New wild spinach material collected in Armenia and Azerbaijan by CGN in 2011.

The newly available accessions of the spinach wild relative Spinacia tetrandra may provide new genetic resources that can be used in research and crop breeding.

For 16 accessions of S. tetrandra seed samples are now available for distribution. Nine accessions of S. oleracea originating from the same expedition were already made available earlier.

A wild Spinacia tetrandra accession collected in Georgia in 2001
