“…Today, this method, along with traditional linkage mapping with bi-parental populations, is routinely used for the identification of QTLs in crops, including barley. During the last decade alone, GWAS in barley has been successfully used for the identification of QTLs for abiotic stress tolerance [ 34 , 35 , 36 ], adaptation traits [ 37 , 38 , 39 ], yield-related traits [ 40 , 41 ], grain components and quality traits [ 42 , 43 , 44 ], and resistance to diseases [ 45 , 46 , 47 , 48 ]. Novel PM resistance QTLs have been identified using GWAS in wheat [ 49 , 50 ], oat [ 51 ], rye [ 52 ], and, of course, barley [ 53 , 54 , 55 , 56 ].…”
