Origin & Breeding History: 'Donata' originated from a cross between L 96/739/677, as the female parent, and E 00/414/487, as the male parent, conducted in 2003 in Ebstorf, Lower Saxony, Germany. 'Donata' was selected in 2004 based on agronomic characteristics.

Tests & Trials: The comparative trial for 'Donata' was conducted by Global Agri Services Inc. during the 2019 growing season in Drummond, New Brunswick. The trial consisted of a single, 21 metre long row per variety. Each row contained 70 plants spaced 0.3 metres apart with an inter-row spacing of 0.9 metres.
