What was accomplished under these goals?
We transplanted approximately 5,000 grape seedlings at the Fargo nursery from field and greenhouse crosses. Also, we micro-vinified grapes from 120 accessions that fruited in the Fargo and Minot nurseries. Organized sensory evaluation at nearby winery with key stakeholders. Selected seven accessions for number increase/advanced testing. Transplanted advanced selections and standards into field experiments at Horticulture research site near Absaraka, ND and a grower location near Dickinson, ND. 'Marquette' and 'Petite Pearl' have recently won numerous wine awards. However, field research over the past years has shown that both may not be very hardy in North Dakota. 'Marquette' and 'Petite Pearl' were trained to four training systems to compare growth and fruiting characteristics with hopes to discover a training system/management practices that will promote winter survival and high quality fruit production. 'Crimson Pearl' is a full sibling of 'Petite Pearl' that growers are becoming more interested in because of greater fruit yields. Microvinification of 'Crimson Pearl' and 'Petite Pear' was initiated using 12 different yeasts to understand sensory attribute differences. Post-Graduate student's research continues to evaluate environmental conditions responsible for cultivar and accession differences in acclimation. Results have shown that 'Marquette's' winter injury in comparison to 'Frontenac' and MN1131 occurred due to a delay in the acclimation process when air temperature and soil moisture increased after acclimation processes were initiated in response to shortened day length and reduced air temperatures. Thermal differential analysis is being used to test advance selections acclimation and deacclimation tendencies. Cultivar recommendations and management practices for North Dakota continue to be important issues for growers and winemakers. To address, the NE1720 cultivar trial will be initiated in collaboration with researchers at Minnesota, Nebraska, and South Dakota. In addition, two specialty block grants were funded to address cold-hardiness issues associated with management and active collaboration on two SCRI proposals directed toward addressing many of these issues will continue if funded. A change in knowledge: From the annual results of the grape cultivar trial initiated in 2004, growers and persons interested in growing grapes have learned that zone 4 cold hardy grape cultivars do not have equal cold hardiness and that training systems and other fruit management practices can greatly alter fruit ripening in these cultivars. A change in action: From the results of two training system and leaf pulling trials, growers are converting their vertical shoot positioning system (commonly used in California on V. vinifera cultivars) to the high wire cordon system. A change in condition: Recognition that Farm Wineries provide rural revitalization and an important economic impact is starting to slowly occur.

What was accomplished under these goals?
Transplanted approximately 5,000 grape seedlings between two nurseries (Minot and Fargo) from field and greenhouse crosses. Micro-vinified grapes from 37 accessions that fruited in the Fargo nursery. Organized sensory evaluation at nearby winery with key stakeholders. Selected six accessions for number increase/advanced testing. Transplanted advanced selections and standards into field experiment at Horticulture research site near Absaraka, ND. 'Marquette' and 'Petite Pearl' have recently won numerous wine awards. However, field research over the past years has shown that both may not be very hardy in North Dakota. 'Marquette' and 'Petite Pearl' were trained to four training systems to compare growth and fruiting characteristics with hopes to discover a training system/management practices that will promote winter survival and high quality fruit production. Graduate student research has evaluated environmental conditions responsible for cultivar differences in acclimation. Results have shown that 'Marquette's' winter injury in comparison to 'Frontenac' and MN1131 occurred due to a delay in the acclimation process when air temperature and soil moisture increased after acclimation processes were initiated in response to shortened day length and reduced air temperatures. Growth chamber trial results mimicked field trial results, which indicates that advanced selections could be evaluated prior to release in order to avoid major winter dieback issues associated with 'Marquette'. Cultivar recommendations and management practices for North Dakota continue to be important issues for growers and winemakers. To address, the NE1020 cultivar trial and a cultivar trial initiate in 2004 and expanded annually will continue. In addition, active collaboration on two SCRI proposals and an EPSCOR proposal directed toward addressing many of these issues will continue if funded.

