European hazelnut (Corylus avellana L.) is of global agricultural and economic significance, with genetic diversity existing in hundreds of accessions.

Here we present the first sequenced genome in the order Fagales: the de novo assembled genome and transcriptome of the diploid hazelnut accession ‘Jefferson’ (OSU 703.007), along with the characterization of millions of polymorphisms discovered from the resequencing of seven additional hazelnut accessions.  In addition, we have added thousands of new genetic markers, derived using genotyping-by-sequencing (GBS), to the hazelnut linkage map.

These genomic resources will aid the discovery of genes of interest and the development of molecular markers for hazelnut breeding efforts.

We present these genomic tools to the global hazelnut community, available via the links below.
