Suncrisp

SUNCRISP

Origin Rutgers Horticultural Research Farm, New Brunswick, New Jersey.
Parentage Golden Delicious x (Cortland x Cox's Orange Pippin).
Availability October through March.
Source Limited availability.
Quality Suncrisp is a very firm and crisp apple. Its texture is somewhat coarse and melting when eaten. It does not produce a lot of juice. The flavour is somewhat tart at harvest but mellows in storage.


Fruit:
Size Small to medium. Will require good crop load management to optimize fruit size. In trials in New Jersey it was found that Suncrisp produced best quality fruit when thinned to one fruit every 15-20 cm.
Surface Rough, similar to Cox's Orange. It tends to have more skin russeting than Golden Delicious, especially in the stem bowl. Somewhat irregular shape.
Ground Colour Yellow-green.
Over Colour Orange-red blush. Can cover as much as 50% of the fruit.
Flesh Colour Green-yellow.
Pressure 17-20 lbs pressure reading typical at harvest.
Harvest Season Over the past two years at Kentville the average harvest date has been October 18.
Storage Suncrisp is said to be an excellent keeper. It is reported to have good textural and flavour characteristics after five to six months of common storage at 1ºC. In limited storage of Cultivar Evaluation Trial (CET) fruit at Kentville Suncrisp has maintained texture and flavour until March in common storage.
Strains None identified to date.

Tree:
Vigour Semi-vigourous.
Habit Upright to semi-erect.
Precocity Very precocious.
Fruit Placement Well distributed throughout tree canopy on fruit spurs and terminals.
Bloom Period Late mid season with Golden Delicious.
Pollination Appears to be pollinated by most other varieties blooming at the same time.
Nutrition Unknown at this point.
Crop Productive. Can become biennial.
Synchrony Can be harvested in one pick.
Adaptation Suncrisp was planted in the CET in 1996 and has shown no problems with respect to adaptation to our conditions.
Disease Reaction Unknown at this point.
Insect Reaction Unknown at this point.
Rootstock At this point Suncrisp has only been grown on M9 rootstock in Nova Scotia. Although Suncrisp is semi-vigourous it is likely that more vigourous rootstocks will be needed under certain conditions in order to attain adequate tree size.

Comments:
Suncrisp is a promising variety that has been grown on a limited scale in Nova Scotia over the last three years. The information contained in this fact sheet is based on limited experience with this variety in our region.
