Jonagold

Jonagold is a cultivar of apple, a cross between Golden Delicious and Jonathan which was developed in 1953 in New York. 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, now expired.

Jonagold has a green-yellow basic color with crimson, brindled covering colour.

The apple has a fluffily crisp fruit. It is juicy and aromatic and has a sweet-sour taste.
