The BBC is reporting that scientists have agreed on a system for DNA barcodes for plants. They see applications in monitoring the trade in CITES-protected plants and also in forensics.

I wonder if it might have applications in protecting against the illegal trade in PVR- or patent-protected plants, particularly if it was married with some sort of simple hand-held equipment which allowed people with limited training (perhaps customs officials) to sample consignments of plant material. But I also wonder how much information can be contained in the limited fragments of DNA that they are using (it might be good enough to identify plants at species level, but perhaps not good enough to identify individual varieties – Alstroemeria, for example, are notoriously similar in terms of DNA when varieties are compared) and also how long it will take to compile a comprehensive DNA database (the current Plant Finder lists over 75,000 varieties of plant available to purchase in the UK).

Both CIOPORA and the CPVO have been looking into the issue of DNA fingerprinting for protected plants – I believe that the CPVO is conducting a pilot project with the genus Rosa. Perhaps we will see more developments on this in the future.

One of the best events in the European horticultural calendar is coming round again – Plantarium.

Graham will be at Plantarium on Wednesday 26 and Thursday 27 August. If you want to arrange a meeting there, please contact us.

Tomorrow sees the annual Woking Nursery Exhibition. Although a modest sized event compared to some, this is an important event in the British horticulture calendar, noted for its relaxed environment and good range of British growers on display. Graham will be at the exhibition for most of the day, so please feel free to collar him if you see him about.

This year’s event sees the launch of two plants in the PFE portfolio. Geum Totally Tangerine (PVR applied for), bred by Tim Crowther, will be exhibited by Farplants. Meanwhile, New Place Nurseries will be showing Cistus corbariensis Little Miss Sunshine™ (PVR and trademark applied for), bred by well-known Irish plantsman, Kieran Dunne.

Be sure to look out for these excellent new plants. Contact us if you’d like to know more.
