Brief Summary of Minutes of Annual Meeting

Minutes of NCCC-212 Business Meeting

Virginia Beach, VA

Date: 10-25-16

Jayesh Samtani of Virginia Tech called the meeting to order at 8:05 a.m.  Kathy Demchak from Penn State University served as secretary, as Penn State will be the host institution for the 2017 meeting.

The agenda for this year’s annual meeting was reviewed.

Old Business.

Minutes:  The 2015 minutes were reviewed and approved as written.  Jayesh mentioned that articles cited for the report should be of the type found when searching a database, so readers can find the articles if they wish to do so.

Use of meeting time: It was generally agreed that we would like to use the meeting time for discussing state reports and coordinating future activities.  We find out what others are doing from the state reports, and discussions surrounding them have potential to result in future collaborations.  Presentations of reports also provide the opportunity for members who have more recently joined to learn about current work.  The overall conclusion was that members should send topics of interest for either collaborations or workshops to the chairs of the meeting each year few weeks ahead of the meeting, so that time for them can be included in the agenda.

CGC meeting: CGC members asked whether the CGC (Crop Germplasm Committee) meeting time and length should be changed to avoid needing to plan separate activities for non-CGC members or whether CGC meeting content should be made more relevant to other attendees.  No significant changes were planned though the CGC meeting next year will take place on the day before the formal NCCC-212 meeting.

Attendance by industry: The feeling of the group is that attendance by industry representatives is of value.  However, the stipulation is that all attendees, including those from industry, must bring a report that shares information with everyone.  There is the potential to increase collaborations for grants where industry partners may be able to play a role.  While industry attendees have generally been breeders from private companies, other types of businesses could be included.  NCCC-212 members should send Vance Baird information on industry contacts that may be interested in joining the group, as he can invite them.  They will not be official representatives, but would have access to on-line information such as by-laws and minutes and could attend the meeting.

New Business.

Attendance by University and USDA personnel: A list of past and future members should be maintained that includes research and extension personnel with small fruit and grape responsibilities.  A number of individuals who normally would have been participants were dropped off the NCCC-212 list when they didn’t attend recent meetings.

Upcoming meeting locations: This list of meeting locations for the last 10 years was reviewed.  Lisa DeVetter from Washington State (Mount Vernon) volunteered to host the 2018 meeting.  Kathy Demchak will ask Mary Rogers from the Univ. of Minnesota whether she is still willing to host the meeting in 2019, as Mary had been willing to host at the time of the 2015 meeting. This would bring the meeting back its home Northcentral region after being held elsewhere for a number of years.

Time of the annual meeting:  Points made were that if the annual meeting were held earlier in the fall, there would more time for development of collaborations and grant submissions for the ensuing year; however, it was determined that this would leave insufficient time between field data collection and the meeting.  Delaying the meeting time could be helpful in years when the project renewal is due, as this would allow more time between meeting authorization and the meeting itself in order to obtain travel approvals from attendee’s Experiment Stations.  

2017 meeting at Penn State:  Kathy Demchak asked whether attendees would prefer to have the meeting at the same location as in 2007 or somewhere closer to downtown State College and campus.  It was agreed that closer to campus would be preferable as long as any increase in the hotel rate was reasonable.  The 2017 meeting at Penn State will be held from Tuesday, Oct. 24 through Thursday, Oct. 26 2017.

Project renewal.  The group thanked Elina Coneva for her work on the project renewal. 

Lisa DeVetter motioned to approve the meeting minutes from last year.  Pat Moore seconded.  The minutes were approved and the meeting was adjourned.

Appended section: Impact Statements:

Objective 1

(Alabama) The fruit industry in Alabama is provided new knowledge on the performance and production systems of previously underutilized high-value specialty crops.

Two commercial vineyards in Alabama were certified to cultivate the newly bred grape selections, showing resistance to Pierce’s Disease.

