Jonagold

Jonagold /ˈɒnəˌɡld/ is a cultivar of apple which was developed in 1953 in New York State Agricultural Experiment Station of Cornell University's College of Agriculture and Life Sciences, a cross between the crisp Golden Delicious and the blush-crimson Jonathan. They form a large sweet fruit with a thin skin. Because of their large size they are now favoured by commercial growers in many parts of the world. Jonagold is triploid, with sterile pollen, and as such, requires a second type of apple for pollen and is incapable of pollenizing other cultivars. The Jonagored Apple, a sport mutation of Jonagold, was once covered under United States Patent PP05937,[1] now expired.
