Description

FIELD
A new and distinct variety of apple tree designated as ‘NY73’. The plant is botanically known as Malus x domestica.
BACKGROUND
Apples are an economically important crop both domestically and internationally. There is a growing need to develop new varieties of apple trees with improved characteristics to meet the changing needs and demands of the producer, processor, and consumer.
BRIEF SUMMARY
Disclosed is an improved variety of apple tree. In particular, a new and distinct variety of apple tree (Malus x domestica), which has been denominated as ‘NY73’. The new variety ‘NY73’ has early maturity, is crisp, juicy, and has good flavor, with a balance of sweetness, acidity, and aromatics. The fruit are firm, large size, and unique in appearance with a bright pink blush color and light green background color, and overall attractive appearance. The fruit have multiple market uses. The fruit can be used for fresh consumption, in cooking, are suited to u-pick, retail, and wholesale markets, and in processing as part of a blended product.
‘NY73’ was selected for its excellent appearance (with a unique pink blush), quality attributes (crispness, juiciness, flavor, firmness), large size, and overall horticultural performance and consistency.
Apple tree ‘NY73’ is a hybrid that originated from a planned controlled cross in 1997 in Geneva, N.Y. The seed parent (female parent) is Malus x domestica ‘Imperial Gala’ apple tree (unpatented). The pollen parent (male parent) is Malus x domestica ‘Honeycrisp’ apple tree (U.S. Plant Pat. No. 7,197).
The original cross, designated ‘733’, was made by applying pollen from a ‘Honeycrisp’ apple tree onto emasculated flowers of an ‘Imperial Gala’ apple tree in Geneva, N.Y. in 1997. Seedlings were planted on their own roots in an orchard in Geneva, N.Y. in 1998, after being stratified and grown in the greenhouse. One seedling, designated NY97733-73, was selected from a field population of 331 seedlings on the basis of excellent fruit quality, firm flesh, and unique and attractive fruits. Additional trees of seedling NY97733-73 were produced by clonal propagation starting in 2002 and in subsequent years in Geneva, N.Y. These additional trees were evaluated for fruit and tree characteristics, pest resistance, and trueness-to-type. NY97733-73 was later designated as ‘NY73’.
‘NY73’ was first asexually (clonally) propagated by chip budding onto apple tree rootstock ‘M.9’ (unpatented) in 2002 in a research nursery in Geneva, N.Y. Subsequent asexual reproduction of ‘NY73’ has been successful using traditional grafting and budding methods of propagation, demonstrating that the unique combination of traits of the asexually propagated trees is identical in all appearances to the original tree. Asexual reproduction of this new variety by grafting and budding onto rootstocks shows that the characteristics of asexually propagated trees are true-to-type and are established and transmitted through succeeding propagations.
Distinguishing Characteristics of ‘NY73’
Seed Parent: The seed parent Malus x domestica ‘Imperial Gala’ is a sport of ‘Gala’ (U.S. Plant Pat. No. 3,637). ‘Gala’ and its colored sports are known for their fruit quality, characterized by having fruit with a spicy, sweet flavor. Bi-color fruit have a mixture of both red blush and stripes and a green/yellow background color, and a firm and juicy fruit texture with mostly smooth skin. Occasional russeting of the stem cavity and lenticels may occur. When compared to ‘Imperial Gala’, ‘NY73’ has similar scion vigor and tree characteristics. ‘NY73’ has similar fruit quality characteristics to ‘Imperial Gala’ in its firm texture. However, ‘NY73’ produces fruit that have larger fruit size and a pink/red blush color compared to the red blush/stripe of ‘Imperial Gala’.
Pollen Parent: The pollen parent ‘Honeycrisp’ is an internationally grown and recognized variety. When compared to ‘NY73’, the pollen parent ‘Honeycrisp’ produces fruit that have similar large size, but have a globose shape compared to the globose-conical shape of ‘NY73’. ‘NY73’ has a pink/red blush over-color compared to the less colored, lighter-red ‘Honeycrisp’ fruit. ‘NY73’ has greater scion vigor compared to the weaker growth habit of ‘Honeycrisp’. The texture and juiciness of ‘NY73’ are similar to its ‘Honeycrisp’ parent.
‘NY73’ has earlier fruit maturity, larger fruit size, lighter surface color, and a milder flavor compared to the commercial variety ‘Empire’. ‘Empire’ was introduced in 1966 and is not patented. The commercial variety ‘New York 2’ (Ruby Frost, U.S. Plant Pat. No. 22,207) has more full red color, globose fruit shape, and later fruit maturity compared to ‘NY73’ having a taller globose-conical fruit shape and lighter skin coloring. ‘New York 2’ has more acidity. Both ‘New York 2’ and ‘NY73’ have resistance to flesh browning after the fruits are cut.

 DETAILED BOTANICAL DESCRIPTION
The following description sets forth the distinctive characteristics of apple tree ‘NY73’. The following description is based on the originally identified apple tree and asexually reproduced progeny grown in Geneva, N.Y., which is in USDA Plant Hardiness Zone 6A.
Referring more specifically to the details of the new and distinct apple tree variety ‘NY73’, unless otherwise stated, the following observations and characteristics have been taken since 1999 from a number of trees in different orchards to provide consistent descriptions.
