Grain protein content (GPC) in wheat has been found to be regulated by the gene NAM-B1. Homologues to the NAM-B1 gene have been found in barley, HvNAM-1 and HvNAM-2. Previous studies have found that base mutations in the NAM-1 gene at base position 544 might have an impact on GPC. Previous studies also found that landrace of barley showed higher GPC than cultivated barley, indicating that plant improvement might have affected base mutations and therefore GPC. I wanted to study if there are any nutritional differences in Nordic barley and if those differences might correlate with haplotypes. Comparisons of barley varieties from four Nordic countries, and two varieties from the US used as low and high GPC controls, did not show any significant differences depending on their origin country and no differences regarding plant improvement status between the countries. When sequencing Nordic barley varieties, five haplotypes were found for the gene HvNAM-1, and two haplotypes for the gene HvNAM-2. A low polymorphism for both genes indicate a strong natural selection for the consensus haplotype which might be preferable for Nordic climate with a short growing season and cold temperatures. Even though it is not clear what is the cause of the low polymorphism in Nordic barley varieties, they showed a generally higher nutrient content than barley varieties of the high GPC and may be suitable for breeding for a yield with a high nutrient content.
