Using of the DH–lines of two mapping populations of Brassica rapa L, the morpho–biological investigation and mapping of QTLs determined some morphological traits of quality in greenhouse's condition have been done. The linkage groups of QTLs of the following quantitative traits have been identified and localized: length, width, color, hairiness, and surface of lamina, as well as petiole length and width caused of nutritive value of B. rapa plants. The molecular markers genetically linked with mapped QTLs were revealed. The percent of phenotypic variability determined by the identified chromosome loci was calculated.