Transplanted approximately 3,000 grape seedlings from 2013 field and greenhouse crosses into two nurseries. Germinating approximately 5,000 seeds from 2014 field and greenhouse crosses. 'Marquette' and 'Petite Pearl' have recently won numerous wine awards. However, field research over the past seven years has shown that 'Marquette' is not very hardy in North Dakota and early information with 'Petite Pearl' suggest hardiness issues as well. A study has been initiated to investigate four training systems and to compare these two cultivars with hopes to discover a training system that will promote winter survival of one year old wood. Cultivar recommendations for North Dakota continue to be an important question asked by growers. To address this question, research on the NE1020 cultivar trial and the cultivar trial near Absaraka established in 2004 will continue and if new cultivars become available, they will be added to the cultivar trial near Absaraka.

What opportunities for training and professional development has the project provided? Andrew Aipperspach completed his MS degree and research on grapes. John Stenger, Brittany Olson, and Jared Peterson are graduate students working on grapes. Dr. Koycu, a visiting scientist from Turkey, worked on a grape disease project. How have the results been disseminated to communities of interest? Presentations have been made during NDSU, SBARE, and NDGWA field days; ASHS and International Cold Climate Grape conferences; and the NDGWA annual meeting. I was also asked to do a webinar for the Northern Grape Project and have written a number of research summaries that have been utilized for regional presentations and publications in New York and Minnesota. I was invited to give a presentation to potential grape growers in Montana and to agronomic producers in North Dakota. What do you plan to do during the next reporting period to accomplish the goals?
Nothing Reported
Impacts
What was accomplished under these goals?
Interest in grape production is high, but few have any knowledge of production practices or cultivar differences. The variety trials at Langdon, Minot and Williston have demonstrated that few cultivars can withstand the open cold winters in the western part of the state or the reduced growing degree days of the northern part of the state and consistently produce fruit. Dickinson has given up on their variety trial since additional funding was not available, variety survival was low and the goals they set for the trial (growing table grapes organically) seemed unobtainable. This area also receives late spring freezing temperatures, which further hampers production. The variety trial at the Horticulture Research and Herman Arboretum site demonstrated the lack of winter hardiness for a number of cultivars promoted as very cold-hardy including ‘Marquette’, the University of Minnesota latest introduction.

OUTPUTS: Variety trials at five locations: Williston Research Extension Center (northwest ND), Carrington Research Extension Center (central ND), Langdon Research Extension Center (northeast ND), Northcentral Research Extension Center (north-central ND) and the Horticulture Research Arboretum (southeast ND), continue to increase the number of cultivars to evaluate and determine cold hardiness and adaptability to North Dakota conditions. Another variety trial established near Wyndmere, ND for the NE1020 multi-state grape wine variety evaluation had limited fruit production. A long-term weed control study using three cultivars to compare chemical and cultural weed management strategies and their effect on plant growth and winter survival has been initiated to compare data collected from a similar study at a poor growing location with the new location. A canopy management study continued at three grower vineyards. Grape breeding efforts have been initiated with approximately 6000 seeds in various stages of germination. Seedlings will be planted into the field for winter survival evaluation. Outreach: Presentations were made at the NDGGA research workshop and summer field day, at the NDSU Horticulture Research field day, and the NDGGA annual meeting. A state report was presented at the NE1020 Multi-state evaluation of winegrape cultivars and clones. I was interviewed for several news articles and two television clips on grape production and the grape breeding efforts at NDSU and the Specialty Crop Research Initiative grant on grapes that NDSU is a part of. PARTICIPANTS: Harlene Hatterman-Valenti (PI) provided oversight to the research including design, sampling, analyses, and reporting. She coordinated labor, equipment and vehicle needs to complete field sampling and analyses. Collin Auwarter, Research Specialist, contributed in coordinating field crews and dates, field sampling, data collection and entry, as well as data analyses and report writing. John Stenger, Ph.D. candidate, conducted field sampling, data entry and analysis, report writing, presentation of results.

