The southern part of the Hardangerfjord, Norway (lat. Keywords: flowering peach leaf curl Prunus persica Taphrina deformans yield Furthermore, ‘Harnas’ and ‘Riga’ could be considered for use in future breeding programs for this cool, mesic Nordic climate. However, looking forward, both ‘Riga’ and ‘Harnas’ may be suitable for commercial tunnel production and home gardens. We conclude that none of the cultivars tested are suitable for commercial production. ‘Riga’ was somewhat tolerant of peach leaf curl but flowered early. ‘Harnas’ fruit quality was excellent when compared with all other cultivars, but trees were extremely susceptible to peach leaf curl. Harnas yielded 6.93 kg/tree in 2010, but had very low yields in 2009 and no yield at all in 2011. The most consistent yielding cultivar was Riga with 5.74 kg/tree in 2009, 2.06 kg/tree in 2010, and 4.71 kg/tree in 2011. Peach leaf curl ( Taphrina deformans) was the main disease affecting production. In a cool, maritime Nordic climate, where fruit have been grown for many centuries, 13 early maturing peach ( Prunus persica) cultivars from northern European climates were evaluated over a 6-year period.
