawberries dominate the acreage in Florida which is the second biggest production area in the US and they have been widely around the world.
- The RosBREED project is generating DNA tests for disease resistance and fruit quality traits in strawberry that will speed variety development and lower costs, leading to better cultivarss for growers in a more rapid timeframe.
- Phenotyping in Florida was performed for several traits, and QTL detection is underway for resistance to Phytophthora cactorum and Colletotrichum gloeosporioides as well as for a number of fruit traits including fruit size and soluble solids. Graduate student Jack Roach has also worked collaboratively with Dr. Andrew Jamieson to perform QTL mapping of a major locus for resistance to Xanthomonas fragariae on LG 6D. Genomic selection methodology is being developed for a Florida population and we hope to have GS experimentally tested by next spring.
- Supercore strawberry accessions with desirable flowering patterns and disease resistance combinations in west-central Florida have been identified.
- Cranberry cultivars, advanced selections and breeding lines from Rutgers were evaluated for yield and fruit rot resistance from 2005 through 2013 at Long Beach, WA and Bandon OR. New plantings were established in Richmond BC in 2013. Several selections have had exceptional high production across all locations. Two high yielding selection were released in 2013 (Welker and Hains). Some selections have had consistently low field and storage rot. These will be used to test their suitability for the late season fresh fruit market.
- In grapes, the impact of the Arkansas breeding effort is much less although increased plantings of the new cultivars along with Jupiter and Neptune in a range of states in the east and Pacific Northwest are being made. These are mainly for the local market.
- Small fruits have lagged behind many crop species in the development of public genomics and marker resources. Our collaborations with public programs help lay critical groundwork for the development of molecular breeding tools, and for the better understanding of the inheritance of important traits in Rubus and Fragaria.
- Compared room temperature storage and refrigerated storage of red, black, purple, and yellow raspberry fruit to determine the storage temperature that best enabled a breeder to evaluate new raspberry selections. Fruit were evaluated for the rate of decay and the rate of juice leakage during storage. Choice of storage temperature for evaluation depended on the type of raspberry and the market for which the new potential variety is intended (harvested by consumer or sold in stores). For raspberry types with two seasons per year, we found that fruit from both seasons must be evaluated.
- The Walmart Foundation strawberry grant program has had a major impact on strawberry research in the eastern US. This research has attracted regional and local collaboration to study the effect of the production system on fruit quality and to determine if use of ?short-day? genotypes could further lengthen the local production season. Several NCCC212 members successfully competed for a grant from NIFA to study berry production in protected cultivation, including further study to optimize low-tunnel strawberry production.
- Preliminary results indicate the potential for growing table grapes under high tunnels in Arkansas
- Developed production recommendations and tools to increase production season and regional diversity of US strawberry production
- Conserving water resources by implementing additional driplines to increase irrigation efficiency in CA strawberry production.
- Reducing the risk of human health pathogens by developing a quick-dip test for listeria and salmonella and best practices for the farm.
- Increasing product value and economic returns to growers through expedited on-farm testing of Rutgers bred strawberry cultivars and using GDD models for planting and row cover placement in NC.
- Information on strawberry aphid in Ontario will be used to develop better pest management recommendations for growers and reduce the spread of aphid-borne viruses between and within fields
- Thus far, the first muscadine vines that have been transformed for enhanced disease resistance are in field locations in FL, MS, and the Virgin Islands. Partial seedlessness has been achieved and will be verified in 2014. Consumer responses to muscadine varieties are in its second year with C. Sims.
- Growers can use the molecular diagnostic tool to quickly and accurately determine possible D. suzukii (SWD) infestation in shipments. This quick diagnostic will result in improved market access and savings in shipping costs. (Walton & Wiman)
- The impact of a Matrix Projection Model that uses temperature-dependent life table data for SWD is that growers can use this tool to optimize treatments and it can also be used as a risk tool. (Walton & Wiman)
- Growers can determine risk to SWD infestation in berry crops (used raspberry as a model) based on landscape characters. (Walton & Wiman)
- We know the current status of parasitoid biocontrol, the first step towards long-term management for SWD. (Walton & Wiman)
- We are using our findings for temperature and populations of SWD as baseline information for the SWD population model, which will direct and refine management action by growers. (Walton & Wiman)
- We now have a clear delineation of information available for growers and scientists that will help to direct management and research action against the invasive Brown Marmorated Stink Bug (BMSB). (Walton & Wiman)
- Growers can use our descriptions of BMSB symptoms to determine when during the growing season BMSB attacked their crop. We have also for the first time described direct impact of BMSB on blueberry. (Walton & Wiman)
- Growers can use our results on the stylet ?probing? behaviors of BMSB to determine when during the day and growing season they will most likely be having damage by BMSB feeding. This work also shows typical climates where most severe damage is expected. (Walton & Wiman)
- We have new information that gives us a better idea of the nature of BMSB invasive characters ? key needs as we are currently experiencing rapid expansion of this pest in many production areas. (Walton & Wiman)
- Primocane leaf nutrient concentrations in trailing blackberry varied by type of blackberry grown and cultivar. Preliminary findings indicate that the present standards for some nutrients may need revision to help growers develop better nutrient management programs. (Strik)
- Weed management strategies affected primocane growth and floricane yield in an organic blackberry planting during the establishment years. Machine-harvested yield was lower or similar to what would be expected in a commercial conventional field of similar age, depending on cultivar. The initial cost of the weed mat was far less than the cost of hand-weeding during establishment. The results of the study indicate that weed control is beneficial during establishment of trailing blackberry and can be done successfully in organic plantings using hand-weeding or weed mat. (Strik)
- Fresh market blackberry cultivars grown at a certified organic farm varied in yield, fruit quality and plant nutrient status. In contrast, there appeared to be relatively little effect of fertilizer source in this two-year study. Organic growers appear to have varied options for fertilization of blackberry. (Strik)
- We have shown that blackberry plantings can be successfully established using drip irrigation and fertigation in an organic production system. (Strik)
- Leaf nutrient concentrations in blueberry varied by sampling time and often by cultivar grown. Preliminary findings indicate that the present standards for some nutrients may need revision to help growers develop better nutrient management programs. Cultivars may differ in nutrient allocation. For example, ?Draper? had significantly higher leaf %Ca than most other cultivars, but had lower fruit %Ca ? we will continue work to assess whether this is responsible for the fruit drop issue seen with ?Draper? in some production regions.
