Data for Spring Barley from Nordic Seed A/S

A total of 2,628 plots of 565 spring malting barley lines from Nordic Seed A/S were investigated. Phenotypic records were available for six malting quality traits: filtering speed, wort clearness, extract yield, wort color, beta glucan, and wort viscosity. Each line had 3,889 dense genomic markers. In addition, 24,018 metabolomic features (MFs) were obtained for each sample from nuclear magnetic resonance spectra for wort samples produced from each experimental plot. Around one third of all MFs were significantly heritable, among which a considerable proportion had significant additive genetic and/or phenotypic correlations with the malting quality traits (wort color, wort viscosity and beta glucan) in spring barley. The results from this study indicate that many of the MFs are heritable and MFs have great potential to be used in breeding barley for high malting quality. These datasets include genotypic data for each line, phenotypic data for malting quality traits and metabolomic data for each plot.本研究共对来自北欧种子公司（Nordic Seed A/S）的565份春季麦芽大麦品系的2628个试验小区进行了调查。针对6项麦芽品质性状获取了表型数据，具体包括过滤速度、麦汁澄清度、浸出物得率、麦汁色泽、β-葡聚糖（beta glucan）以及麦汁黏度。每份品系均包含3889个高密度基因组标记。此外，通过对各试验小区制备的麦汁样品进行核磁共振波谱分析，为每个样品获得了24018个代谢组学特征（metabolomic features, MFs）。其中约三分之一的MFs具有显著遗传力，且此类特征中有相当比例与春季大麦的麦芽品质性状——麦汁色泽、麦汁黏度及β-葡聚糖存在显著的加性遗传相关和/或表型相关。本研究结果表明，多数MFs具备可遗传性，且这类代谢组学特征在高品质麦芽大麦育种中具有巨大应用潜力。本数据集包含各品系的基因型数据、麦芽品质性状的表型数据以及各试验小区的代谢组学数据。
