Abstract

Waterlogging is a major factor limiting barley grain yield worldwide. Climate change will likely increase this water stress in Northern Europe. Breeding for waterlogging tolerance (WLT), as for other abiotic stresses, is difficult, but identification of genetic markers linked to genes affecting WLT could facilitate the breeding process. To identify a suitable marker population, parents of 14 double-haploid (DH) barley populations were tested for segregation of biomass growth reduction in waterlogged soil. The most interesting was found in the offspring from crossing cv. Psaknon and breeding line (SLUdt1398 from this cross were phenotyped for the chlorophyll fluorescence parameter quantum yield (QY) of electron transport of PSII from leaves of hypoxia-stressed plants and further genotyped with 384-SNP Illumina GoldenGate Bead Array. Five quantitative trait loci (QTL) for QY, with a narrow sense heritability of 0.879 Mona4). Hence, 120 DH-lines derived
