QTL analysis of seed oil content and gene markers in the QTL region in the DH population.

aQTL related to seed oil content were named according to trials and corresponding linkage group number; e.g., OW-A2 indicates QTL located in linkage group A2 in Wuhan trial (2010), OY-A3 indicates QTL located in linkage group A3 in Yangluo trial (2011), OQ-A6 indicates QTL located in linkage group A6 in Qinghai trial (2011).bNumber of linked markers ≤1 cM away from highest peak of QTL.cNumber of linked markers ≤5 cM away from highest peak of QTL.dLOD value associated with detected QTL.eAmount of phenotypic variation in total seed oil content (%) explained by a QTL.fADD additive effect (%) associated with detected QTL.gPositive additive effect showing that zy036 alleles increased seed oil content expression compared with 51070 alleles at associated QTL.hNegative additive effect showing that 51070 alleles increased seed oil content expression compared with zy036 alleles at associated QTL.iNewly developed marker related to oil-content genes.
