Abstract

A new and distinct Malus Mill. plant that produces crisp, juicy apples having a harmonious sugar-acid balance and excellent keeping quality, suitable for use as a dessert fruit.

Description

Botanical classification: Malus Mill.
Varietal denomination: ‘Sirius’.
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 ‘Sirius’. The new variety was discovered in 1999 in The Czech Republic. The new variety is the result of a cross between ‘Golden Delicious’ (female parent, unpatented) and ‘Topaz’ (male parent, unpatented). The purpose of the breeding program was to develop late disease resistant varieties of a high fruit quality that are also suitable for organic fruit production. The new variety exhibits similar ground fruit color, the absence of fruit overcolor, and the presence of fine russet around the stem cavity to ‘Golden Delicious’. Further, the new variety exhibits the trait of Vf-resistance against scab to ‘Topaz’, but exhibits triploidy, a stronger tree vigor, and very low pollen fertility compared to both parents. Further, the new variety differs from ‘Golden Delicious’ in its long storage capacity of fruits of common storage and the presence of Vf-resistance against scab. The new variety's globose to globose conical fruit form differs from the flat globose form of ‘Topaz’. Further, ‘Sirius’ exhibits a yellow fruit color versus the yellow-red color of ‘Topaz’. The following characteristics also distinguish the new variety from other Malus Mill. varieties known to the breeders:
    • Late, dessert-type, triploid variety with good keeping quality;
    • Trees exhibit strong vigor with a spreading habit;
    • Low pollen fertility;
    • Globose and slightly conical fruits;
    • Medium to long fruit stem;
    • Fine russeting around the stem cavity;
    • Yellow ground color of the fruit skin, with a mostly absent overcolor;
    • Flesh is firm, crispy and very juicy with a harmonic sugar/acid content and rich flavor;
    • Fruits do not drop when ripe; and
    • Vf-resistance against scab.
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 asexual propagations.
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. It should be noted that colors may vary with growing conditions and time of year:
FIG. 1 is a photograph of the tree of the new variety, showing canopy form and uniformly sized fruits at maturity;
FIG. 2 shows a close-up view of the fruits of the new variety at maturity;
FIG. 3 shows the blossoms of the new variety;
FIG. 4 shows the growing shoot of the new variety; and
FIG. 5 shows a close-up view of the young and mature leaves 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 was collected by asexual reproductions by budding and grafting on apple tree rootstocks first carried out in The Czech Republic. The new variety was grown under natural field conditions. The following fertilizer combination was used (Kg/ha/year): 55 parts nitrogen, 25 parts phosphorous, 60 parts potassium, 55 parts calcium, and 5 parts magnesium. Color references are primarily to the R.H.S Colour Chart of The Royal Horticultural Society of London.
