Origin & Breeding History: 'Dakota Ruby' (Experimental number ND8555-8R) originated from a cross between 'ND7188-4R' and 'ND5256-7R' conducted in 2001 as part of a breeding program at North Dakota State University. 'Dakota Ruby' was selected in 2003 for its positive agronomic characteristics and resistance to various diseases.

Tests & Trials: The comparative trial for 'Dakota Ruby' was conducted by Global Agri serices Inc. during the growing season of 2016 in Drummond, New Brunswick. The trial consisted of a single, 19.5 metre long row containing 65 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.