The variety trial at the Horticulture Research and Herman Arboretum site demonstrated the lack of winter hardiness for a number of cultivars promoted as very cold-hardy including 'Marquette', the University of Minnesota latest introduction. The grafting trial with St. Croix finally showed differences. All vines on their own roots died back completely to the ground while those with V. riparia rootstock survived the winter with little dieback. This was the sixth year for this trial, with no differences the previous five years. The grape program has helped to increase the number of vineyards in the state by 35% from one-on-one meetings with potential growers as well as from information provided by NDSU in their decision making. Even though the grape and wine industry is in its infancy, similarities with the industry in Minnesota suggest an economic impact of over $36 million in 10 years.

Dickinson has given up on their variety trial since additional funding was not available, variety survival was low and the goals they set for the trial (grow table grapes organically) seemed unobtainable.

The variety trial at the Horticulture Research and Herman Arboretum site demonstrated the lack of winter hardiness for a number of cultivars promoted as very cold-hardy including 'Marquette', the University of Minnesota's latest introduction. The trial also showed that a moderately heavy crop load in conjunction with late fruit maturity and early freezing temperatures will cause dramatic dieback for moderately hardy cultivars such as 'LaCrescent', 'Summerset Seedless', 'Alpenglow', and 'St. Croix'. A cultivar from the Elmer Swenson collection (ES 12-6-18) has shown to be extremely hardy and productive, but the fruit has an unpalatable earthy taste that we have not been able to reduce or eliminate. The weed control trial showed that straw mulch increased soil water content throughout the growing season in comparison to the herbicide treatment. The straw mulch also reduced soil temperature fluctuations compared to the herbicide treatment, but does require annual straw renewal. No differences in winter survival have occurred for the three cultivars and four weed management methods to date.

Outputs
OUTPUTS: Activities: The number of cultivars in variety trials evaluated to determine cold hardiness and adaptability to North Dakota conditions continues to increase. The trials were conducted at three locations: Williston Research Extension Center (northwest ND), Carrington Research Extension Center (central ND), and the Horticulture Research Arboretum (southeast ND). Additional variety trials have been initiated at Dickinson Research Extension Center (southwest ND), Langdon Research Extension Center (northeast ND), and Minot Research Extension Center (north-central ND) with most of the effort placed on replacement vines for those dyeing from the first winter. Another variety trial has been established near Wyndmere, ND for the NE1020 grant through the Viticulture Consortium East. Most cultivars are identical to those planted the previous year in South Dakota and Nebraska for the NE1020 program. Evaluations to compare chemical and cultural weed management strategies for weed control in three cultivars and their effect on plant growth and winter survival continued the second growing season. Two identical trials at unique locations were initiated to evaluate grow tube and pruning methods effect on Prairie Star establishment. An economical impact survey has been initiated for ND. I have been asked to represent North Dakota State University and along with Greg Krieger, the NDGGA president, to provide survey information to address research and extension needs of the emerging cold-climate wine industry in the Northeast and Upper Midwest. I worked with NDGGA board members and ND State Representatives to get a bill passed during the last legislative session to fund grape research. Outreach: Presentations were made at the NDGGA summer field day at the Horticulture Research Arboretum; the NDSU Horticulture Field Day, the North Central Weed Science Society Annual Conference, the American Society for Horticulture Science Annual Conference, and the NDGGA annual meeting. PARTICIPANTS: Harlene Hatterman-Valenti (PI) provided oversight to the research including design, sampling, analyses and reporting. She coordinated labor, equipment and vehicle needs to complete field sampling and analyses. Collin Auwarter, Research Specialist, contributed in coordinating field crews and dates, field sampling, data collection and entry, as well as data analyses and report writing. John Stenger, M.S. candidate, conducted field sampling, data entry and analysis, report writing and presentation of results. TARGET AUDIENCES: Target audiences for this research included producers, university research and extension personnel, agricultural lenders and loan officers. PROJECT MODIFICATIONS: Nothing significant to report during this reporting period.
Impacts
Interest in grape production is high, but few have any knowledge of production practices or cultivar differences. The variety trial at Williston has demonstrated that few cultivars can withstand the open cold winters in the northwestern part of the state. This area also receives late freezing temperatures during the late spring, which further hampers production. The variety trial at the Horticulture Research Arboretum demonstrated the lack of winter hardiness with 'Marquette', the latest University of Minnesota introduction. The trial also showed that a moderately heavy crop load in conjunction with late fruit maturity and early freezing temperatures will cause dramatic dieback for moderately hardy cultivars such as 'LaCrescent' and 'St. Croix'. The weed control trial showed that straw mulch increased soil water content throughout the growing season in comparison to the herbicide treatment. The straw mulch also reduced soil temperature fluctuations compared to the herbicide treatment. However, no differences in winter survival occurred for the three cultivars and four weed management methods.

