NY 55140-19
type: Culinary, Cider, Dessert, Jelly, Pie, Sauce
synonyms: Liberty
identification: Medium to large in size, the apple varies in shape between conic and round. Base skin colour is yellowish-gold washed to 90% with bright red marked with darker red stripes. The stem is very short and stout. Look for small sunken dots pocking the surface. A waxy, silver bloom develops on the surface when the apple is ripe.
characteristics: The flesh is yellowish, crisp, juicy and pleasantly sweet. Coarse-grained. Slightly astringent with a flavour of white wine.
uses: Intended as a fresh-eating apple. Also good in pies and sauces. A favourite among cider makers.
origins: Bred for disease resistance, this variety was developed by Robert Lamb at the New York State Agricultural Research Station in Geneva, New York (U.S.A.). The flower parent was a
Macoun to which pollen from an experimental cultivar (Purdue 54-12) at Purdue University in Indiana was applied in 1955. From this, 261 seeds were germinated and from these one seedling – NY 55140-19 – was selected for propagation and further monitoring in 1964. It was subsequently introduced by the New York State Fruit Testing Cooperative Association in 1974.
cultivation: Vigorous and upright spreading. Partial tip bearer. Produces annually with heavy crops, but needs to be thinned in order to get proper fruit size and prevent fruit drop prior to harvest. Fruit left to ripen too long develops an unpleasant taste.
cold storage: Keeps up to two months in cold storage and improves with time.
vulnerabilities: Highly resistant to scab and mildew, somewhat resistant to blight and rust. Susceptible to powdery mildew.
harvest: Ready for harvest starting at the beginning of the fifth period.
notes: The name Liberty was proposed by Bernadine Aldwinckle at the Entomology and Pathology Department at the Geneva (U.S.A.) Research Station to not only denote its freedom from diseases, but also to uphold the tradition of naming cultivars developed at Geneva after New York place names. The town of Liberty is about 160 kilometres northwest from New York City.
