Origin & Breeding History: 'APF-122' originated from a controlled cross conducted between 'APF-45' (female parent) and the unreleased proprietary variety 'A-2286' (male parent) in Clarksville, Arkansas in 2003. Resulting seedlings were germinated in a greenhouse and subsequently planted in a field in Clarksville, Arkansas in 2004. In 2005, 'APF-122' was selected for early primocane bloom and plant health, plant yield, and fruit firmness and flavour. 'APF-122' was subsequently asexually propagated, via root cuttings, commencing in 2005.
Tests & Trials: The detailed description of 'APF-122' is based on the UPOV report of Technical Examination, application number 20171702, purchased from the Community Plant Variety Office in Angers, France. The trial was conducted by the Bundessortenamt in Hannover, Germany in 2020 and 2021.
