许多重要的苹果（Malus × Domestica Borkh.）果实品质性状受多个基因调控，标记辅助选择需要更多有关这些性状数量性状基因座（QTL）的信息。在这项研究中，我们利用源自日本苹果品种‘Orin’和‘Akane’的杂交 F1 幼苗构建了这些品种的遗传连锁图谱。 “Orin”图谱由覆盖 17 个连锁群（LG；总长度 1095.3 cM）的 251 个基因座组成，“Akane”图谱由覆盖 18 个 LG 的 291 个基因座（总长度 1098.2 cM）组成。我们对16个重要性状进行了QTL分析，发现与收获时间相关的4个QTL解释了约70%的遗传变异，这将有助于标记辅助选择。 LG15 中早期收获期的 QTL 与采前落果的 QTL 非常接近。肤色深度QTL位于LG9中MYB1位置附近，表明‘Akane’所携带的等位基因对红色深度有不同程度的调节作用。我们还分析了可溶性固形物和糖成分含量，发现LG16中可溶性固形物含量的QTL可以用山梨醇和果糖的含量来解释。
Many important apple (Malus × domestica Borkh.) fruit quality traits are regulated by multiple genes, and more information about quantitative trait loci (QTLs) for these traits is required for marker-assisted selection. In this study, we constructed genetic linkage maps of the Japanese apple cultivars ‘Orin’ and ‘Akane’ using F1 seedlings derived from a cross between these cultivars. The ‘Orin’ map consisted of 251 loci covering 17 linkage groups (LGs; total length 1095.3 cM), and the ‘Akane’ map consisted of 291 loci covering 18 LGs (total length 1098.2 cM). We performed QTL analysis for 16 important traits, and found that four QTLs related to harvest time explained about 70% of genetic variation, and these will be useful for marker-assisted selection. The QTL for early harvest time in LG15 was located very close to the QTL for preharvest fruit drop. The QTL for skin color depth was located around the position of MYB1 in LG9, which suggested that alleles harbored by ‘Akane’ are regulating red color depth with different degrees of effect. We also analyzed soluble solids and sugar component contents, and found that a QTL for soluble solids content in LG16 could be explained by the amount of sorbitol and fructose.
