油菜是世界上第二大油料作物。提高种子产量和种子含油量是本研究的两个主要亮点。不幸的是，油菜籽的发育经常受到不同疾病的影响。多年来，人们进行了广泛的研究，以开发具有高油、高产和/或抗病性的优良品种。数量性状基因座（QTL）分析已成为揭示农艺性状遗传规律的重要手段之一。为了了解这些QTL的分布情况，并揭示同时控制多个性状的关键区域，将过去25年中鉴定的4，555个QTL在一张独特的图谱上进行了比对，构建了一张涉及12个国家79个群体128个性状的定量基因组图谱。本研究共发现517个QTL重叠区域，包含2,744个候选基因，可能同时影响多个性状。可以通过选择来定制超级油菜品种。这些候选基因的基因本体和相互作用网络揭示了与其他基因高度相互作用的基因，并可能对它们产生强烈的影响。对这些候选基因在8份油菜材料中的表达和结构进行了比较，揭示了结构相似但表达不同的基因。本研究丰富了油菜基因组特征和多样性的认识，也为今后油菜分子育种改良提供了参考。
Rapeseed is the second most important oil crop in the world. Improving seed yield and seed oil content are the two main highlights of the research. Unfortunately, rapeseed development is frequently affected by different diseases. Extensive research has been made through many years to develop elite cultivars with high oil, high yield, and/or disease resistance. Quantitative trait locus (QTL) analysis has been one of the most important strategies in the genetic deciphering of agronomic characteristics. To comprehend the distribution of these QTLs and to uncover the key regions that could simultaneously control multiple traits, 4,555 QTLs that have been identified during the last 25 years were aligned in one unique map, and a quantitative genomic map which involved 128 traits from 79 populations developed in 12 countries was constructed. The present study revealed 517 regions of overlapping QTLs which harbored 2,744 candidate genes and might affect multiple traits, simultaneously. They could be selected to customize super-rapeseed cultivars. The gene ontology and the interaction network of those candidates revealed genes that highly interacted with the other genes and might have a strong influence on them. The expression and structure of these candidate genes were compared in eight rapeseed accessions and revealed genes of similar structures which were expressed differently. The present study enriches our knowledge of rapeseed genome characteristics and diversity, and it also provided indications for rapeseed molecular breeding improvement in the future.
