DNA analysis of local varieties – our part in the national review – and an update

We have, as many will know, been taking part in a national initiative using DNA analysis to rationalise and better understand local varieties – how they relate (literally!) to one another and whether some are identical to others.  And, where they are identical to others with differing names (perhaps in other areas) which name should take precedent,

This has been a challenging project, requiring leaf samples from named varieties being sent to labs, particularly East Malling Research centre in Kent, for analysis.  The project is not ours – though several people from the GOT committee are involved and we are significant contributors of samples – it is a national initiative we are helping with.  Updates on progress overall can be found on the FruitID website’s help pages: https://www.fruitid.com/index.html#help – click on Register of LocalCultivars for documentation.

But where, after 3 years or so of work, have we got to in Gloucestershire?

Well, we do now have new and revised lists of Gloucestershire apple and pear varieties – some details of which rock the boat a little – we have fewer ‘Gloucestershire’ varieties than we thought!  But that’s to be expected when everything is compared using DNA – there are bound to be matches and competing claims.

The revised listings (as at the end of November 2019) are now available on the varieties part of our website – https://glosorchards.org/home/fruitvarieties/research/
(December 2019 update:  the documentation there has been revised since this posting – the original files available on the link have now been deleted and replaced by the updated ones)
