Origin & Breeding History: 'Apache' originated from the Old Fargie Potato Breeding Company Ltd. private breeding program in Perth, United Kingdom. It is the result of a hybridization conducted in 2003 between the variety 'Stoma' and a seedling of Solanum phureja. The seed from the cross was planted in a greenhouse in 2004 and the resulting tubers were planted in a field during the spring of 2005. 'Apache' was selected in 2005 for its agronomic characteristics and resistance to various diseases.
Tests & Trials: The comparative trial for 'Apache' 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.
