Origin & Breeding History: 'UCD Warrior' originated from a cross conducted in the winter of 2011 in Davis, California. The cross was made between the proprietary female parent '08C123P001' and the proprietary male parent '07C092P003'. 'UCD Warrior' was selected for asexual propagation in 2012 based on resistance to pests, fruit firmness, flavour, size, resistance to bruising and post-harvest deterioration, yield in the first and second year of production.
Tests & Trials: The comparative trial for 'UCD Warrior' 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.
