Abstract
Mapping chromosomal loci responsible for seven morphological and five biochemical traits of quality in populations of doubled haploid lines of leafy, rooted, and oilseed crops of Brassica rapa L. species was performed for the first time. In total, 140 quantitative trait loci (QTLs) were mapped determining manifestation of the studied morphological and biochemical economically important traits of quality under field and greenhouse conditions; the control of the same traits under different growth conditions or simultaneous control of several traits by one locus were noted. Molecular markers genetically linked with the selected QTLs were detected. The block genomic structure of the genetic components (chromosomal loci and linkage groups) determining manifestation of morphological and biochemical traits of quality that make B. rapa plants nutritionally valuable is discussed for the first time. The conclusion is drawn that the revealed QTLs and identified molecular markers may be of interest for the forthcoming study of genetic control by them of economically important characters and for the marker assisted selection in B. rapa.
