“…The locations of several major genes and quantitative trait loci (QTLs) associated with powdery mildew resistance have now been identified in barley ( Friedt and Ordon, 2007 ). For example, major resistance genes have been mapped to chromosome 1H ( Mla, Mlat, Mlk, Mlnn, Mlra, MlGa , and Mlp ), 2H ( MlLa ), 4H ( Mlg) , 5H ( Mlj ), 6H ( Mlh ), and 7H ( mlt and Mlf ) ( Jensen and Jørgensen, 1975 ; Doll and Jensen, 1986 ; Hilbers et al, 1992 ; Görg et al, 1993 ; Jørgensen and Wolfe, 1994 ; Schönfeld et al, 1996 ; Wei et al, 1999 ).…”

The powdery mildew fungus, Blumeria graminis f. sp. hordei is a worldwide threat to barley (Hordeum vulgare L. ssp. vulgare) production. One way to control the disease is by the development and deployment of resistant cultivars. A genome-wide association study was performed in a Nordic spring barley panel consisting of 169 genotypes, to identify marker-trait associations significant for powdery mildew. Powdery mildew was scored during three years (2012–2014) in four different locations within the Nordic region. There were strong correlations between data from all locations and years. In total four QTLs were identified, one located on chromosome 4H in the same region as the previously identified mlo locus and three on chromosome 6H. Out of these three QTLs identified on chromosome 6H, two are in the same region as previously reported QTLs for powdery mildew resistance, whereas one QTL appears to be novel. The top NCBI BLASTn hit of the SNP markers within the novel QTL predicted the responsible gene to be the 26S proteasome regulatory subunit, RPN1, which is required for innate immunity and powdery mildew-induced cell death in Arabidopsis. The results from this study have revealed SNP marker candidates that can be exploited for use in marker-assisted selection and stacking of genes for powdery mildew resistance in barley.

“…These variants are distributed among eleven groups; Mlat, Mia, Mlk, Minn, Mira, MIGa, and Mlp on chromosome 5 (1H) (reviewed by JORGENSEN 1994), Mlg and mlo on chromosome 4 (4H) (GÔRG et al 1993;BÛSCHGES et al 1997), MlLa on chromosome 2 (2H) (GIESE et al 1993), and Mlh on chromosome 6 (6H) (JORGENSEN 1994). Thirty-two specificities at the Mia locus have been differentiated by their specific reaction to unique isolates of E. graminis (GIESE 1981;GIESE et al 1981;WISE andELUNGBOE 1983, 1985;reviewed by JORGENSEN 1994;KINTZIOS et al 1995).…”
