Jonagold

Intersection of Golden Delicious x Jonathan

Jonagold is a cultivar of apple culture (Malus domestica). Commercially it is distributed under the name of the color mutant Jonagored and under the brand name Red Prince. Jonagold was grown in 1943 in the experimental station of the Cornell University, Geneva, New York, USA, Golden Delicious and Jonathan, and came in 1968 in the trade.

She is one of the most widely planted varieties in Central Europe. Mutants with a distinct red color, such as ' Jonica ', ' King ', ' Jonagored ', 'Ruby Star ', ' Novajo ', ' Red Prince ' and ' Jomured ' are preferred in cultivation. These mutants differ in their appearance in part from the typical Jonagold appearance.

Description

Fruit

The fruits are large and spherical to highly constructed, their height-width index is 0.88. Their color is sunny yellow, on the sunny side orange-red to bright strawberry red. The lenticels are seen as red stars, or bright dots. The cup is of medium size. The stem is medium thick and long. Seeds are irregularly formed.

The flesh is yellowish, loose, short and juicy, later it becomes soft. They are edible in October. Their taste is slightly sour - süßfruchtig.

The content of sugars and acids is moderate to high.

Tree

The plants have a strong and rather slender growth. The shoots are usually inserted flat, many long shoots will be formed. The leaves are large and boat-shaped. This variety blooms late and long and fruitful.

Cultivation

The species prefers warm locations. It prefers soils that are fertile and profound. Compared with frost flowers and wood are overly sensitive. The shelf life of Jonagold is very good. The fruits are hardly endangered by Windfall.

Jonagold is moderately susceptible to powdery mildew, scab and canker of fruit trees. As pollinator Jonagold is not suitable as a triploid variety.

Mutants

Widely used is the mutant Jonagored, which has a red color larger areas, and reaches as Jonagored in trade and Red Jonaprince (brand name Red Prince). Common mutants are ' Novajo '; ' Jonica ', ' Wilmuta '. These have a brighter red color than the basic form, but also somewhat lower yields.

The mutant ' Marnica ' is distinguished by its striking red color. Due to their very juicy pulp it is often used for the production of apple juice. In Germany, the mutant is grown, for example, because of their high yield in the northern German fruit growing.
