Jonagored

A blood-red sport of Jonagold, found in 1980 at the top of a tree in Jos Morren's orchard at Halen, Belgium

History

Jonagored is a sport of Jonagold, the cross of Golden Delicious and Jonathan bred at the New York State Agricultural Experiment Station1. In 1980 Jos Morren found four blood-red apples at the top of a tree in his Jonagold orchard at Halen, in Belgium2,3. His US patent describes the fruit on that limb as already red at the beginning of September, while the rest of the block was still green, and turning blood red over three weeks1.

In 1981 he grafted twenty trees from the changed branch, and then a second generation from one of them; both kept the deep-red colour when they fruited, in 1983 and 19843. He applied for plant breeders’ rights under the name Jonagored in 19833, and for a US plant patent in October 1984; it was granted in April 19871. According to the firm, the English pomologist L. H. Clark found the variety distinct, uniform and stable in November 19853, the year the National Fruit Collection gives for its introduction4. The Morren firm promotes it under the registered trade mark Morren’s Jonagored3, which the European Union’s marketing standard for apples also lists for it8.

By the firm’s figures, European production rose from 159,135 tonnes in 1994 to 266,437 tonnes in 1998, led by Belgium, the Netherlands and Germany3. A Flemish agricultural news service put its production at 270 million kilos in 2006, when Morren was presenting a daughter strain, Jonagored Supra2. By the European industry’s figures it made up 2 per cent of Europe’s apples in 2025/26 and 1 per cent of the forecast for 2026/276. In Germany’s 2022 orchard survey it covered 435 hectares in Lower Saxony and 291 in Baden-Württemberg7.

The fruit

The patent describes Jonagored as like its parent in tree, leaves, flowers and fruit, except for its large, dark-red fruit, most with white lenticels, its dark-brown trunk and branches, darker than Jonagold’s, and the keeping quality of its fruit1. Where the original Jonagold is green to green-yellow with a large, striped orange-red flush, Jonagored is evenly flushed dark red5. The firm adds that the colour covers practically the whole skin, with little or no influence from the weather, and that the flesh is firmer and more acid than Jonagold’s3.

The fruit is large and round to round-conical, with a long, slender stalk1. The skin is tough, smooth and glossy, brownish red when young and blood red at maturity1. The flesh is white tinged with yellow, firm, fine, crisp and juicy, and sweet-sharp1; the National Fruit Collection describes it as creamy white, with a sweet, rich flavour4. At Halen the first fruit is picked at the end of September and the last before 15 October1; at Brogdale, Kent, it is picked in mid-October4. It keeps up to seven months in ordinary storage, and as well as Golden Delicious in cold storage1.

Growing

The tree is medium-sized, vigorous, upright and fast-growing, hardy, very productive and a regular bearer1. At Halen it flowers about the end of April, with Jonagold1. Its patent records no unusual susceptibility to pests or diseases1.

Uses

Jonagored is mainly a dessert apple, but it is also used in the kitchen and for juice1.
