Plant genetic resources are stored and regenerated in > 1750 gene banks storing > 7,000,000 accessions. Since seeds are the primary storage units, research on seed longevity is of particular importance. Quantitative trait loci (QTL) analysis of 15 traits related to seed longevity and dormancy using 7584 high-quality SNPs recorded across 2 years and originated from five production years revealed a total of 46 additive QTLs. Exploration of the QTLs with epistatic effect resulted in the detection of 29 pairs of epistatic QTLs. To our information, this is only the second report of epistatic QTLs for seed longevity in bread wheat. We conclude that in addition to dense genetic maps, the epistatic interaction between loci should be considered to capture more variation which remained unnoticed in additive mapping.

植物遗传资源在超过 1750 个基因库中储存和再生，储存了超过 7,000,000 份材料。由于种子是主要的储存单位，因此对种子寿命的研究尤为重要。使用 2 年内记录的 7584 个高质量 SNPs 对 15 个与种子寿命和休眠相关的性状进行定量性状基因座 (QTL) 分析，这些 SNPs 源自 5 个生产年，共发现 46 个加性 QTL。对具有上位效应的QTLs的探索导致检测到29对上位性QTLs。据我们所知，这只是面包小麦种子寿命上位性 QTL 的第二份报告。我们得出结论，除了密集的遗传图谱外，还应考虑基因座之间的上位相互作用以捕获更多在加性图谱中未被注意到的变异。
