J U L Y / A U G U S T 2 0 1 7 12 POTATO GROWER A number of potato research projects are being conducted by the excellent researchers in North Dakota and Minnesota. The researchers are focused on current and future issues affecting potato growers in North Dakota and Minnesota. However, the findings of these research projects are often far greater that our region because the results are often used throughout the United States and other countries. We thank all the grower cooperators for allowing research to be conducted on their farms, industry partners and the Northern Plains Potato Growers Association and Minnesota Area II Research and Promotion Council for their support of the important research. Projects are funded by many sources, including the Northern Plains Potato Growers Association, Minnesota Area II Research and Promotion Council, through state and federal grants and pri- vate industry. If there are any questions or if there is something you feel needs to be studied, please let us know. We look forward to seeing you at the Northern Plains Potato Growers Association Field Day at Larimore, Inkster, and Hoople, North Dakota on Thursday, August 24th. Minnesota Area II Research and Promotion Council will hold a field day on July 18th in Becker, Minnesota at the Sand Plain Research Farm. More infor- mation on the field days can be found at z.umn.edu/spud or search for NDSU Potato Extension in your web browser.

The objective of this study is to quantify glycoalkaloid composition among leaf and tuber tis- sue, and measure the genetic resistance of Colorado Potato Beetle feeding among several NDSU breeding entries. We are also coordinating one of the seven northern locations of the 2017 Potatoes USA SNAC Trials with cooperat- ing grower Oberg Farms in Hoople, North Dakota. In the 2017 SNAC trial, we are testing 12 entries for marketable yield, chip defect and overall chip merit score during eight months of storage at 45o and 48oF. At the Larimore, North Dakota research pivot with cooperator Hoverson Farms, we are growing 68 advanced breeding lines representing 10 Public US breeding programs. Tubers harvested from this trial will be tested for post-harvest processing (fry / chip) quality during eight months of storage at varied (38o, 42o, 45o, 48oF) storage 2017 Potato Field Re
