USPP27927P2 - Sweet cherry tree named ‘SPC243’ - Google Patents

Abstract

A new cultivar of sweet cherry tree named ‘SPC243’, that is characterized by its upright growth habit with semi-erect one year-old shoots and sparse crown density, its small fruit that is elongated kidney shaped, its fruit skin that is yellow in color with an orange-red over-color, its fruit flesh that is yellow in color, its moderate to high fruiting precocity, its flowers that are self-fertile, and its late to very late fruit harvest season.

Description

Botanical classification: Prunus avium.

Variety denomination: ‘SPC243’.

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, ‘SPC243’. ‘SPC243’ 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 extend the harvest season with firm, well-sized fruit with good stem pull retention, long storage life, and flowers that are self-fertile.

‘SPC243’ originated as a seedling that arose from seed planted from open pollination of ‘Sumtare’ (not patented). ‘SPC243’ was selected as a single unique tree in 1995 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 1999. 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 ‘SPC243’ as a unique cultivar of cherry tree.

• • 1. ‘SPC243’ exhibits an upright growth habit with semi-erect one year-old shoots and sparse crown density.
  • 2. ‘SPC243’ exhibits medium fruit that is elongated kidney shaped.
  • 3. ‘SPC243’ exhibits fruit skin that is yellow in color with an orange-red over color (blush cherry).
  • 4. ‘SPC243’ exhibits fruit flesh that is yellow in color.
  • 5. ‘SPC243’ exhibits a moderate to high fruiting precocity.
  • 6. ‘SPC243’ exhibits flowers that are self-fertile.
  • 7. ‘SPC243’ exhibits a late to very late fruit harvest season.

‘Sumtare’, the female parent of ‘SPC243’, is similar to ‘SPC243’ in being self-fertile. ‘Sumtare’ differs from ‘SPC243’ in having fruit that is round in shape, in having fruit skin that is mahogany in color, in having fruit flesh that is red-purple in color, in having fruit that is larger in size and heavier in weight, and in having fruit that matures earlier. ‘SPC243’ can be most closely compared to the sweet cherry cultivars ‘13N0770’ (not patented) and ‘Rainier’ (not patented). ‘13N0770’ is similar to ‘SPC243’ in being a blush cherry and in being self-fertile. ‘13N0770’ differs from ‘SPC243’ in having fruit that is flattened cordate in shape, in having fruit flesh that is white in color, in having fruit that is larger in size and heavier in weight, and in having fruit that matures over a week earlier. ‘Rainier’ is similar to ‘SPC243’ in being a blush cherry. ‘Rainier’ differs from ‘SPC243’ in having fruit that is flat and round in shape, in not being self-fertile, in having fruit that is larger in size and heavier in weight, and in having fruit that matures up to three weeks earlier.