Outputs
OUTPUTS: Variety trials continue to increase the number of cultivars evaluated at three locations: Williston Research Extension Center (northwest ND), Carrington Research Extension Center (central ND), and the Horticulture Research Arboretum (southeast ND), to determine cold hardiness and adaptability to North Dakota conditions. Additional variety trials have been initiated at Dickinson Research Extension Center (southwest ND), Langdon Research Extension Center (northeast ND), and Minot Research Extension Center (north-central ND). Four advance selections from the University of Minnesota (MN1189, MN1220, MN1235, and MN1285) as well as one selection from a private breeder (TP 34-1-7) and a named cultivar from another private breeder (Kay Gray). A weed control study using three cultivars was initiated to compare chemical and cultural weed management strategies and their effect on plant growth and winter survival. Another trial was initiated to evaluate establishment methods with Prairie Star. An additional study will be initiated under the objectives of a cooperative multi-state project; NE1020 to evaluate the viticulture characteristics and wine quality potential of clones of economically significant grape cultivars. Presentations were made at the NDGGA summer field day, which included the variety trial at the Horticulture Research Arboretum; two pruning clinics (Minot and Buffalo, ND) in the spring to demonstrate correct pruning practices; and the NDGGA annual meeting on weed control and a research update. I assisted with the production of a tri-fold brochure about the NDGGA. PARTICIPANTS: Harlene Hatterman-Valenti (PI), provided oversight to the research including design, sampling, analyses, and reporting. She coordinated labor, equipment and vehicle needs to complete field sampling and analyses. Collin Auwarter, Research Specialist, contributed in coordinating field crews and dates, field sampling, data collection and entry, as well as data analyses and report writing. John Stenger, M.S. candidate, conducted field sampling, data entry and analysis, report writing, and presentation of results. Three summer undergraduate student employees in which one was involved with an internship from the University of Puerto Rico. They participated in field sampling, processed samples, and assisted with plot maintenance. TARGET AUDIENCES: Target audiences for this research included producers, university research and extension personnel, and agricultural lenders and loan officers. PROJECT MODIFICATIONS: None.
Impacts
The most recent grape introduction from the University of Minnesota (Marquette) showed winter injury, with four of the 16 four-year-old plants in the variety trial at the Horticulture Research Arboretum dying back to ground level. Similar results occurred with ES 5-4-71, a promising white selection from the late Elmer Swenson. Cultivars at the Horticulture Research Arboretum yielded higher on a per plant basis compared to similar cultivars at the Williston Research Extension Center this past year. However, several fruit characteristics (berry size, juice pH, and juice TA) were similar.

Outputs
OUTPUTS: Variety trials have been established at three locations: Williston Research Extension Center (northwest ND), Carrington Research Extension Center (central ND), and the Horticulture Research Arboretum (southeast ND), for evaluation of cold hardiness and adaptability of grapes to North Dakota conditions. Additional variety trials are being planned for the Dickinson Research Extension Center (southwest ND), Langdon Research Extension Center (northeast ND), and Minot Research Extension Center (north-central ND). Three advanced selections, MN1220, MN1289, and MN1235, from the University of Minnesota will be added in 2008. A grafting study will be expanded to evaluate the potential for increased hardiness as well as the rootstock influence on fruit quantity and quality.

Impacts
Interest in grape production is high, but few have any knowledge of production practices or cultivar differences. The variety trials will be used to demonstrate cultivar differences and required production practices. Grape breeders from surrounding states have submitted material in order to evaluate cold hardiness and survival in North Dakota.
