Katja , also Katy, is a variety of the cultivated apple Malus domestica .

description

The medium-sized apple is a striking red color. The basic color is initially a very light greenish yellow, which later changes to a light yellow. Above it, often almost completely, it is covered in a bright purple red. At the calyx and stem pit, a silver-white veil can appear over the surface color. The lenticels are small and inconspicuous and colored white or light yellow. The pulp is white with green parts. The apple is bellied. It can be uneven or five-humped on the edge of the calyx pit. The shell is hard. The usually crooked stalk is medium to thick and long.

Katja's taste, however, is not very pronounced, is sour and refreshing. Freshly harvested, the apple is extremely juicy. The apple is used as a table apple , for cooking, for juice and cider production. The juice obtained from Katja has a slightly reddish-orange color.

Cultivation

Katja is comparatively hardy and is therefore also grown in northern climates. The apple is easy to grow, needs little care and is comparatively resistant to the most common apple diseases.

The diploid tree is a good pollinator variety, but it does not fertilize itself. Katja bears flowers for a comparatively long period of time and is therefore well suited for pollinating many other varieties. Katja grows faster than the mother variety Worcester Pearmain. Katja grows upright and spreads heavily on the numerous fruit shoots.

Katja is ready to be picked at the beginning of September and can be consumed from September to the beginning of October. Shortly after the harvest, the pulp begins to soften.

history

Katja was recruited at the Institute for Plant Breeding in Balsgård , Sweden (now part of the Swedish University of Agricultural Sciences ) in 1947 , selected in 1955, launched in 1966, and finally given its name in 1968. It is common in commercial cultivation in the UK. In Central Europe, however, the apple could not establish itself on the market.

Katja (along with its parent strains James Grieve and Worcester Pearmain ) is one of eight apple varieties that have won the Scottish Gardenplant Award - a counterpart to the Royal Horticultural Society's Award of Merit , which is said to take into account Scotland's harsher climate.
