UNLABELLED
Oilseed rape ( L.) is one of the most essential oil crops. Genetic improvement of seed yield (SY) is a major aim of breeding. Several studies have been reported on the genetic mechanisms of SY of Here, a genome-wide association study (GWAS) of SY was conducted using a panel of 403 natural accessions of , with more than five million high-quality single-nucleotide polymorphisms (SNPs). A total of 1773 significant SNPs were detected associated with SY, and 783 significant SNPs were co-located with previously reported QTLs. The lead SNPs chrA01__8920351 and chrA02__4555979 were jointly detected in Trial 2_2 and Trial 2_mean value, and in Trial 1_2 and Trial 1_mean value, respectively. Subsequently, two candidate genes of and were identified through combining transcriptome, candidate gene association analysis, and haplotype analysis. detected through lead SNP chrA09__5160639 was associated with SY of . Our results provide valuable information for studying the genetic control of seed yield in and valuable genes, haplotypes, and cultivars resources for the breeding of high seed yield cultivars.

油菜（L.）是最重要的油料作物之一。种子产量（SY）的遗传改良是育种的主要目标。关于油菜种子产量的遗传机制已有多项研究报道。在此，利用一组403份油菜自然种质材料进行了种子产量的全基因组关联研究（GWAS），这些材料具有超过500万个高质量单核苷酸多态性（SNP）。共检测到1773个与种子产量相关的显著SNP，其中783个显著SNP与先前报道的数量性状位点（QTL）共定位。主效SNP chrA01__8920351和chrA02__4555979分别在试验2_2和试验2平均值中，以及试验1_2和试验1平均值中被联合检测到。随后，通过整合转录组、候选基因关联分析和单倍型分析，鉴定出两个候选基因。通过主效SNP chrA09__5160639检测到的与油菜种子产量相关。我们的结果为研究油菜种子产量的遗传控制提供了有价值的信息，并为高种子产量品种的育种提供了有价值的基因、单倍型和品种资源。
