Variety Description

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

Summary: 'SPC243' is a blush type, sweet cherry variety which matures later in the harvest season than any of the reference varieties. The fruit of 'SPC243' is smaller and has a lower average fruit weight than all reference varieties. 'SPC243' has an elongated kidney shaped fruit, whereas '13N0770' has cordate fruit, 'Rainier' is flat round and the fruit of 'Sumtare' is round. The fruit skin of 'SPC243' has a yellow ground colour with orange red overcolour and yellow fruit flesh, whereas 'Sumtare', another very late season variety, has mahogany skin and dark red purple flesh and the reference '13N0770' has white flesh.

Origin & Breeding History: 'SPC243' was the result of the open pollination of the variety 'Sumtare' (Sweetheart) which occurred at the Pacific Agriculture Research Centre, Agriculture and Agri-Food Canada, Summerland, B.C. in 1982. A seedling was selected in 1995 and designated 'SPC243'. Five propagations were made on Prunus avium rootstock and planted out in a trial block at the Summerland Research Centre in 1999. Evaluation of the selection began upon fruiting. The variety 'SPC243' was selected on the basis of maturity date, size of fruit, firmness, field splits, fruit taste, fruit shape, skin and flesh colour, fertility, lustre, productivity and precocity.

Tests & Trials: Trials for 'SPC243' were conducted at the Pacific Agriculture Research Centre, Agriculture and Agri-Food Canada, Summerland, British Columbia from 1999 to 2006. The candidate variety and three reference varieties were planted in close proximity in test blocks located in Field 4, 5 and 13. The trials consisted of 4 trees per variety, grafted onto 'Mazzard' rootstock. Measured observations were based on a minimum of 15 measurements.
