Origin & Breeding History: 'Orangoutang' (experimental designation KAS 46) is the result of the cross made by Dr. A. D. Crowe in 1985 between 'Granny Smith' and the Kentville seedling S13-35-53 at the Atlantic Food & Horticultural Research Centre in Kentville, Nova Scotia. Preliminary selections were done by Dr. Crowe until his retirement in 1987. Seedlings from the original cross were planted in 1987. KAS 46 was selected by C. Embree, newly propagated and planted in a comparative trial in block 140 in 1999. Selection criteria since then were for precocity, fruit size, colour, volume of yield, storage traits and fruit quality characteristics.

Tests & Trials: Tests and trials were conducted at the Atlantic Food & Horticulture Research Centre in Kentville, Nova Scotia during the 2010 growing season. Trees were planted in a row with a 2.1 metre spacing between trees within the row and 6.1 metre spacing between the rows. There were 5 trees of 'Orangoutang', 'McIntosh' and 'Northern' Spy' and 4 trees of 'Empire'. Trees of 'Orangoutang', 'McIntosh' and 'Empire' were on M26 rootstock while 'Northern spy' was on C655 rootstock.
