Origin & Breeding History: 'Zina Red' (experimental designation STT 02-1664) originated from the cross between 'Symphonia', as the female parent, and 'Amorosa', as the male parent, conducted in 2001 at HZPC Research B.V., in Metslawier, The Netherlands. One of the progeny, designated as STT 02-1664, was identified in 2002 and subsequently tested in The Netherlands and other locations abroad. Selection criteria was based on yield, internal and external quality as well as disease and insect resistance.
Tests & Trials: The comparative trial for 'Zina Red' was conducted by Global Agri Services Inc. during the 2018 growing season in Drummond, New Brunswick. The trial consisted of a single, 21 metre long row containing 70 plants spaced 0.3 metres apart for each variety. The distance between rows within the trial was 0.9 metres. Observations and measurements were taken from 10 plants, or 10 parts of plants, of each variety.
