Tests & Trials: The comparative trials for 'ZF06-079' were conducted by Expert Agriculture Team Ltd., in Chilliwack, British Columbia during the 2015 growing season. The plots were planted in the spring of 2014 in a randomized complete block design. Each variety consisted of 3 replicates with 3 plants per replicate for a total of 9 plants of each variety. Plants were spaced approximately 60 centimetres apart within rows and 3 metres between rows. Measurements were taken from 9 plants or parts of plants of each variety. Mean differences were significant at the 5% confidence probability level based on a paired Student's t-test.
