plant named ‘SPA766’

Abstract

A new cultivar of apple tree, ‘SPA766’, that is characterized by its fruit with skin that has a red over color with prominent medium sized lenticels, its fruit that is crisp with a pleasant tasting, its fruit that has a medium storage period, and its weak vigor.

Description

Botanical classification: Malus domestica.

Varietal denomination: ‘SPA766’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of apple tree, botanically known as Malus domestica ‘SPA766’, referred to hereafter by its cultivar name, ‘SPA766’.

The new cultivar arose from a cross made by the Inventor in Summerland, British Columbia, Canada in 1992 between an unnamed, proprietary plant in the Inventor's breeding program, reference no. 11W-16-016 as the female parent and Malus domestica ‘Chinook’ (U.S. Plant Pat. No. 10,669) as the male parent. The Inventor selected ‘SPA766’ as a single unique plant amongst the seedlings that resulted from the above cross in 1999.

Asexual propagation of the new cultivar was first accomplished by vegetative budding in 2000 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 ‘SPA766’ as a unique cultivar of apple tree.

• • 1. ‘SPA766’ exhibits fruit with skin that has a red over color with prominent medium sized lenticels.
  • 2. ‘SPA766’ exhibits fruit that is crisp with a pleasant taste.
  • 3. ‘SPA766’ exhibits fruit that has a medium storage period.
  • 4. ‘SPA766’ exhibits weak vigor.

The female parent of ‘SPA766’, reference no. 11W-16-016, differs from ‘SPA766’ in having fruit lenticels that are less pronounced and in having fruit that has a lighter red over color. The male parent, ‘Chinook’, is similar to ‘SPA766’ in having red fruit that is firm, crisp and pleasant tasting. ‘Chinook’ differs from ‘SPA766’ in having fruit that is smaller in size and different in shape. ‘SPA766’ can also be compared to the cultivar ‘Royal Gala’ (U.S. Plant Pat. No. 4,121). ‘Royal Gala’ is similar to ‘SPA766’ in having red fruit that is similar in shape. ‘Royal Gala’ differs from ‘SPA766’ in having fruit that is lighter red in color, in having less percentage of over color on the fruit and in having lenticels that are less prominent.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying colored photograph illustrates the overall appearance and distinct characteristics of the new apple tree. The photograph was taken of fruit on a 10 year-old plant of ‘SPA766’ as grown outdoors in the ground in Summerland, BC, Canada.

The photograph in FIG. 1 provides a close-up view of the fruit and foliage of ‘SPA766’.

The colors in the photographs 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.
