Abstract

A new cultivar of Prunus avium, ‘SPC103’, characterized by its very late harvest season, its flowers that are self-fertile, its intermediate to high precocity of fruit bearing, its spreading growth habit with horizontal one year-old shoots, its fruit skin and flesh that is dark red-purple in color with juice that is high in sweetness, and its firm and moderately juicy fruit that is kidney to cordate in shape.

Description

Botanical classification: Prunus avium.

Variety denomination: ‘SPC103’.

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, ‘SPC103’. ‘SPC103’ 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 centre in Summerland, BC, Canada with the goal of developing a new cultivar of cherry tree that would extend the harvest season with fruit that was firm and well-sized with good stem pull retention and flowers that were self-fertile.

‘SPC103’ originated as a seedling that arose from seed planted from open pollination of ‘Sweetheart’ (not patented) in 1984. ‘SPC103’ (breeding ref. No. 13S-21-23) was selected as a single unique tree in 1991 from amongst the resulting seedlings.

Asexual propagation of the new cultivar was first accomplished by budding onto Prunus avium rootstock by the Inventor in Summerland, BC, Canada in 1997. 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 as grown in test plots in Summerland, BC, Canada. These attributes in combination distinguish ‘SPC103’ as a unique cultivar of cherry tree.

    • 1. ‘SPC103’ exhibits a very late harvest season; August 12th in Summerland, BC, Canada.
    • 2. ‘SPC103’ exhibits flowers that are self-fertile.
    • 3. ‘SPC103’ exhibits an intermediate to high precocity of fruit bearing.
    • 4. ‘SPC103’ exhibits a spreading growth habit with horizontal one year-old shoots.
    • 5. ‘SPC103’ exhibits fruit skin and flesh that is dark red-purple in color with juice that is high in sweetness.
    • 6. ‘SPC103’ exhibits firm fruit that is moderately juicy and kidney to cordate in shape.

‘Sweetheart’, the female parent, is similar to ‘SPC103’ in being self-fertile but differs from ‘SPC103’ in having a tree habit that is more upright, longer fruit stalks, in having round shaped fruit, higher fruit set, and a fruit harvest maturity date about 9 days earlier. ‘SPC103’ can be most closely compared to the cultivars ‘13S2009’ (U.S. Plant Pat. No. 20,551) and ‘13S2101’ (U.S. Plant Patent pending)*. ‘13S2009’ is similar to ‘SPC103’ in being self-fertile but differs from ‘SPC103’ in having longer fruit stalks, higher fruit set, and a fruit harvest maturity date that is about 2 days earlier. ‘13S2101’ is similar to ‘SPC103’ in having a late harvest day, however ‘13S2101’ differs most significantly in having fruit that is red in color and elongated cordate in shape.

* Examiner has permission to replace U.S. Plant Patent pending with an Application No. or Patent No. if applicable and delete this statement.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying colored photograph illustrates the overall appearance and distinct characteristics of the fruit of ‘SPC103’ on a 15 year-old tree as grown in a trial plot in Summerland, B.C., Canada.

The photograph in FIG. 1 provides a view of a cluster of fruit of ‘SPC103’. The colors in the photograph are as close as possible with the digital photography techniques available, the color values cited in the detailed botanical description accurately describe the colors of the cherry tree.

DETAILED BOTANICAL DESCRIPTION
