Origin & Breeding History: 'Glen Ample' arose from the cross SCRI7326EI by SCRI7412H16 made in 1978 at the Scottish Crop Research Institute in Invergowrie, Scotland. 'Glen Ample' was first selected from a single seed in 1981 for its outstanding combination of yield and size, brightness and fruit flavour. Initial evaluation was carried out at the Scottish Crop Research Institute and at Brogdale Farm, England.

Tests & Trials: Tests and trials for 'Glen Ample' were conducted at the Simcoe Research Station, Univeristy of Guelph, Simcoe, Ontario during the 2010 to 2011 growing seasons. Twenty four (24) plants of each variety were planted in 23 cm pots in the summer of 2010 using soil-less potting mix and were raised outdoors. That fall, dormant plants were moved into a cooler, kept cool for 6 weeks and transferred to a greenhouse in December 2010. Pots were spaced approximately 0.5 metres apart in the row and approximately 1.5 metres apart between rows. Fruit characteristics were observed in field trials conducted at the Atlantic Food and Agriculture Research Centre in Kentville, Nova Scotia during the 2011 growing season. Measured characteristics were based on a minimum of 10 measurements.
