The fruit of 'DS3' has a medium to large eye whereas the fruit of 'Honeycrisp' has a small eye. The pattern of over colour on the fruit skin of 'DS3' is flushed, striped and mottled whereas the pattern of over colour on 'Honeycrisp' is a weakly defined flush with strongly defined stripes.

LEAF BLADE: outwards attitude in relation to shoot, medium to large length to width ratio, medium to dark green on upper side, serrate type two incisions of margin on distal half, absent or sparse pubescence on lower side
PETIOLE: small extent of anthocyanin colouration at base

FLOWER: begins flowering mid-season, dark pink on outer side at balloon stage, very large diameter with petals pressed into horizontal position, arrangement of petals is overlapping, stigmas positioned below anthers

YOUNG FRUIT: small extent of anthocyanin colouration
FRUIT: large to very large, small height to diameter ratio, conic shape, absent or weak ribbing, absent or weak crowning at calyx end, medium to large eye, long sepal, locules closed or slightly open in transverse section, late harvest maturity and eating maturity
FRUIT SKIN: absent or weak bloom and greasiness, yellow-green ground colour, very large area of over colour, medium red over colour distributed as flushed, striped and mottled, narrow to medium width of stripes, medium amount of area of russet around stalk attachment, absent or small area of russet on cheeks and around eye basin, many medium to large lenticels, medium to deep and medium to broad stalk cavity, medium to deep and broad eye basin

Origin & Breeding History: 'DS3' was discovered within a cultivated orchard located in La Cross County, Wisconsin, USA. Seeds from an open pollinated 'Honeycrisp' apple tree were collected in 1990 and planted in 1991. After a suitable growing period, 'DS3' was selected from surviving seedlings during 2002. Second generation trees were budded onto EMLA 26 rootstock and observed during 2009 and 2010 growing seasons. 'DS3' was selected for fruit size and high acidity when compared to 'Honeycrisp'.

Tests & Trials: Tests and trials for 'DS3' were conducted in 2017 and 2018 at Summerland Varieties Corp test plots, in Summerland, British Columbia. The trials consisted of 10 trees of 'DS3', grown on EMLA 26 rootstock, and 10 trees of 'Honeycrisp', grown on M9 rootstock. The trees were planted in 2014. Mean differences were significant at the 5% confidence probability level based on a paired Student's t-test.
