List of apple varieties

The Weilburger , a cultivar of the cultivated apple ( Malus domestica), was first described by Adrian Diel in 1799 . The apple, which belongs to the Borsdorf family , stands out thanks to its long shelf life and consistent taste without wilting. The variety is used as a table and commercial apple .

Origin and Distribution

J. von Aehrenthal published the oldest illustrations in 1833 in the pomological work “Germany's Pome Fruit Varieties”.

After that, the variety was presented in 1875 in the “Illustrirten Handbuch der Obstkunde”. Oberdieck , Lucas & Jahn suspect that the variety was a chance seedling and that the name comes from the place Weilburg (an der Lahn ), possibly the place of discovery or because it was widely cultivated in this area. In 1889 the Engelbrecht variety was listed in the work "Germany's Apple Varieties". Illustrations and sectional drawings of the variety are also presented by Eneroth in 1896 in the “Handbook of Swedish Pomology”.

In the meantime, the Weilburg apple was neither replanted nor mentioned in more recent fruit-related works for many decades. In 2009 the variety was found again through a search by the pomologists' association in the local press. Only one tree could still be found , in the district of Hünstelden . Meanwhile, rice has been extracted from this tree and new trees have been grown.

The Weilburger apple was chosen by the Hessen regional group of the pomologists' association as the Hessian local variety of the year 2016 .

Genetic studies indicate that it could be a descendant of the real Edelborsdorfers .

Fruit description

Fruit shape

The shape of the fruit is flat and round, moderately bulbous in the direction of the stem, with small to medium size. The cross-section of the fruit is irregularly round and shows three to five weakly pronounced edges.

Texture of the peel

The skin is smooth, supple and somewhat shiny, with a light yellow to straw yellow base color, which shows a washed out light red on the sunny side. There are numerous shell points , these are - partly on the sunny side - bordered in red.

Calyx pit

From the calyx side, the calyx pit is slightly sunk, with flat bulges that merge into weak edges. It show up varietal rust figures or flaky rust approach. The calyx itself is medium-sized and closed to half-open. The sepals touching at the base are moderately long and inclined inward. Their tips are curved outwards.

Stem pit

On the handle side there is the medium-deep, relatively wide handle pit, which is uneven to slightly bulging. The stem pit is finely fanned to scaly rusted. The medium-thick, woody-brown stem is short to medium-long and does not extend beyond the edge.

Tree description

Location and vulnerability

The variety is robust, hardy and sufficiently frost hardy ; however, open winds are preferred.

Growth and care

The Weilburger shows a tall and well-branched crown on a straight trunk . Well-branching and long shoots enable good fruit wood formation.

Maturity and yield

The apples are considered as winter resorts , they mature in mid-October and without loss of quality to April usable . The Weilburger produces abundant yields early and produces regular fruit.
