  • BCC, GRA, HOR, TRI, AE, F, and R refer to accessions from the Leibniz Institute of Plant Genetics and Crop Plant Research GenBank. USDA refers to accessions from the National Genetic Resources Program of the USDA (United States). CN is accession from Plant Genetic Resources Canada (PGR Canada) and JB are accessions from a private collection of F.R.B. Genome designations of Triticeae taxa follow those in ref. 26, and genomes and sectional classification in Hordeum are according to those in ref. 27. All accessions, except for tetraploid H. bulbosum GRA970, are diploids (2n = 14).
