Origin & Breeding History: 'Yoli' (experimental designation '104522') originated from a cross made in April 2005 at Sweet Darling Sales, Inc. in Watsonville, California, USA. The cross was conducted between the unreleased cultivars '1621' (female parent) and '1285' (male parent). 'Yoli' was selected on June 29, 2006 based on the quality and quantity of both the inflorescence and fruit. Asexually reproduced stolons have since been tested in California at low and high elevations.

Tests & Trials: The comparative trial for 'Yoli' was conducted during the summer of 2018 in Lavaltrie, Quebec. A minimum of twenty bareroot plants per variety were planted in double row raised beds in late April 2018. The raised beds were approximately 25 cm high by 32 cm wide and covered with white plastic. The plants were spaced 30 cm from each other in a staggered pattern and the rows were spaced 1.5 metres apart. There were 2 replicates. Measured characteristics were taken from 15 plants, or parts of plants.
