Mapping quantitative trait loci (QTLs) not only provides important useful information on the number and location of the loci that control quantitative traits, but also can be used in marker assisted selection programs. For QTL mapping of days to flowering, plant height, height of lowest primary branch, length of main infloresence, silique per main infloresence and silique density, 135 doubled haploid lines derived from the cross between a Korean spring line "Yudal" and a French winter line "Darmor" were evaluated using a simple lattice design with two replications at the Research Station of Agriculture and Natural Resources Campus of University of Tehran in 2007-2008. The genetic map of the doubled haploid population was constructed using 459 molecular markers including isozymes, RFLPs, RAPDs, SSRs and SNPs. Using the composite interval mapping method 4, 5, 3, 2, 3 and 4 QTLs were detected for days to flowering, plant height, height of lowest primary branch, length of main infloresence, silique per main infloresence and silique density, respectively. Most of the QTLs were located on DY13 and DY6. These two linkage groups seem to be of great importance in controlling the studied traits.
