DescriptionBlack walnut is an introduced species in the United Kingdom (UK) and economically one of the more productive broadleaved species. Currently it is not widely planted in the UK as there is insufficient knowledge about the species among foresters and very little, if any, improved material is available. A research programme was initiated in 2001 to address both these issues. A range-wide seed collection from plus trees 20 US provenances and 10 European provenances and 2 European populations has been undertaken with a view to establishing two provenance/progeny trials. A collection of trees grafted from 63 individual plus trees has also been planted for assessment of form, vigour and disease resistance.
