The South Lakeland Orchard Group - DNA Testing
Progress in Apple & Pear Cultivar Identification and Validation by DNA Analysis
by Andy Gilchrist, Chairman, South Lakeland Orchard Group
​
Gardeners who purchase an apple tree from a garden centre or nursery assume its labelled identity to be accurate. We all prefer certainty to uncertainty and expect things like cultivar identity to be black and white. Historically, it was difficult and time-consuming to prove otherwise. Consequently most mistaken identities went unnoticed and if the tree was subsequently used for propagation, the mistake endured, for decades or even centuries. Such mislabelling may occur during propagation either by carelessness or negligence. Labels over time become brittle and break off. In years gone by, an identity may have been forgotten, so a new name was given, leading to one or more synonyms for the same cultivar.
​
Fortunately in August 2010 the complete genome of Malus domestica was published, showing a structure of 17 pairs of chromosomes bearing 57,386 genes. East Malling Research then undertook a DNA analysis study ..... to read Andy's full LHS DNA article click here

Local Apples & Pears unique by DNA analysis named by the South Lakeland Orchard Group
DNA Analysis: fruitID have confirmed that the analysis program will run again this year (apples, pears & cherries), with the analyses to be done at Cambridge instead of East Malling. The price is £39 per sample. Leaf samples have to be taken during May/June. Please advise me if you have trees which you want identifying by DNA. Let me know by end April how many trees you want to sample and I will collate all SLOG requests to fruitID and then send you numbered bags in early May. Last years results can be viewed at fruitID | Apple Identification | Apple Varieties | Apple Cultivars. Halfway down the page you can click on “Apples 2022” or “Pears 2022”. To view the Register of Local Cultivars, click on the link near the top on the left.

ORIGINS:
Many of the pears were found by Phil Rainford at Crook Foot orchard settled in the Gilpin Valley, at the Western end of Crook village in Cumbria. They were propagated under the CR prefix.