(Arkansas) Baby Cakes™ (APF-236T) blackberry, a dwarf blackberry will enter the market this winter. It has been developed cooperatively with Fall Creek Nursery as a part of their ‘Brazelberries” line of garden plants.  FCN has since sold this product line to Star Roses, so it will marketed by this new owner. This is a result, as well as ‘Sharon’s Delight” (APF-132) (licensed in Japan), of breeding in the area of reduced internode and dwarf plants in blackberry. These are both home garden products, but this altered architecture will be utilized in commercial berry breeding and potentially useful in the substrate production area that is growing in practice with caneberries in the world.

(Arkansas) Major increases in primocane-fruiting blackberry cultivars has occurred in recent years, and this late summer to fall crop has become a component of the domestic blackberry marketing season. The production is for both the shipping and local markets.

(Arkansas) The wine grapes ‘Opportunity’ (A-2245) and ‘Enchantment’ (A-2467) were released in 2016. ‘Opportunity’ is a white vine cultivar, derived from ‘Cayuga’ and ‘Semillon’ mainly, and has shown good production over the years and good wine quality. ‘Enchantment’ is a red cultivar that combines multiple species. In grapes, the impact is much less than blackberries. 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.

(Maryland) The use of low-tunnel system in breeding program has resulted in a much longer season for evaluation, a greater ability to observe potential fruit yield and quality, and the ability to evaluate and select for resistance or tolerance to several pests and abiotic stresses sequentially rather than simultaneously, an advantage when the presence of one stressor impairs a breeder’s ability to evaluate for one or more other stressors.

(Multi-state- Oregon, Maryland, South Carolina) We deposited in a public database 3,507 raspberry gene sequences and 351 SSR markers. Raspberry breeders and geneticists worldwide will use them to map important traits.

(Multi-state-Oregon, British Columbia, North Carolina); A high-quality annotated genome sequence of black raspberry and transcriptome sequences from diverse plant tissues were developed and made public. This will serve as the reference genome for Rubus crops (red and black raspberry, blackberry). The reference genome with gene annotations from the transcriptome sequencing provides researchers with the ability to compare genomic regions and genes of interest across other members of Rosaceae and outside of the family. These comparisons provide opportunities to expand knowledge on how genes function in plants.

(Multi-state-Oregon, British Columbia, North Carolina): A marker for black raspberries has been identified that can distinguish susceptible from resistant individuals to aphids and two markers that can distinguish the Maine source from the Ontario and Michigan sources have been identified.

(Mulit-state-Oregon, British Columbia): ‘Sweet Sunrise’ and ‘Charm’ strawberry cultivars patented. ‘Marys Peak’ strawberry just released.

(Mult-state-Washington, Oregon) Small fruit plant sales in the Pacific Northwest (PNW) for 2016 were reported by plant propagators.  The PNW public breeding programs developed small fruit cultivars that comprise 72% of the raspberry PNW plant sales, 60% of the strawberry plant sales and 85% of the blackberry plant sales.  The value of production for 2015 in Oregon and Washington was $21.1 million for strawberries, $96.1 million for raspberries and $40.4 million for blackberries. 

(New Jersey) NJ99-204-1 has been named ‘Rutgers Scarlet’ strawberry and released in limited quantity in 2015 and licensed to two commercial nurseries.     

(New York) The Cornell strawberry breeding program focuses on developing varieties for perennial productions systems in cold climates. This production system is still prevalent in the upper Midwest and Northeastern U.S. and is especially important for many producers selling into the local food markets. ‘Archer’ strawberry variety will be released for the 2017 growing season.

(New York) Developing productive, high quality raspberry varieties for cold climate areas strengthens local economies and enhances the local food movement. Cornell varieties currently allow from growers in NY to produce raspberries from mid-June to November by utilizing varieties with varying production seasons and protected production systems like high tunnels and/or rain shields. Varieties are being developed with larger, better tasting fruit with longer shelf life to allow growers to access a wider market for their fruit.

(New York) Primocane blackberry breeding project has the potential to revolutionize blackberry production in cold climate areas. New varieties will provide growers the opportunity to introduce a new crop into their market by allowing the reliable production blackberries in areas where low winter temperatures prohibits this now.

