Abstract
A new cultivar of Apple tree, ‘Wildung’, is a late season cultivar that has shown to be hardy and productive for twenty-two years in east central Minnesota. The fruit is characterized by moderately firm, fine-grained flesh, with low acidity and a sweet taste with slight acid balance and rich overtones. The flesh of the fruit is very white and unusually slow to oxidize when exposed to air.
Description
Botanical Classification: Malus domestica.
Varietal Denomination: ‘Wildung’.
The present invention relates to a new and distinct cultivar of apple tree, botanically known as Malus domestica ‘Wildung’, referred to hereafter by its cultivar named, ‘Wildung’.
‘Wildung’ is a late season apple cultivar that has been shown to be hardy and productive for 22 years in east Central Minnesota. The fruit of ‘Wildung’ is characterized by moderately firm, fine-grained flesh with a sweet, rich flavor. The flesh is also notable in its resistance to oxidation when exposed to air.
‘Wildung’ was discovered in 1983 as a seedling by the inventors as Tree 47 in Row 14 of Block 6 in a trial plot in Ecelsior, Minn. The new apple arose from a cross designated AE 7022 made in 1970 between ‘Sharon’ (female parent) and ‘Connell Red’ (male parent). Both parents are unpatented.
Asexual reproduction of the new cultivar was first accomplished by means of budding and grafting by the inventors in Excelsior, Minn. The propagated progeny of ‘Wildung’ have been determined to be stable and are reproduced true to type in successive generations.
The following traits have been repeatedly observed and represent the characteristics of the new cultivar. ‘Wildung’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in temperature, day length, light intensity, soil types and water and fertility levels, without, however, any variance in the genotype. The measurements, observations and descriptions that follow describe plants grown outdoors and observed for twenty-two years in Excelsior, Minn.
-
- 1. ‘Wildung’ is a late season producer with fruit ripening occurring approximately between October 3rd and October 10th in Excelsior, Minn. Ripening time is similar or slightly later than ‘Haralson’ (unpatented) and slightly prior to ‘Regent’ (unpatented) and ‘Fireside’ (unpatented) and approximately two weeks after ‘Honeycrisp’ (U.S. Plant Pat. No. 7,197).
- 2. Fruit size of ‘Wildung’ ranges from 7.1 to 7.9 cm in diameter with a mean diameter of 7.3 cm. The fruit is smaller than ‘Connell Red’ and ‘Fireside’, which are commercial apples ripening at the same time of the season in Minnesota.
- 3. Fruit color of ‘Wildung’ is 65 to 85% red, occasionally with bronze-red tones, over yellow-green.
- 4. The fruit of ‘Wildung’ is firm to crisp with a fine to intermediate texture and oblate to globose in shape.
- 5. The flavor of the fruit of ‘Wildung’ is sweet and rich with low acidity, richer in flavor than ‘Connell Red’ and ‘Fireside’.
- 6. The storage life of refrigerated ‘Wildung’ fruit is 60 to 80 days.
- 7. The flesh of the fruit of ‘Wildung’ is very white and unusually resistant to oxidative browning.
- 8. ‘Wildung’ bears fruit annually and small, unripe fruit have not been commonly observed.
- 9. ‘Wildung’ has been shown to be hardy and productive for 22 years in east central Minnesota.
‘Wildung’ is distinguished from its parent ‘Connell Red’ in having smaller fruit size (‘Wildung’ is 7.1 to 7.9 cm in diameter whereas ‘Connell Red’ is 7.5 to 9.4 cm). The red overcolor of ‘Wildung’ is often more bronze than the overcolor of ‘Connell Red’. The flesh of ‘Wildung’ exhibits little to no browning when cut or otherwise exposed to air whereas flesh of ‘Connell Red’ will brown extensively. The fruit of ‘Wildung’ is slightly more acidic than the fruit of ‘Connell Red’.
‘Wildung’ is distinguished from its parent ‘Sharon’ in having white flesh color whereas ‘Sharon’ has cream flesh color. The fruit have a blushed red overcolor in ‘Wildung’ and striped red overcolor in ‘Sharon’.
The accompanying color photographs were taken in Excelsior, Minn. and illustrate the distinguishing characteristics of the new cultivar ‘Wildung’. The colors in the photographs are as close as possible with the photographic and printing technology utilized. The color values cited in the detailed botanical description accurately describe the colors of the new apple tree.
FIG. 4. provides a close-up view of the flesh of a mature fruit of ‘Wildung’.
The following is a detailed description of the new apple tree as grown under outdoor field conditions for twenty-two years in Excelsior, Minn. The color names and numbers refer to The 1995 Royal Horticultural Society's Colour Chart, London, England; except for general color terms of ordinary dictionary significance are used.
