Variety Description

Varieties used for comparison: 'Redfree' and 'Gravenstein'

Summary: 'Cotton Candy' is an apple variety which has a drooping to weeping branching habit while trees of 'Redfree' are spreading and 'Gravenstein' has an upright habit. The branches of 'Cotton Candy' are at 90 degrees to the trunk while the branches of both reference varieties are at angles greater than 90 degrees. 'Cotton Candy' has some fruit bearing on the shoots and the spurs while both of the reference varieties bear fruit on the spurs only. 'Cotton Candy' has a medium number of lenticels on its one-year-old shoots whereas 'Redfree' has many and 'Gravenstein' has few. The leaves of 'Cotton Candy' are wider than both reference varieties. The length to width ratio of the leaf blades of 'Cotton Candy' is small whereas it is medium in 'Redfree' and large in 'Gravenstein'. The fruit of 'Cotton Candy' is very large while it is medium sized on 'Redfree' and large on 'Gravenstein'. 'Cotton Candy' fruit has a yellow ground colour, whereas 'Gravenstein' has a green yellow ground colour. 'Cotton Candy' has a moderate amount of streaked red overcolour while 'Redfree' has a very high amount of solid, dark red overcolour. 'Cotton Candy' has strong browning of the flesh, one hour after being cut, whereas it is weak in 'Redfree' and medium in 'Gravenstein'. 'Cotton Candy' fruit matures earlier than 'Redfree'.

Origin & Breeding History: 'Cotton Candy' originated from a cross conducted at the Agriculture and Agri-Food Canada Research Station in Kentville, Nova Scotia. The initial cross took place in the spring of 1991, between the parent varieties 'Redfree' and 'Oberle'. The resultant fruit produced from the cross were collected, their seeds dried, stored for about a month and then placed in a stratification media. Those seeds which germinated were grown and screened for susceptibility to apple scab. Resistant seedlings were kept and cared for in an extensive management approach. 'Cotton Candy' was identified in the field on August 23, 2001, by its sweet cotton candy-like flavour and its early maturation. The variety has been budded on Malling Merton 106 rootstock in the nursery at Agriculture and Agri-Food Canada Research Station, Kentville, Nova Scotia and will continue to be propagated by bud grafting.

Tests & Trials: Trials for 'Cotton Candy' were conducted at the Kentville Research Station of Agriculture and Agri-Food Canada in Kentville, Nova Scotia. Plots consisted of 5 to 6 five year old individually standing trees each of the candidate and reference varieties. 'Cotton Candy', 'Redfree' and 'Gravenstein' were planted on MM106 rootstalks.
