Summary: Global climate change is causing increased rainfall in Northern Europe, leading to more field flooding and impacting crop yield. Researchers evaluated 403 winter barley cultivars for waterlogging tolerance and identified sensitive and tolerant cultivars. Variability in cultivar responses to waterlogging stress was observed in multi-season field trials, prompting the development of an enhanced phenotyping method to better assess cultivars' responses under controlled conditions.

Summary: This study evaluated the dynamic response and genetic basis of rapeseed waterlogging tolerance in the field using a high-throughput UAV phenotyping platform. The results showed that rapeseed had severe waterlogging response within 18 days after recovery, but it subsequently decreased partly. Genome-wide association studies identified 289 and 333 loci associated with waterlogging tolerance in 2 years. Highly reliable loci, which were defined based on at least nine associations with waterlogging-related traits, were identified.

Summary: Waterlogging is a growing threat to wheat production in high-rainfall areas. This study identified three quantitative trait loci (QTL) associated with waterlogging tolerance in wheat and developed markers for marker-assisted selection (MAS) to improve waterlogging tolerance. These findings are of great importance for enhancing waterlogging tolerance in wheat.

Summary: Waterlogging poses a threat to wheat production, but a wheat-sea wheatgrass amphiploid has been developed that exhibits strong tolerance to waterlogging and low nitrogen conditions. The study found that the amphiploid effectively adapts to waterlogging stress through enhanced nitrate assimilation and reduction, as well as accumulation of nitric oxide.

Summary: The importance of good drainage for improving crop yield and stability was highlighted in this study, where poor drainage conditions were found to potentially cause up to a 25% reduction in yield. The study also showed that factors other than nitrogen fertilization play a significant role in the reduction of yield potential due to poor field drainage.

Summary: The study identified allelic variation at two major loci, QSnb.nmbu-2A.1 and QSnb.nmbu-5A.1, with consistent and additive effects on SNB field resistance. Validation of QSnb.nmbu-2A.1 across genetic backgrounds further highlights its usefulness for marker-assisted selection. Combining resistance alleles at both loci resulted in additive effects on SNB resistance, indicating that marker-assisted selection is a promising strategy for improving SNB resistance in wheat breeding.

Summary: This study conducted a functional data analysis of weather-based time series data linked to DON content in Norwegian oats and identified weather patterns associated with increased DON levels. Oat fields with elevated DON levels generally had warmer weather around sowing, and lower temperatures and higher relative humidity or rain prior to flowering onwards, compared to fields with low DON levels. Functional data analysis was found to be a useful tool to reveal weather patterns of importance for DON development in oats.

Summary: Two loci on chromosomes 2BS and 6AL were found to significantly contribute to stripe rust resistance in current European winter wheat germplasm. These findings provide valuable information for the breeding programs aimed at developing rust resistant cultivars. Genomic association analysis identified 12 SNP markers on six wheat chromosomes that consistently showed effects on adult plant stripe rust resistance. Two highly predictive markers on chromosomes 2BS and 6AL were validated in three independent populations, indicating their potential for efficient selection of resistant cultivars.

Summary: A new QTL, QSnb.nmbu-2AS, for SNB resistance was discovered in both winter and spring wheat panels, which can significantly contribute to SNB resistance breeding. Genome-wide association studies identified 10 common QTL on 11 wheat chromosomes, and one QTL on chromosome 2A showed consistent and significant effects in both panels. However, the presence of resistant haplotypes in Nordic wheat cultivars is relatively low, indicating the potential of integrating this QTL in SNB resistance breeding programs. Furthermore, stacking resistant alleles of the detected QTL showed clear and significant additive effects, suggesting the potential application of marker-assisted selection in SNB resistance breeding.

Summary: Climate change and global food security efforts are increasing the demand for adaptable crops in higher latitude temperate regions. This study evaluated the freezing tolerance (FT) of 160 winter wheat genotypes and identified germplasm with high FT. Differences in FT were observed based on country of origin, release years, and culton type. FT measurements under controlled conditions were shown to correlate with overwintering survival scores in the field, validating its reliability as a high-throughput method for FT evaluation. Genome-wide association studies revealed SNP markers associated with FT, and candidate genes were identified for introduction into winter wheat breeding programs in the Nordic region.
