Origin & Breeding History: 'Kaido' originated from an open pollinated cross that occurred in Corvallis, Oregon, U.S.A. and was bred and developed by the breeder Dr. Maxine M. Thompson. The cross was made between a female parent variety, designated '#22-64', and an unknown male parent. The resulting seeds were collected and sown in Corvallis, Oregon, U.S.A. From the resulting seedlings, 'Kaido' was selected as a single plant in 2007 based on its plant vigour; fruit size, appearance, taste, yield and early maturity. 'Kaido' was first propagated by hardwood stem cuttings in 2008 in Corvallis, Oregon, U.S.A.

Tests & Trials: The comparative trial for 'Kaido' was conducted in the field and examined during the summer of 2018 at BioFlora Inc. in St. Thomas, Ontario. The trial included a total of 15 plants each of the candidate variety and reference variety 'Hoka', 7 plants of the reference varieties 'Tana' and 'Borealis' and 10 plants of the reference variety 'Chito'. All plants were grown from rooted cuttings and transplanted in the field on June 9, 2016. Observations and measurements were taken from 10 plants, or parts of plants, of each variety at various times throughout the summer of 2018. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
