Variety Description

Varieties used for comparison: '13N0770' (Stardust) and 'Rainier'

Summary: 'SPC207' is a self fertile, blush, sweet cherry variety with more vigourous trees than either '13N0770' or 'Rainier'. 'SPC207' has longer leaves with deeper margin indentations than the reference varieties. 'SPC207' has larger flowers and significantly larger fruit and larger stone than '13N0770' and 'Rainier'. The fruit of 'SPC207' is a flattenend heart, whereas '13N0770' has a cordate fruit shape and 'Rainier' is flat round. 'SPC207' matures a few days earlier than '13N0770' but several days after 'Rainier'.

Origin & Breeding History: 'SPC207' was the result of the cross Stella x 2S-84-10, which was made at the Pacific Agriculture Research Centre, Agriculture and Agri-Food Canada, Summerland, B.C. in 1976. The parent 2S-84-10 was a Summerland breeding line which resulted from the open pollination of Stella 35A. The seedling cross was designated 'SPC207' in 1997. Two propagations were made on Prunus avium rootstock and planted out in a trial block at the Summerland Research Centre in 1985. Evaluation of the selection began upon fruiting. The variety 'SPC207' was selected on the basis of maturity date, size of fruit, firmness, field splits, fruit shape, skin and flesh colour, fertility, luster, productivity and precocity.

Tests & Trials: Trials for 'SPC207' were conducted at the Pacific Agriculture Research Centre, Agriculture and Agri-Food Canada, Summerland, British Columbia from 1999 to 2005. The candidate variety and two reference varieties were planted in close proximity in test blocks located in Field 4 and 13. The trials consisted of 4 trees per variety, grafted onto 'Mazzard' rootstock. Measured observations were based on a minimum of 15 measurements.
