aOTGR, LTGR, LTPRL represents optimum-temperature germination rate, low-temperature germination rate, low-temperature primary root length, respectively.
bChromosome Bins of the marker and position taken from IBM 2008.
cLOD: Log10-likelihood value.
dAdditive effect: The negative value of additive effect indicates the allele from B73 is positive.
eR2: coefficient of determination, which represents the percentage of phenotypic variance explained by a putative QTL.