(North Carolina) Two NC State short day strawberry genotypes are scheduled for release for growers in the Mid-Southern states. 

(Oregon-Postman) TobRSV virus was detected for the first time in Rubus at National Clonal Germplasm Repository.

(Oregon-Hummer et al.) Eighteen molecular markers have been identified that appear to be associated with one or more sources of resistance to aphids in the black raspberry source populations (ORUS 4304, ORUS 4305, and ORUS 4812).

(Oregon-Hummer et al) A blackberry fingerprinting set was developed that confirmed true-to-type 240 blackberries to the eastern and western blackberry populations.

(Oregon-Hummer et al) The 129 bp allele for marker Bx215 was found to be associated with remontancy inherited from a F. virginiana subsp. glauca accession collected in the Wasatch Mountains of Utah.

(Oregon-Finn, Strik) ‘Columbia Giant’ blackberry released and patent application filed in 2015.

(Oregon-Finn, Strik) ‘Columbia Sunrise’ blackberry released and patent application filed in 2016.

 (Oregon) ‘ORUS 289-1’ blueberry is being released for ornamental market.

(Oregon/Michigan): ‘Baby Blues’ blueberry submitted for patent

(Pennsylvania) Growers have information on blueberry and strawberry cultivar performance and disease and insect susceptibilities so they can make well-founded choices related to cultivars that they plan to grow on their farms. 

Objective 2

(Arkansas) In 2017, information on broad mite biology, scouting and a recommended miticide (Agri-Mek) is being added to state and regional pest management spray guides. Several newsletters have been distributed to growers in Arkansas and Pennsylvania informing growers of broad mites and the damage caused to blackberries.

(Maine) The video on ‘How to plant raspberries’ has over 41,000 views since posting and won National Winner, Communication Award, Video - National Association of County Agricultural Agents (2016)

(Maryland) The low-tunnel system shows great promise for commercial strawberry production up to nine months locally, even with varieties that were not developed locally.

(North Dakota) Through germplasm evaluation and enhancement trials, and examining practices for season extension and to avoid winter injury, profitable farm diversification practices and locally produced small fruit will become available in the state of North Dakota.

 (New York) The project on low-tunnels and day-neutral strawberries is developing information for growers about varieties and growing techniques that have not traditionally been utilized in the Northeastern U.S. Adapting varieties and annual production practices to a cold climate region requires more precise information on timing of plantings, plant types and varieties to minimize the risk to income due to weather, pests and low production output. This information is vital for growers to extend their production season, access wider markets and provide a more stable income stream.

(Oregon-Walton/Wiman).  Biotic and abiotic factors impacting development, behavior, phenology, and reproductive biology of Drosophila suzukii This work summarizes the important factors affecting D. suzukii impact on fruit, and helped provide guidance to develop management techniques to minimize egg-laying and survival. The overwintering and summer biology of this insect is described. This information helps to better target susceptible seasonal periods of this insect.

(Oregon-Walton) Impact of floral feeding on adult Drosophila suzukii survival and nutrient status.  This study addressed the impact of feeding on the survival and nutrient reserves of adult D. suzukii. We showed the importance of cherry blossoms and other alternate hosts to D. suzukii survival. These data have management implications for surrounding vegetation of this insect. These results illustrate the importance of adult feeding in enhancing survival and carbohydrate reserves among D. suzukii.

(Oregon-Walton/Wiman) Drosophila suzukii population response to the environment and management strategies. We determined that the initiation of the reproductive period of late dormant field-collected female D. suzukii ranged from 50-800 DD from January 1. This suggests that D. suzukii females can reproduce early in the season and are probably limited by availability of early host plants.  The newer DD population model can be used to examine stage-specific mortality effects of IPM practices from insecticides and parasitoids at the field level. We found that adulticides applied during the early season will result in the largest comparative population decrease. It is clear from model outputs that parasitism levels comparable to those found in field studies may have a limited effect on population growth.

