USPP29788P2 - Sweet cherry tree named ‘SPC342’ - Google Patents

Abstract

A new cultivar of sweet cherry tree, ‘SPC342’, that is characterized by its very high fruit stem pull force, its large fruit with an attractive appearance, its flowers that are not self-fertile, its distinctive maroon spots on its leaves, and its good fruit storage capacity in MAP (modified atmosphere packaging).

Description

Botanical classification: Prunus avium.

Variety denomination: ‘SPC342’.

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, ‘SPC342’. ‘SPC342’ 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, BC, Canada with the goal of developing new cultivars of cherry tree that would have improvements to the fruit appearance, fruit taste, fruit flesh texture, tree quality, productivity and precocity.

‘SPC342’ originated as a seedling that arose from seed planted from open pollination of Prunus avium ‘Lapins’ (not patented). ‘SPC342’ was selected as a single unique tree in 2000 from amongst the resulting seedlings.

Asexual propagation of the new cultivar was first accomplished by chip budding and grafted onto Prunus avium rootstock by the Inventor in Summerland, BC, Canada in 2003. Asexual propagation by chip 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 ‘SPC342’ as a unique cultivar of cherry tree.

• • 1. ‘SPC342’ exhibits a very high fruit stem pull force.
  • 2. ‘SPC342’ exhibits large fruit with an attractive appearance.
  • 3. ‘SPC342’ exhibits flowers that are not self-fertile.
  • 4. ‘SPC342’ exhibits distinctive maroon spots on its leaves.
  • 5. ‘SPC342’ exhibits good fruit storage capacity in MAP (modified atmosphere packaging).

‘Lapins’, the female parent of ‘SPC342’, differs from ‘SPC342’ in having a later fruit maturity and in having smaller sized fruit. ‘SPC342’ can be most closely compared to the sweet cherry cultivars Prunus avium ‘Bing’ (not patented) and Prunus avium ‘Sumnue’ (not patented). ‘Bing’ is similar to ‘SPC342’ in fruit harvest timing. ‘Bing’ differs from ‘SPC342’ in having fruit that is smaller in size, in having a lower fruit stem pull force and in having different alleles. ‘Sumnue’ is similar to ‘SPC342’ in eating quality and in having cherries that are dark red in color. ‘Sumnue’ differs from ‘SPC342’ in having a slightly earlier fruit harvest date, in having fruit that is smaller in size, in having a lower fruit stem pull force and in having different alleles.

BRIEF DESCRIPTION OF THE DRAWINGS
