Origin & Breeding History: 'UCD Valiant' originated from a cross conducted in 2011 in Davis, California. The cross was made between the variety 'Merced' and the proprietary male parent '07C092P003'. 'UCD Valiant' was selected for asexual propagation in 2012 based on yield, resistance to bruising and post-harvest deterioration, fruit appearance, and reduced runner production in coastal areas.

Tests & Trials: The comparative trial for 'UCD Valiant' 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.
