Integrating QTL mapping and GWAS to decipher the genetic mechanisms behind the calcium contents of <i>Brassica napus</i> shoots.

ABSTRACT: Brassica napus is an important oil crop worldwide, and its shoots are rich in vitamin C, calcium, and selenium. Functional oilseed-vegetable-dual-purpose varieties can increase the subsidiary value of B. napus. Consumption of high-calcium B. napus shoots can effectively help provide essential elements to the human body. To investigate the genetic mechanisms underlying the calcium concentrations of B. napus shoots, quantitative trait loci (QTL) mapping, using a population of 189 recombinant inbred lines, and a genome-wide association study, using an association panel of 202 diverse accessions, were performed. A total of 12 QTLs controlling calcium content were identified using the recombinant inbred line population in five environments. Among them, qCaC.22GY-A
