USPP28075P2 - Malus tree named ‘SPA493’ - Google Patents

Abstract

A new cultivar of apple tree, ‘SPA493’, that is characterized by its spreading tree habit that is easy to manage, its moderate growth rate, its medium sized fruit that is globose in shape, its fruit with a sweet-tart flavor, its fruit with skin that is yellow in color heavily blushed with red, its fruit that has a very long storage period, and its mid to late harvest period in British Columbia, Canada.

Description

Botanical classification: Malus domestica.

Varietal denomination: ‘SPA493’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of apple tree, botanically known as Malus domestica ‘SPA493’, referred to hereafter by its cultivar name, ‘SPA493’.

The new cultivar arose from a cross made by the Inventor in Summerland, British Columbia, Canada 1981 between ‘Splendour’ (U.S. Plant Pat. No. 2,460) as the female parent and ‘Gala’ (U.S. Plant Pat. No. 3,637) as the male parent. The Inventor selected ‘SPA493’ as a single unique plant amongst the seedlings that resulted from the above cross in 1997.

Asexual propagation of the new cultivar was first accomplished by vegetative budding onto ‘M26’ apple tree rootstock in 1997 under the direction of the Inventor in Summerland, BC, Canada. Asexual propagation by vegetative budding and grafting has determined that the characteristics of the new cultivar are stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new cultivar. These attributes in combination distinguish ‘SPA493’ as a unique cultivar of apple tree.

• • 1. ‘SPA493’ exhibits a spreading tree habit that is easy to manage.
  • 2. ‘SPA493’ exhibits medium sized fruit that is globose in shape.
  • 3. ‘SPA493’ exhibits fruit with a sweet-tart flavor.
  • 4. ‘SPA493’ exhibits fruit with skin that is yellow in color heavily blushed with red.
  • 5. ‘SPA493’ exhibits fruit that has a very long storage period.
  • 6. ‘SPA493’ exhibits a moderate growth rate.
  • 7. ‘SPA493’ exhibits a mid to late harvest period in British Columbia, Canada.

The female parent of ‘SPA493’, ‘Splendour’, differs from ‘SPA493’ in having fruit that is larger in size, ovoid-conical in shape, and green-yellow color, and in having an earlier harvest date. The male parent of ‘SPA493’, ‘Gala’, is similar to ‘SPA493’ in having fruit that is bicolored and medium in size, and in having a moderate growth rate. ‘Gala’, differs from ‘SPA493’ in having fruit that is conical in shape, in having fruit with moderate storability, and in having a more difficult to manage plant habit. ‘SPA493’ can also be compared to the apple tree cultivars ‘Ambrosia’ (U.S. Plant Pat. No. 10,789), ‘Royal Gala’ (U.S. Plant Pat. No. 4,121), and ‘BC2’ (unpatented). All three reference varieties differ from ‘SPA493’ in having fruit that is larger in size, in having leaves that are smaller in size, in having a later flowering habit, and in having shorter and thicker peduncles. ‘Ambrosia’ differs from ‘SPA493’ in having fruit that is globose-conical in shape and creamy-white in color, in having fruit with moderate storability and a very sweet flavor, and in having an earlier harvest date. ‘Royal Gala’ differs from ‘SPA493’ in having fruit that is globose-conical in shape and streaked and flecked red in color, and in having an earlier harvest date. ‘BC2’ differs from ‘SPA493’ in having fruit that is ellipsoid-conical in shape and green-yellow in color blushed red to dark red, and in having a later harvest date.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photograph illustrates the overall appearance and distinct characteristics of the new apple tree. The photograph was taken of fruit of a 7 year-old plant of ‘SPA493’ as grown outdoors in the ground on ‘M26’ apple rootstalk in Summerland, BC, Canada.

The photograph in FIG. 1 provides a close-up view of a line of trees of ‘SPA493’.

The photograph in FIG. 2 provides a close-up view of a flower and flower buds of ‘SPA493’.

The photograph in FIG. 3 provides a close-up view of the fruit of ‘SPA493’.

The colors in the photograph are as close as possible with the photographic and printing technology utilized and the color values cited in the detailed botanical description accurately describe the colors of the new apple tree.
