aA peak in a marker interval along the LOD profile was treated as a QTL, if there is at least one environment with the peak value higher than the LOD threshold

bChromosomal position (cM) of the peak

cThe number in bold was the value of a peak higher than the threshold value in the LOD profile

dPercentage of the phenotypic variation explained by the locus at the peak position on the LOD profile

eAdditive effect of the identified QTL. Positive additive effect indicated the allele from IR24 increased the grain length–width ratio, and the allele from Asominori decreased the ratio. Negative additive effect indicated the allele from IR24 decreased the ratio, and the allele from Asominori increased the ratio
