| dc.description.abstract | Rapeseed (Brassica napus L.) is used as edible vegetable oil and industrial oil. Quantitative trait loci (QTL) controlling seed weight, flowering time and oil content were identified using a double haploid (DH) population. This population has 147 lines derived from the F1 of the spring type rapeseed, Topas, and the semi-winter type rapeseed, Zhongyou821. A linkage map was constructed using 599 SRAP and 595 SNP markers, which covers a size of 2060.62 cM with an average resolution of 1.73 cM. Six QTL for three traits were detected using the data gathered from field trials in two years. Two QTL for seed weight were located on chromosome C03 (qSWC03) in 2015 and on chromosome A03 (qSWA03) in 2016, two major QTL for flowering time on chromosome A02 (qFTA02-1 and qFTA02-2/3) in two years, two QTL for oil content on chromosome C07 (qOILC07) in 2015 and chromosome C03 (qOILC03) in 2016, respectively. | en_US |
