Description

Botanical classification: Malus Mill.

Varietal denomination: ‘UEB 3375/2’.

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct cultivar of apple tree botanically classified as Malus Mill. and known by the varietal name ‘UEB 3375/2’. The new variety was discovered in the fall of 1999 in The Czech Republic. The new variety is the result of a planned breeding program between unpatented female parent ‘Topaz’ and unpatented male parent ‘Golden Delicious’. The purpose of the breeding program was to find a new cultivar with high disease resistance, high yield, and excellent fruit quality. The new variety exhibits similar Vf—resistance against scab to ‘Topaz’, but there is an absence of russeting in the stem cavity. The new variety exhibits a similar tree habit, yellow ground color of fruits, and long fruit stem to ‘Golden Delicious’, but exhibits a globose fruit shape, the absence of fruit russeting, and the presence of Vf—resistance against scab. The following characteristics distinguish the new variety from other Malus Mill. varieties:

    • Late, dessert-type, diploid variety
    • Trees are of medium vigor with a spreading habit
    • Fruit shape is globose with a slight ribbing
    • Stalk is long and medium thick
    • Russeting is absent
    • Ground color of the fruit skin is yellow
    • Overcolor is either absent or a very slight orange blush
    • Fruit flesh is firm, juicy with a harmonic sugar/acid content, and good flavor
    • Keeping quality of the fruits is very good
    • Vf—resistance against scab is present
    • Fruit of the new variety matures shortly after ‘Golden Delicious’

The new variety has been trial and field tested and has been found to retain its distinctive characteristics and remain true to type through successive propagations. The new variety has not been publicly available or offered for sale anywhere in the world before the filing date of the present application. The new variety is the subject of Plant Breeders' Rights Application Number 1505/MAL08641, filed Mar. 7, 2003, in The Czech Republic, and European Community Plant Breeders' Rights Application Number 2003/1436, filed Aug. 11, 2003.

DESCRIPTION OF THE DRAWINGS

The accompanying photographic drawings illustrate the new cultivar, with the color being as nearly true as is possible with color illustrations of this type:

FIG. 1 shows the original seedling grown to a flowering tree;

FIG. 2 shows a close-up view of the fruits of the new variety at maturity;

FIG. 3 shows the leaves of the new variety; and

FIG. 4 shows the blossoms of the new variety.

 DESCRIPTION OF THE PLANT

The following detailed description sets forth the characteristics of the new cultivar. The data which defines these characteristics were collected by asexual reproductions by budding and grafting on apple tree rootstocks, including mostly ‘M-9’ rootstock, first carried out in The Czech Republic in the spring of 2000. The new variety was grown in a field under natural conditions with fertilization in kg/ha/year of N 55, P 25, K 60, Ca 55, and Mg 5. The color readings were taken in natural daylight. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London.
