Interpretive Summary: Germplasm is the foundation for breeding new and improved barley varieties. Genomic selection is a new molecular technology for germplasm improvement and crop variety selection. Northern American barley researchers collaborated to characterize 233 barley breeding lines via field testing at 44 locations and assessment with 6000 DNA markers. Characterization data for these lines are available in a public database and will be useful for barley improvement and variety development in the future.

Technical Abstract: Changes in the malting and brewing industries have increased the demand for locally produced barley (Hordeum vulgare L.). Breeding for productive barley cultivars in many disparate growing environments is complicated by genotype-environment interactions (GEIs), which may be exploited to select optimal cultivars for each environment. Genomewide selection (GS) has recently become a useful tool, adopted in many breeding programs, to make efficient selections on individuals using genomewide marker data. In order to support the use of GS to breed locally-adapted barley cultivars, we are publicly releasing a panel of two-row barley individuals, and accompanying data, called the S2MET (Spring Two-Row Multi-Environment Trial). The S2MET includes 233 breeding lines, grouped into a 183-line training population (TP) and a 50-line validation population (VP), currently genotyped with 6361 single nucleotide polymorphism markers. The panel has been phenotyped in more than 44 location-year environments between 2015 and 2017, with robust data on 14 agronomic and malting quality traits. The panel is intended to serve as a collaborative dataset for testing hypotheses related to GS and GEIs and as a source of breeding material and data for making selections. As such, all data is available freely from the Triticeae Toolbox (https://triticeaetoolbox.org/barley/), and we describe several on-tap projects and breeding advances that are exploiting this resource. We believe this panel and dataset will prove invaluable for answering important breeding questions and efficiently developing locally superior barley cultivars.