- From 2006, the start of our study, through 2012 organic blueberry area in Oregon increased from an estimated 60 acres in 2006 to 750 acres in 2011. The nearly 7-fold increase in organic area planted in Oregon can be attributed, at least in a large share, to our positive research findings. The farm gate value of organic production in Oregon in 2006 was $2.7 million (1% of fresh production x $1.56/lb.); this value increased to $8.4 million (9.5% of fresh production x $2.45/lb.). Organic fruit has increased grower price by an average of 20% to 50% compared to conventional. (Strik)
- Over 95% of the planted organic area in Oregon is estimated to be established on raised beds using weed mat mulch. We believe that our positive findings have had a significant impact on the establishment of weed mat mulch as a ?standard? production system in Oregon at present. Growers with weed mat use an average of 2 fewer strip herbicide applications per year than those with sawdust mulch, saving $100 per acre. During the 6 years of this study, the impact of this would be $280,000 (2,800 acres planted with weed mat x $100). (Strik)
- Feather meal fertilizer with 12x more Ca and 7xs more B than fish emulsion, increased soil Ca and soil and leaf B in blueberries. Use of fish emulsion which contained 3x more P, 100x more K, and 60x more Cu, resulted in higher levels of soil P, K, and Cu, as well as a higher level of leaf P and K. Fish emulsion also reduced soil pH. (Strik)
- Compost+sawdust mulch increased soil pH and organic matter and resulted in higher levels of many soil nutrients than use of sawdust alone and increased leaf K and B. Weed mat, in contrast, resulted in the lowest soil pH, increased soil ammonium-N, and reduced soil Ca and Mg, but its effects on leaf nutrients were variable. Fish emulsion, weed mat, and compost were generally the most favorable practices in terms of plant and soil nutrition. (Strik)
- By selecting cultivars with superior resistance to Phytophthora cinnamomi, growers may avoid yield losses associated with the disease. An integrated control program is required for cultural suppression of blueberry root rot disease. Organic production using highly susceptible cultivars in the presence of P. cinnamomi is difficult, and may not produce equivalent yields to conventional production. Improved plant performance in the presence of P. cinnamomi was observed in trials using cultivar resistance, gypsum, and widely-spaced drip irrigation lines. (Yeo/Sullivan)
- Agricultural and economic benefits of research on crop level and vine vigor suggest that reduced vine vigor (leaf area and yields) decreases canopy management costs (more than $700/acre in leaf removal, shoot thinning, hedging, crop thinning). This project is defining appropriate yields for Oregon Pinot noir growers to maximize profits without decreasing quality. Even a 0.5 ton/acre increase in yield could increase profits by nearly $100,000 annually for a 50 acre vineyard. (Skinkis).
- Knowing more about what causes Primary Bud Necrosis and low fruitfulness will allow us to provide growers with management practices to potentially adjust vine vigor and increase yield for more balanced growth and more sustainable yields. (Skinkis).
- The 1st phase of a trial to determine optimal levels of N, P, and K for ?Pinot noir? helped develop updated nutrient guidelines for industry to assess the vine health status for Oregon. Data are reviewed annually and guidelines updated and shared with industry. Growers have been able to alter their nutrient management programs accordingly. For example, we are finding that some nutrient sufficiency levels from California guidelines are too high for wine grapes in Oregon. This has led to more informed decision-making by growers and a more judicious use of fertilizers. (Skinkis)
- Our work on validating canopy quantification methods for hedged vine canopies aims to develop more efficient yet accurate methods for researchers to collect vine canopy measures. Protocols will be developed that are designed to be implemented by researchers and may be possible to mechanize in the future in order for a quantification of canopy size for understanding vine balance in physiological research and potentially be used in commercial settings that will allow growers to make more informed decisions in managing vine balance through pruning, crop thinning, etc. (Skinkis).
- More than 10 companies have been actively engaged as research participants in yield management trials on-site in their vineyards and wineries. They report having a higher understanding of the whole vineyard system, are much more observant in the vineyard, and are beginning to look at yield management differently. Some collaborators have begun to change their yield management practices in other blocks outside of their research blocks and consider the impact this is making on wines during different vintages. (Skinkis)
- Our work on yield management impacts on vine physiology of Pinot noir will serve as a physiological basis for growers to better understand how their cluster thinning practices may be influencing vine health and productivity. Over time, this information will help them determine if they would need to add more irrigation or fertilization to support larger yields than their current practices. (Skinkis).
- Understanding the mechanism of reduction of cluster ripeness heterogeneity and the role of seed in the ripening process would not only help develop innovative viticulture practices aimed to improve overall fruit quality, but also will promote the development of new genetic and breeding programs resulting in the identification of new clones suitable for uniform ripening. (DeLuc).
- Definition of fruit and wine composition is an important topic with potentially extensive applications by the industry, the metabolic approach developed here can provide insights into the contribution of fruit compositional variability to the wine complexity. (DeLuc).
- Information on SWD in Ontario has been used to develop better SWD management strategies for growers and maintain good yields of high quality fruit.
