Title:
‘Harry Black Gala cultivar’
United States Patent PP12842
Abstract:
A new and distinct variety of Gala apple tree originating as a limb mutation of the Malus sylvestris variety of Gala, ‘McKenzie’ cultivar (U.S. Plant Pat. No. 3,637). This new variety is unique from its parent and other Gala cultivars because the fruit ripens 5 weeks later than the parent and Gala cultivars. The new variety is firmer than other Gala cultivars, averaging 18 to 23 pounds pressure at maturity.

A new and distinct variety of apple tree, Malus sylvestris, substantially as herein shown and described, characterized particularly as to novelty by the unique combination of a medium sized, vigorous, rounded tree with fruits that ripen 5 weeks later than other Gala cultivars and with substantially firmer fruits.

Description:

FIELD OF THE INVENTION

A new and distinct variety of apple tree originating as a limb mutation of the Malus sylvestris variety of Kidds D-8 Gala, ‘McKenzie’ cultivar, U.S. Plant Pat. No. 3,637, hereinafter referred to as the ‘Harry Black Gala’. Class: PLT. This new sport is unique from its parent because the fruit ripens 5 weeks later than its parent and is substantially firmer than the parent.

DESCRIPTION OF PRIOR ART

The new variety, ‘Harry Black Gala’, differs from its parent and other Gala varieties in the following characteristics:

A. The new variety ripens 5 weeks later than its parent, ‘McKenzie’ (U.S. Plant Pat. No. 3,637) and the following Gala cultivars: ‘Royal Gala’ (U.S. Plant Pat. No. 4,121), ‘Scarlet Gala’ (U.S. Plant Pat. No. 6,172), ‘Galaxy’ (U.S. Plant Pat. No. 6,955), ‘Treco Spur Gala No. 42’ (U.S. Plant Pat. No. 7,396), ‘Fulford’ (U.S. Plant Pat. No. 7,589), ‘Obragala’ (U.S. Plant Pat. No. 8,621), ‘Waliser’ (U.S. Plant Pat. No. 8,673), ‘Applewaites’ (U.S. Plant Pat. No. 8,720), ‘Baigent’ (U.S. Plant Pat. No. 10,016), ‘Gale’ (U.S. Plant Pat. No. 10,114), ‘Big Red Gala’ (U.S. Plant Pat. No. 10,458), and ‘Simmons’ (U.S. Plant Pat. No. 10,840). The new variety ripens 6 weeks later than ‘Olsentwo Gala’ (U.S. Plant Pat. No. 9,681).

B. The fruit of the new variety is firmer than its parent at commercial maturity. The new variety pressure tests at 18 to 23 pounds at commercial maturity while its parent averages 15 to 17 pounds at commercial maturity.

SUMMARY OF THE INVENTION

This new and distinct variety of Gala apple tree was discovered in 1993 as a limb mutation of ‘McKenzie’ cultivar, U.S. Plant Pat. No. 3,637, in an orchard planted in 1984 in Thurmont, Md. The new variety was noticed because the fruit ripens 5 weeks later than the parent and is much firmer than the parent. Observations during the next several seasons confirmed the late ripening and firmness. In October of 1994, buds were taken from the original tree and trees for further testing were asexually produced on M9-337 and EMLA 26 rootstocks and remains true to the description herein contained. It has not been reproduced on its own root.

A BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying photographs show typical specimens of the new variety as depicted in color as nearly true as is reasonably possible in color illustrations of this character. These specimens were obtained in Van Buren County, Mich.
