QTL Mapping and Diurnal Transcriptome Analysis Identify Candidate Genes Regulating Flowering Time.

Timely flowering is important for seed formation and maximization of rapeseed () yield. Here, we performed flowering-time quantitative trait loci (QTL) mapping using a double haploid (DH) population grown in three environments to study the genetic architecture. Brassica 60 K Illumina Infinium™ single nucleotide polymorphism (SNP) array and simple sequence repeat (SSR) markers were used for genotyping of the DH population, and a high-density genetic linkage map was constructed.
