Cherry tree named ‘SPC495’

Abstract

A new cultivar of Prunus avium tree named ‘SPC495’ that is characterized by its very late fruit harvest, its flowers that are self-fertile, its large fruit with a desirable appearance, its fruit with a low level of natural splitting, and its good storage potential in regular air MAP bag.

Description

Botanical classification: Prunus avium.

Variety denomination: ‘SPC495’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Prunus avium and will be referred to hereafter by its cultivar name, ‘SPC495’. ‘SPC495’ is a new cultivar of sweet cherry tree grown for fruit production.

The new cultivar of Prunus arose from a breeding program conducted by the Inventor at a research center in Summerland, B.C., Canada with the goal of developing a new cultivar of cherry tree with improved fruit appearance, taste, firmness, flesh texture, productivity, precocity, harvest timing, and split resistance with improved tree quality and disease resistance.

The new cultivar arose from open pollination of ‘13S2009’ (U.S. Plant Pat. No. 20,551) in 2000. The male parent is therefore unknown. The Inventor selected ‘SPC495’ as a single unique plant amongst the resulting seedlings in 2009.

Asexual propagation of the new cultivar was first accomplished by budding onto Mazzard (not patented) rootstock under the direction of the Inventor in Summerland, B.C., Canada in 2009. Asexual propagation by budding 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 ‘SPC495’ as a unique cultivar of cherry tree.

• • 1. ‘SPC495’ exhibits a very late fruit harvest.
  • 2. ‘SPC495’ exhibits flowers that are self-fertile.
  • 3. ‘SPC495’ exhibits large fruit with a desirable appearance.
  • 4. ‘SPC495’ exhibits fruit with a low level of natural splitting.
  • 5. ‘SPC495’ exhibits good storage potential in regular air MAP (Modified Atmosphere packaging) bag.

The female parent, ‘13S2009’, is similar to ‘SPC495’ in having fruit with excellent eating attributes and dark red in color and flowers that are self-fertile. The female parent differs from ‘SPC495’ in having fruit that are larger in size, less firm, a higher rate of natural spitting, and an earlier harvest time, and a later blooming period. ‘SPC495’ can be most closely compared to the cultivar ‘Sweetheart’ (not patented). ‘Sweetheart’ is similar to ‘SPC495’ in being self-fertile and having fruit with low susceptibility to natural splitting. ‘Sweetheart’ differs from ‘SPC495’ in having fruits that are smaller in size with less natural splitting and a much earlier harvest period.
