Origin & Breeding History: 'APF-190T' originated from a controlled cross conducted between the two proprietary unreleased varieties 'A-2293T' (female parent) and 'APF-49T' (male parent) in Clarksville, Arkansas in 2004. Resulting seedlings were germinated in a greenhouse and subsequently planted in a field in Clarksville, Arkansas in 2005. In 2008, 'APF-190T' was selected for ripening time, fruit shape and quality, thornless plant, plant health, and primocane fruiting habit. 'APF-190' was subsequently asexually propagated, via root cuttings, commencing in 2008.
Tests & Trials: The detailed description of 'APF-190T' is based on the UPOV report of Technical Examination, application number 20171442, purchased from the Community Plant Variety Office in Angers, France. The trial was conducted by the Bundessortenamt in Hannover, Germany in 2020 and 2021.
