Genome wide association studies (GWAS) were conducted to identify net blotch (net form: caused by Pyrenophora teres f. teres) resistance loci in Ethiopia and Eritrea (EEBC) barley landraces and the elite germplasm of the Barley Coordinated Agricultural Project (Barley CAP). Two quantitative trait loci (chromosomes 5H and 6H) were identified in the EEBC. Resistance QTL were found in chromosomes 4H and 6H in the two-row panel, chromosomes 3H and 6H in the six-row panel and in chromosomes 3H, 4H, 6H and at an unmapped location in the combined Barley CAP germplasm. The distribution of Barley yellow dwarf (BYD), caused by Barley/cereal yellow dwarf virus (B/CYDV) in the Luteovirus family, in Minnesota was studied using 243 cereals and grass samples collected from 2013 to 2015. Reverse transcription polymerase chain reaction using virus strain specific primers revealed that BYDV-PAV was the most prevalent strain of B/CYDV.
