Origin & Breeding History: 'Nevson' arose from the controlled pollination between 'Gala' as the seed parent and 'Hawkes Bay Red Delicious' as the pollen parent. The initial cross was made in 1983 at Alexandra, New Zealand on the property of Southern Trees Limited. It was selected in 1987, with further plants being produced through subsequent vegetative propagation. The main selection criteria was to produce a variety suitable for local growing conditions.

Tests & Trials: The tests and trials for 'Nevson' were conducted at Prospect Road, Berwick, Nova Scotia during the 2009 growing season. A minimum of 10 trees were planted of both the candidate and reference varieties. Trees were spaced 1.23 metres apart in the rows and planted 4.5 metres apart between rows. The trees were planted in 2006 on M26 rootstock.
