摘要/Abstract

摘要：

以花椰菜等甘蓝类作物为研究对象，针对其显球期性状进行了遗传定位分析。通过构建两个F₂遗传分离群体，利用高密度遗传图谱为基础的QTL定位方法，成功在C8染色体末端共定位到控制花椰菜显球期性状的主效位点qDCA.C8-1（42 879 327 ~ 45 563 059 bp）。此外，还构建了以qDCA.C8-1为前景位点的F_2:3次级分离群体，利用极端混池测序（BSA）技术，再次重复定位到目标位点，进一步验证了qDCA.C8-1位点与花椰菜显球期性状的连锁关系。该位点在不同遗传群体中均表现出显著的遗传效应，且通过KASP标记验证了其可靠性。

Abstract:

This study focused on Brassica oleracea crops，particularly cauliflower，and performed genetic mapping analysis of the curd appearance trait. By constructing two F₂ genetic segregating populations and utilizing a QTL mapping approach based on high-density genetic maps，a major locus（qDCA.C8-1）controlling cauliflower curd appearance was successfully mapped on chromosome 8. Subsequently，an F_2:3 sub-segregating population targeting the qDCA.C8-1 foreground locus was developed. Using bulked segregant analysis（BSA）sequencing technology，the target locus was re-mapped，further confirming its linkage with the curd appearance trait. The qDCA.C8-1 locus demonstrated consistent and significant genetic effects across different genetic populations，and its reliability was verified through KASP markers.

Key words: cauliflower, curd appearance, two genetic populations, gene mapping
