OUTPUTS: A second year of work continued in the evaluation to determine the best performing genotypes of twenty one advanced selections of strawberry developed at the University of Wisconsin-River Falls over the last decade. For six selections, selections are being evaluated in randomized complete blocks of 80 plants each in a four replicate trial design at each of two University of Wisconsin research stations. These blocks are used to collect fruit production data as soon as uniformity and suitable densities are obtained. In addition, excess runner plants are used for further propagation to expand trials in future years of the best performing selections throughout Wisconsin. For other selections where runner production is inadequate and to assure availability of virus-indexed stock, a micropropagation program at the University of Wisconsin-River Falls is being established. Annual presentations have been presented to meetings for grower networks including the Wisconsin Fresh Fruit and Vegetable (WFFV) conference, the North American Strawberry Grower's Association annual conference (NASGA), and the Michigan Great Lakes Exposition. In addition, the sites have provided outdoor demonstrations of strawberry culture and development to classrooms involving diverse growers and the general public. PARTICIPANTS: Dr. Brian R. Smith, UW-River Falls, Dr. Robert Tomesh, UW-Madison, Dr. Brent McCown, UW-Madison, Judy Reith-Rozelle, West Madison Research Station, UW-Madison, Michelle Miller, CIAS, UW-Madison, Dr. Jim Luby, University of Minnesota, Dr. Gail Nonnecke, Iowa State University, Wisconsin Berry Growers Association, Minnesota Fresh Fruit and Vegetable Growers Association, Nourse Farms, Massachusetts (a propagating nursery), twenty three commercial growers in three states. TARGET AUDIENCES: The Wisconsin strawberry industry serves as a high value cash crop and an economic stabilizer for more than 300 Wisconsin farm enterprises. The identification and development of new cultivars that are better adapted to the severity of Wisconsin climatic conditions, have superior pest resistances, and are both higher yielding with superior fruit quality promises to expand the productive capacity in Wisconsin. Such expansion is necessary to meet potential demands for locally produced fruit as well as to improve the use of the high value strawberry crop as an economic driver in rural communities. PROJECT MODIFICATIONS: Nothing significant to report during this reporting period.
Impacts
Performance of the six advanced hybrid selections generated in the program at UW-River Falls (RF) was evaluated in replicated plots at two Wisconsin locations and compared to standard commercial cultivars used as controls. The RF hybrid selections have performed among the best in regards to large average fruit size. In addition, a few of the RF selections have shown the greatest total yields.The maturity ranking depended on the selection and ranged from early midseason to late season. Collaborators assisted in the multi-location evaluations of advanced selections including Dr. Jim Luby (three locations in Minnesota) Dr. Gail Nonnecke (Iowa State University Experiment Station), and commercial growers in three states (fifteen in Wisconsin, six in Minnesota and one in Michigan). Cooperation from the growers networks in four states has also been critical. For future work, thirty-five new selections from previous hybridizations representing six different parentage families were chosen for continued evaluation and placed in replicated trial plantings; in addition to the production, planting and early evaluation of new hybrids (over 120,000 seedlings)in replicated plots continues.

OUTPUTS: Twenty one advanced selections of strawberry have been developed at the University of Wisconsin-River Falls over the last decade. Further testing and evaluation is needed to determine the best performing genotypes. For six selections, 160 plants were planted in randomized complete blocks of 80 plants each in a four replicate trial design at each of two University of Wisconsin research stations. These blocks are used to collect fruit production data as soon as uniformity and suitable densities are obtained. In addition, excess runner plants are used for further propagation to expand trials in future years of the best performing selections throughout Wisconsin. For other selections where runner production is inadequate and to assure availability of virus-indexed stock, a micropropagation program at the University of Wisconsin-River Falls has been established. This year, presentations were presented to meetings for grower networks including the 2009 Wisconsin Fresh Fruit and Vegetable (WFFV) conference, the North American Strawberry Grower's Association annual conference (NASGA), and the Michigan Great Lakes Exposition. In addition, the sites provided outdoor demonstration classrooms for educating diverse growers and the general public. PARTICIPANTS: Dr. Brian R.

Impacts
Performance of the six advanced hybrid selections generated in the program at UW-River Falls (RF) was evaluated in replicated plots at two Wisconsin locations and compared to standard commercial cultivars used as controls. The RF hybrid selections showed the following performance rankings: the highest average fruit size ranged from 12.3 to 18.8 grams and the RF selections ranked in the largest size categories. One RF selection had the highest total yield of 22,315 grams. The maturity ranking depended on the selection and ranged from early midseason to late season. Collaborators were identified to assist in the multi-location evaluations of advanced selections: Dr. Jim Luby has included UWRF strawberry selections in replicated trials at three locations in Minnesota (Excelsior, Grand Rapids, Morris); Dr. Gail Nonnecke has included the selections in replicated performance trials at an Iowa State University Experiment Station; and commercial growers have established the selections in their fields (fifteen in Wisconsin, six in Minnesota and one in Michigan) in conjunction with the WBGA (Wisconsin Berry Growers Association), the Minnesota Fresh Fruit and Vegetable Growers Association, and the NASGA. Thirty-five new selections from previous hybridizations representing six different parentage families were chosen for continued evaluation and placed in replicated trial plantings Spring hybridization involved the production of 239 hybrid families; over 120,000 seedlings were generated. In addition, 3,925 seedlings representing 96 hybrid families were planted for early evaluation in June 2010.

OUTPUTS: Twenty one advanced selections of strawberry have been developed at the University of Wisconsin over the last decade. Further testing and evaluation is needed to determine the best performing genotypes. For those plants where sufficient runner production was apparent, 160 plants were obtained and planted in randomized complete blocks of 80 plants each in a four replicate trial design at each of two University of Wisconsin research stations. One more growing season may be necessary to complete plant populations densities needed for performance data. These blocks will be used to collect fruit production data as soon as uniformity and suitable densities are obtained. In addition, excess runner plants will be used for further propagation to expand trials in future years throughout Wisconsin of the best performing selections. For those selections where runner production is inadequate and to assure availability of virus-indexed stock, a micropropagation program at the University of Wisconsin-River Falls also was established.

Impacts
So far the plots have been used in field strawberry plant establishment presentations to individual growers and grower groups. The project results, conclusions, and data collection will be completed when the plant density populations have established themselves to provide viable data.
