Abstract

A new cultivar of Prunus avium tree named ‘SPC411’ that is characterized by its fruit that is large and very firm with a desirable appearance, its fruit with a low level of natural splitting, its fruit with good storage potential in regular air MAP bag, and its flowers that are self-fertile.

Description

Botanical classification: Prunus avium.

Variety denomination: ‘SPC411’.

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, ‘SPC411’. ‘SPC411’ 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, 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 ‘SPC103’ (U.S. Plant Pat. No. 26,645) in 1997. The male parent is therefore unknown. The Inventor selected ‘SPC411’ as a single unique plant amongst the resulting seedlings in 2002.

Asexual propagation of the new cultivar was first accomplished by budding onto Mazzard rootstock (not patented) under the direction of the Inventor in Summerland, B.C., Canada in 2003. 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 ‘SPC411’ as a unique cultivar of cherry tree.

• 1. ‘SPC411’ exhibits fruit that is large and very firm with a desirable appearance.
• 2. ‘SPC411’ exhibits fruit with a low level of natural splitting.
• 3. ‘SPC411’ exhibits fruit with good storage potential in regular air MAP (Modified Atmosphere packaging) bag.
• 4. ‘SPC411’ exhibits flowers that are self-fertile.

The female parent, ‘SPC103’, differs from ‘SPC411’ in having a much later harvest time and fruits that are less firm. ‘SPC411’ can be most closely compared to the cultivars ‘Sweetheart’ (not patented) and ‘13S2009’ (U.S. Plant Pat. No. 20,551). ‘Sweetheart’ is similar to ‘SPC411’ in harvest timing. ‘Sweetheart’ differs from ‘SPC411’ in having fruits that are smaller in size, much less firm, and a higher rate of natural splitting. ‘13S2009’ is similar to ‘SPC411’ in having dark red cherries with excellent eating quality and self-fertile flowers. ‘13S2009’ differs from ‘SPC411’ in having a much later harvest time, an earlier blooming period, and larger fruit with a higher percentage of natural splitting.
