Variety Description

Varieties used for comparison: 'Burlat', 'Santina' and 'Sumnue'

Summary: 'Rivedel' is a non-self fertile, sweet cherry variety which has an elliptical leaf blade shape while 'Santina' has an elongated leaf blade and 'Sumnue' has a broad obovate leaf blade. 'Rivedel' has a longer leaf blade than 'Sumnue'. 'Rivedel' has deep, biserrate leaf margins while 'Burlat' has deep serrate margins, 'Santina' has medium depth bicrenate margins and 'Sumnue' has shallow bicrenate margins. 'Rivedel' has a shorter petiole length than 'Burlat' and longer petiole than 'Sumnue'. 'Rivedel' has a longer pedicel length than 'Burlat' and 'Santina'. 'Rivedel' has a larger fruit size than 'Burlat'. 'Rivedel' has kidney shaped fruit while 'Burlat' has flat round fruit and 'Sumnue' has slightly compressed kidney shaped fruit. The profile of the fruit in lateral view is flattened for 'Rivedel', rounded for 'Burlat', and obovate for 'Santina' and 'Sumnue'. 'Rivedel' has wine red coloured fruit skin while the reference varieties have mahogany to black fruit skin. 'Rivedel' has a less prominent suture than 'Burlat' and 'Sumnue'. The fruit juice is red for 'Rivedel' and dark red - purple for the reference varieties. 'Rivedel' has lower fruit acidity and is more susceptible to rain induced cracking of the skin than the reference varieties. 'Rivedel' has a longer fruit stalk than 'Burlat' and 'Santina' and a thinner stalk that the reference varieties.

Origin & Breeding History: 'Rivedel' was discovered as a chance seedling by the breeder, Paul Argot, in France in 1981. The applicant obtained this variety from the breeder in 1988 and made observations on it up to 1993 in Malicorne, France. Criteria used to select this variety were flowering date, harvest date, fruit colour, fruit size, fruit firmness and yield.

Tests & Trials: Trials for 'Rivedel' were conducted at the Pacific Agriculture Research Centre, Agriculture and Agri-Food Canada, Summerland, British Columbia, from 2004 to 2006. The candidate variety and three reference varieties were planted in close proximity in test blocks located in fields 4, 10 and 13. The trials consisted of 4 trees per variety, grafted onto 'Mazzard' rootstock. Measured observations were based on a minimum of 10 measurements.
