PotatoesUSA/SFA Chip Potato Variety Trials, Maine Trial Site
The PotatoesUSA/SFA chipping potato variety trials are national trials evaluating the performance of advanced chipping clones from US potato breeding programs. The advanced clones in these trials represent top breeding clones that are being considered for commercial release by each breeding program. These top prospects are tested at 10-11 US trial sites each year along with two standard chipping varieties, Atlantic (out-of-field chipping standard) and Snowden (storage chipping standard).
Paul Ocaya, Bruce MacFarline, and student worker harvesting potato variety trials, Presque Isle, ME
Measuring tuber sugars with a YSI2700 Select, Presque Isle, MEYield, vine type and maturity, tuber appearance, tuber size profile, external and internal defects, chip quality, specific gravity, and bruise susceptibility are evaluated each year. Samples are placed in storage to evaluated chip quality throughout the storage season. Yield and quality as well as storage season reports from the Maine trial site can be viewed and downloaded by selecting Trial Reports from the menu (on the left).
Beginning with the 2011-2012 storage season, chip color and tuber sugar profiles have been generated from 42 and 50F storage. These storage profiles can be viewed by selecting one of the storage temperatures under Storage Data in the left-hand menu and clicking on a variety name. Clicking on the temperature radio buttons switches the views of storage data for each. Printouts (as pdf's) can be made with the Print button on each page for variety and temperature.
Samples are sent to the Frito Lay plant in Dayville, CT just after harvest and again after 3-4 months of storage at 50F. In each case, Frito Lay provides a commercial evaluation of chip quality and defects incidence.
