| 摘 要： | 利用潘那利番茄（Solanum pennellii）‘LA0716’与栽培番茄（S. lycopersicum）‘1052’为亲本构建BC5S2渐渗群体，对番茄果实和植株性状相关QTL进行了遗传定位分析，检测到了5个与单果质量相关的QTL位点，其中2个为新发现的位点；检测到2个与可溶性固形物含量相关的QTL位点，其中1个为新发现的位点；此外新发现了3个与株高相关的QTL位点和1个与叶片大小相关的QTL位点。

| Abstract: | In this paper，an introgression line population BC5S2 derived from the wild species Solanum pennellii‘LA0716’and the cultivated species S. lycopersicum‘1052’were used to map the loci for fruit traits and plant morphology. The results showed that five QTLs were identified for fruit weight，two of which were novel. Two QTLs were identified for soluble solids content，one was the novel locus. What’s more，three QTLs for plant height and one QTL related to leaf size in the study were all novel loci. |