(Oregon-Walton) Environmental cues enhance winter survival of Drosophila suzukii. To date, research conducted on D. suzukii cold resistance suggests that this species cannot overwinter in northern locations, e.g. Canada and Michigan.  Combining physiological investigations with RNA sequencing, we present potential mechanisms by which D. suzukii can overwinter in these regions.  This work may ultimately lead to more accurate population models that take into account seasonal variation in physiological parameters and development of better management strategies.

(Oregon-Walton) Population dynamics and ecology of Drosophila suzukii in Central California. This study described the importance of alternate hosts and the impact of high temperature. The most significant finding from this work was that d. suzukii can lay eggs that can survive in fruit juices.  These eggs can further develop into larvae and cause additional infestation. We proved through this work the importance of field sanitation against D. suzukii.        

(Oregon-Walton) First exploration of parasitoids of Drosophila suzukii in South Korea as potential classical biological agents. Several of the South Korean parasitoid species were imported to the USA and have the potential for use in classical biological control and may contribute to the suppression of D. suzukii in the newly invaded regions.

(Oregon-Strik) Application of liquid calcium sources, using several commercially-available products within the recommended label rate of Ca as a foliar, targeted application to developing fruit did not increase the %Ca of blueberry, blackberry, raspberry, or strawberry fruit or leaves and had no impact on fruit quality. Growers are advised to not use these products at present recommended rates in these crops with a goal of improved fruit Ca and quality.

(Oregon-Strik) In floricane-fruiting blackberry we are developing cultivar specific sampling recommendations and standards to help growers better manage fertilizer programs optimizing use efficiency and plant performance.

(Oregon-Dixon/Strik) Weed management strategies, training time, and the cultivar being grown were found to affect many growth factors, yield, and nutrient and carbon content of trailing blackberry when grown in a certified organic production system, machine-harvested for processing. Weed control, using weed mat or hand-weeding, increased yield 19% and 61% over non-weeded plots, on average, in ‘Marion’ and ‘Black Diamond’, respectively. It is clear that weed control is critical in this type of blackberry. Only training in February is recommended if ‘Marion’ is grown, to minimize risk of winter cold injury. There was no training time effect in ‘Black Diamond’. Yields of the best performing organic treatments were comparable to those seen in conventional production showing promise for industry growth. However, the life of organically-grown ‘Black Diamond’ may be limited if it becomes infested with raspberry crown borer (Pennisetia marginata Harris), a pest that is difficult to control in this organic production system; only this cultivar was sensitive to the pest.

(Oregon-Dixon/Strik) In trailing blackberry grow in certified organic production systems, there was no impact of withholding irrigation after fruit harvest (August and September) saving an estimated 500,000 L·ha-1 per year. We are currently evaluating root system distribution in these cultivars and treatments.

(Oregon-Dixon/Strik) Despite the relatively low cost of a no weed control strategy in trailing blackberry, low yield significantly reduced net returns (gross fruit sales – weed management costs). The hand-weeded and weed mat management strategies increased net returns by 40% and 71% compared to non-weeded, respectively. Weed mat had a 22% greater cumulative net return than the hand-weeded treatment. Weed mat increased growth, yield, and net returns and appears to be an excellent option for weed management in machine-harvested organic trailing blackberry.

(Oregon-Strik) From 2006, the start of our study, through 2014, total blueberry harvested area in Oregon increased from 4,400 to an estimated 10,000 acres. Organic area in Oregon increased from an estimated 60 acres in 2006 to an estimated 1500 to 2000 acres in 2014. The phenomenal 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 estimated at $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.

(Oregon-Strik) Over 95% of the planted organic area in Oregon is estimated to be established on raised beds using weed mat mulch. In addition, the use of weed mat mulch in new conventional plantings in Oregon has increased from an estimated 10% of the acreage in 2006 to more than 80% of the new acreage from 2010-2014. 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).

