All QTLs were prefixed with “cq”, followed by the abbreviated trait name, mapped linkage group, and a small alphabet (a, b, ...) representing multiple QTLs if they are detected for the trait in the same linkage group and same environment. For example, cqOCA1a is one of the two QTLs for oil content (OC) detected on linkage A1, and cqOCA1b is another one.
CI: the flanking marker closest to the 95% confidence interval; R2: percentage of the phenotypic variation explained by the QTL.
Additive effects indicate the effects of “M201” allele.
Y11–rapeseed growth environment in 2011 at Hezhen, Gansu Province, China; Y12 and Y13–rapeseed growth environments in 2012 and 2013 at the experimental farm in Wuhan, Hubei Province, China.
QTL in Ref were the QTL detected in previous studies. The references for the QTL were also shown in the same column.
