Origin & Breeding History: 'DrisStrawSeventyNine' originated from a cross conducted in June 2012 in Santa Cruz County, California. The cross was made between the proprietary female parent '7R309' and the proprietary male parent '92T351'. A single plant was selected for asexual propagation via stolons in April 2013 in McArthur, California. In 2015, 'DrisStrawSeventyNine' was selected for flavour, shelf life, fruit size, and harvest time in Tapalpa, Mexico and underwent further testing from 2015 to 2019.

Tests & Trials: The comparative trial for 'DrisStrawSeventyNine' was conducted by Expert Agriculture Team Ltd., in Chilliwack, British Columbia during the 2022 growing season. The plots were arranged in a RBC design with 3 replicates. Each replicate consisted of 10 plants for a total of 30 plants of each variety. Plants were double offset row planted with approximately 30 cm between plants and 20 centimetres between the offset rows. Measurements were taken from 10 plants or parts of 10 plants of each variety. Mean differences were significant at the 5% confidence probability level based on a paired Student's t-test.
