QTL mapping of esterase isozyme forms in Brassica rapa L. mature seeds

G their genetic control retain their relevance, allowing researchers to reveal the fine mechanisms of the relationship of the organism with the environment and homeostasis and to develop effective biochemical markers for rapid assessment of genetically and selectively significant material. In this paper, the chromosome loci responsible for the activity of 13 different esterase forms of mature seeds in Brassica rapa L. were identified and mapped for the first time. The doubled haploid lines of two mapping populations, DH30 and DH38, were studied. All identified esterase isoforms were divided into three groups according to their electrophoretic mobility. The group of isoforms A1-A3 had a high molecular weight and low electrophoretic mobility. The group of B1-B7 isoforms exhibited an average molecular weight and an average electrophoretic mobility. The C1-C3 group consisted of isoforms having a low molecular weight and, consequently, the highest electrophoretic mobility. Each of the parental forms, as well as each of the studied lines of mapping populations, had its own unique electrophoretic spectrum of esterase isoforms...
