Origin & Breeding History: 'Saffron Gold' originated from a cross conducted in 2008 between 'Baby Boomer' and 'Piccolo', at Tuberosum Technologies Inc. breeding program in Broderick, Saskatchewan. 'Saffron Gold' was selected in 2010 for its positive agronomic characteristics and resistance to various diseases.

Tests & Trials: The comparative trial for 'Saffron Gold' was conducted by Global Agri Services 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.
