Variety Description

Variety used for comparison: 'Macspur'

Summary: 'Diva' is an apple variety which is suited for cider and ice cider production. The dormant one-year old shoots of Diva have a moderate number of medium sized lenticels, whereas 'Macspur' has many small lenticels on the shoots. The fruit of 'Diva' is oblong to oblong conical in shape and the skin has a moderate bloom, compared with 'Macspur' which has flat globose fruit with strong bloom on the skin. 'Diva' has a longer, thinner fruit stalk than 'Macspur'. The lenticels on the skin of 'Diva' fruit are significantly more prominent than the lenticels on 'Macspur' fruit. 'Diva' has globose-conical seeds, whereas 'Macspur' has conical seeds. 'Diva' matures slightly later than 'Macspur' and is resistant to scab (Venturia inaequalis), while 'Macspur' is susceptible to scab.

Origin & Breeding History: 'Diva' originated from crossing 'McIntosh' with the pollen collected from '9AR5T17', a scab resistant line at Agriculture and Agri-Food Canada, St-Jean-sur-Richelieu Research Centre, Quebec. The original cross was made in 1971. Since 1974 the selected seedling, which became the variety 'Diva', was tested for its hardiness, disease resistance, fruit quality, chemical composition and shelf life. After extensive testing it was planted and evaluated in replicated trials since 2000 under the experimental designation SJC7123-1 at Verger du Minot and l'Acadie Experimental Farm.

Tests & Trials: Test and trials for 'Diva' were conducted at the Agriculture and Agri-Food Canada l'Acadie research sub-station, Quebec, and at Verger du Minot, a commercial cider production facility. Trees of 'Diva' were planted in replicated trials in 2000, under the test name SJC7123-1. The variety was compared in the trials to 'Macspur', using 4 replicates of each variety in a completely randomized design. Both varieties were grafted on M26 rootstock, and the yield, fruit size and other characteristics were collected since 2003.
