Origin & Breeding History: 'Wakefield' arose as the result of crossing 'Lewis' (seed parent) with the unnamed selection, '86105M57' (pollen parent) as part of a planned breeding program of the New Zealand Institute of Plant and Food Research Limited in Motueka, New Zealand. The initial cross was conducted in a greenhouse in 1990 and the resulting seed was germinated and grown at Plant and Food Research in Motueka. A total of 115 seedlings were planted in the field in 1991. The original plant of the new variety was selected during the summer of 1993-94 (Southern Hemisphere) and coded 90352EK-6.

Tests & Trials: 'Wakefield' was tested in Richmond, British Columbia during the 2012 growing season. The trials consisted of 4 replicates of the candidate and reference varieties. Plants were spaced 0.6 metres between plants in the row and 2 metres between rows. There was a minimum of 12 plants per variety. Measured characteristics were based on a minimum of 15 measurements.
