White lupin seed can be used for traditional and functional foods or as animal feed. This study aimed to support lupin breeders and production stakeholders by assessing the extent of genotypic, environmental, and genotype × environment (GE) interaction effects on seed contents of oil, tocopherols (TOC), and quinolizidine alkaloids (QA), grain yield, and seed weight of eight elite genotypes grown in two climatically contrasting Italian locations for two cropping years. On average, plants in the subcontinental climate site exhibited higher grain yield and seed size, about 8% lower oil content, and almost 85% higher QA content than those in the Mediterranean climate site. The range of genotype means was 2.97-5.14 t/ha for yield, 92-110 mg/g for oil, and 0.121-0.133 mg/g for TOC. TOC amount was largely unpredictable and featured large GE interactions that hinder its genetic improvement. Oil and alkaloid contents and seed size are more predictable and offer potential for selection.
白羽扇豆种子可用于传统食品和功能性食品，或用作动物饲料。本研究旨在通过评估基因型、环境以及基因型×环境（GE）互作对八个优良基因型的种子油含量、生育三烯酚（TOC）、喹嗪生物碱（QA）、籽粒产量和种子重量的影响程度，来支持羽扇豆育种者和生产利益相关者。这八个优良基因型在意大利两个气候差异较大的地点种植了两个种植年份。平均而言，与地中海气候地区的植株相比，在大陆性气候地区的植株籽粒产量和种子大小更高，油含量低约8%，QA含量高近85%。基因型均值范围为产量2.97 - 5.14吨/公顷、油含量92 - 110毫克/克、TOC含量0.121 - 0.133毫克/克。TOC含量在很大程度上不可预测，且具有较大的GE互作，这阻碍了其遗传改良。油和生物碱含量以及种子大小更具可预测性，具有选择潜力。
