Abstract [en]

Barley landraces from Northern Europe formgenetically distinct latitudinal groups, suggestingthat adaption plays an important role inthe geographical distribution of genetic diversity.Here, we investigate how Northern Europeanbarley landraces relate to landraces fromother parts of Europe and whether candidategenes for climate adaption can be identified.For this purpose, 27 barley landraces, availableas century-old seed specimens, were genotypedwith a 384 single nucleotide polymorphism(SNP) assay. Landraces from the Nordiccountries formed a genetically distinct grouprelative to landraces from Central and SouthernEurope. Polymorphic positions in the floweringtime genes HvCO1, HvFT1, Ppd-H1, and VRN1-H1 were genotyped. The previously known alleledistribution of Ppd-H1 with the responsive allelepresent in the South and the nonresponsiveallele in the North was confirmed. The otherthree genes were more variable in Central andSouthern Europe compared to the North andneither of the flowering time genes showedany geographically correlated variation withinthe Nordic countries. Allelic frequencies fromthe 384 SNP set were correlated with climaticvariables. This allowed us to identify five SNPsputatively associated with length of growth season,and two SNPs putatively associated withprecipitation. The results show how historicalcrop specimens can be used to study howgenetic variation has been geographically distributedand the genetics of adaption.
