随着需要食用油的人口不断增加和使用生物燃料的工业的扩大，全世界的石油消费量正在增加。因此，对高产油料作物品种的需求一直在增加。甘蓝型油菜（Brassica napus，油菜籽）是世界上最重要的油料作物之一，为了满足畜牧业对植物油和优质蛋白质的高需求，通过育种提高油菜籽产量势在必行。数量性状基因座（QTL）分析是鉴定重要基因座的有力工具，在分子标记辅助育种中具有重要价值。种子产量（SY）是一个受多基因控制的复杂性状，直接受种子重、角果粒数和角果数的影响。一些与产量相关的性状，如株高、生物产量、开花时间等，也间接影响着SY。本研究将油菜种子产量及产量相关性状的QTL组装在一张独特的图谱上。将972个与种子产量及产量相关的QTL定位到B的物理图谱上。在16条染色体上共检测到92个QTL重叠区，其中198个QTL重叠区位于16条染色体上。在131个QTL重叠的65个区域中，共发现147个潜在候选基因，可能影响9个不同的性状。最后，对候选基因的互作网络进行了研究，发现了9个与其他基因互作程度较高，可能对其他基因产生较大影响的基因。本研究结果有助于开发与产量相关性状的分子标记，并可用于B的育种改良。油菜。
Worldwide consumption of oil is increasing with the growing population in need for edible oil and the expansion of industry using biofuels. Then, demand for high yielding varieties of oil crops is always increasing. Brassica napus (rapeseed) is one of the most important oil crop in the world, therefore, increasing rapeseed yield through breeding is inevitable in order to cater for the high demand of vegetable oil and high-quality protein for live stocks. Quantitative trait loci (QTL) analysis is a powerful tool to identify important loci and which is also valuable for molecular marker assisted breeding. Seed-yield (SY) is a complex trait that is controlled by multiple loci and is affected directly by seed weight, seeds per silique and silique number. Some yield-related traits, such as plant height, biomass yield, flowering time, and so on, also affect the SY indirectly. This study reports the assembly of QTLs identified for seed-yield and yield-related traits in rapeseed, in one unique map. A total of 972 QTLs for seed-yield and yield-related were aligned into the physical map of B. napus Darmor-bzh and 92 regions where 198 QTLs overlapped, could be discovered on 16 chromosomes. Also, 147 potential candidate genes were discovered in 65 regions where 131 QTLs overlapped, and might affect nine different traits. At the end, interaction network of candidate genes was studied, and showed nine genes that could highly interact with the other genes, and might have more influence on them. The present results would be helpful to develop molecular markers for yield associated traits and could be used for breeding improvement in B. napus.
