“…These values are comparable to other studies for seed alkaloids (Beyer et al 2015b ) and anthracnose resistance (Alkemade et al 2022b ). While no report is available for heritability of protein content in white lupin, a value of H 2 = 0.82 is reported in narrow-leaved lupin by Beyer et al ( 2015a ) which is higher compared to our study ( H 2 = 0.63). Based on the heritability values and the large variation identified for the three studied traits, the LUW panel provided a good basis for the identification of SNP markers for these traits.…”

“…Lupin seeds have been recognized as valuable for both human and animal diet. They are high in protein (30–40%) and dietary fiber (45–50%), low in fat (6%) and with virtually no starch (Beyer et al 2015a ). For protein content, significantly associated SNPs were identified for the first time in white lupin.…”

“…These new findings complement modern breeding programs that mainly focus yield stabilization, resistance to abiotic stresses, resistance to diseases (mainly to anthracnose) and late maturing (Abraham et al 2019 ). In addition, improvement in lupin grain quality is requested to meet the food industry needs (Beyer et al 2015a ).…”

White lupin (Lupinus albus L.) is a high-protein grain legume alternative to soybean in Central Europe, but its cultivation is risky due to the fungal disease anthracnose that can cause severe yield damage. In addition, management of seed alkaloids is critical for human nutrition and animal feed. We report on a white lupin collection of genebank accessions, advanced breeding lines and cultivars that was genotyped and phenotypically characterized for anthracnose resistance and seed alkaloids and protein levels. Using genotyping by sequencing (GBS), SeqSNP-targeted GBS, BiomarkX genotyping and Sanger sequencing, a genetic resource of genome-wide SNPs for white lupin was established. We determined anthracnose resistance in two years field trials at four locations with infection rows and measured seed alkaloids and protein levels by near-infrared spectroscopy (NIRS). Few white lupin breeding lines showed anthracnose resistance comparable or better than Celina and Frieda, currently the best commercial cultivars in Germany. NIRS estimates for seed alkaloids and protein levels revealed variation in the white lupin collection. Using genome-wide association studies (GWAS), we identified SNPs significantly associated with anthracnose resistance in the field representing known and new genomic regions. We confirmed the pauper locus and detected new SNP markers significantly associated with seed alkaloids. For the first time, we present loci associated with total grain protein content. Finally, we tested the potential of genomic prediction (GP) in predicting the phenotype of these three quantitative traits. Application of results and resources are discussed in the context of fostering breeding programs for white lupin.