(Oregon-Strik/Vance) In a long-term organic blueberry trial, weed presence increased as the planting aged and costs of weed management continued to increase with organic mulches whereas the weed mat had relatively low weed control costs throughout the product lifespan (5−7 years). The cumulative labor requirements to control weeds in the weed mat, sawdust, and compost+sawdust treatments were 270, 1085, and 1309 h/ha, respectively. Weed mat increased cumulative yield (years 2−8) 4% compared to the organic mulches. Even with the small increase in yield, weed mat was the most economical method of weed control, increasing net income 13% and 22% in ‘Liberty’ and ‘Duke’, respectively, compared to compost+sawdust mulch. 

(Oregon-Strik) Given the impact of the various organic production systems tested over 8 years, research is underway to assess the long-term impact of these practices on soil and plant nutrient status and yield. The goal is to develop nutrient management guidelines for organic blueberry production.

(Oregon-Skinkis). Results to date show that ‘Pinot noir’ is fruitful at basal buds and can produce sufficient fruit to meet target yields according to current industry yield standards. The greater the cane diameter, the greater the fruitfulness, suggesting that growers must not limit their cane selection at pruning to just pencil diameter canes. Also, results suggest that spur pruning may be a viable option for ‘Pinot noir’ vineyards, and spur pruning is typically a less costly pruning method than cane pruning and could result in cost savings to the grower. Information that we obtain about causes of 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 long term.

(Oregon-Skinkis) Our work provides an evaluation of rapid methods for mapping canopy leaf distributions, determining canopy density and estimating exterior leaf area in VSP canopies where heavy management, dense canopies with intertwining shoots and tendrils complicate traditional methods for measuring grapevine canopies in research. Methods outlined by this research provide researchers with a non-destructive means by which to estimate leave area and may increase accuracy in quantifying canopy metrics, and help in the interpretation of results from studies conducted in vertically hedged grapevines.

(Oregon-Skinkis) The statewide crop load project indicates that cluster thinning has less impact on quality than the vineyard site itself, and it is not consistent in achieving certain fruit parameters at harvest. 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. 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. Cluster thinning is conducted using manual labor, averaging 40 hours and $700-800/acre annually. If no thinning is required to achieve wine quality, a $700-800/acre savings can be realized, a lower dependence on labor, and there could be a 10-40% increase in yields. If growers can increase yields by a modest 0.5 tons/acre, this would increase profits by nearly $130,000 annually for a 50-acre vineyard.

(Oregon-Skinkis) This information serves as a physiological basis for further studies being conducted on crop thinning/yield management in the labs of the PIs. Results suggest that growers do not need to limit yield to ensure a healthy vine or return productivity of ‘Pinot noir’ under the growing conditions of western Oregon. Furthermore, these results suggest that additional fertilization is not required in the short-term when vines are cropped to full capacity. Another study (Statewide Crop Load Project) will be monitoring effect on nutrient status and vine growth productivity long-term.

(Oregon-Vance/Strik) New information being learned will provide table grape growers in the Willamette Valley, Oregon with cultivar recommendations for fresh fruit quality.

(Pennsylvania) Growers are better able to successfully establish blueberry plantings on soils that are not of the types traditionally used for blueberry production.  This is an important improvement since they struggle to successfully establish plantings in these locations. 

(Pennsylvania) K-12 teachers learned about various aspects of agricultural research as part of an “Ag in the Classroom” experience to assist in relating various subjects, in particular physics, biology and current events, through an Ag in the Classroom learning opportunity.

(Virginia) Many growers in Virginia and North Carolina are trialing ‘Ruby June’ strawberry in open-field production in 2016-17 growing season.

Objective 3

(Oregon-Zhao) The study on chitosan based microencapsulation of blueberry anthocyanin extracts provided new information about the technology for stabilizing blueberry anthocyanin extracts during ambient storage.

(Oregon-Zhao) Quantification of bioactive compounds and physicochemical property of berry fruit pomace provide baseline data for the selection of suitable pomace for developing various value-added applications.
