Origin & Breeding History: 'Red Emmalie' originated from the Karsten Ellenberg breeding program in Barum, Germany. It is the result of a hybridization conducted in 2003 between the varieties ('La Ratte' x 'Baltica') and ('Highland Burgundy Red' x 'Huamantango'). The seed from the cross was planted in a greenhouse in 2004 and the resulting tubers were planted in the field in 2005. 'Red Emmalie' was selected in 2005 for its agronomic characteristics and resistance to various diseases.

Tests & Trials: The comparative trial for 'Red Emmalie' was conducted during the growing season of 2015 in Drummond, New Brunswick. The trial consisted of a single, 18.5 metre long row containing 60 plants spaced 0.3 metres apart for each variety. The distance between rows within the trial was 0.9 metres. Observations and measurements were taken from 10 plants, or 10 parts of plants, of each variety. Mean differences were significant at the 5% probability level based on a paired Student's t-test.
