Genetic and linkage analysis of marker loci were performed with 4 selfed progenies, derived from single plant (I0/1 lines) of carrot (Daucus carota L. sativus). The analysis of 58 markers included 1 morphological marker, 10 isozyme loci, 14 RFLPs, 28 RAPD markers, and 6 isolated PCR fragments used as RFLP probes. Linkage analysis was carried out with the MAPMAKER program and resulted in the construction of 8 linkage groups containing 55 markers with an average distance of 13.1 cM, 3 marker loci remained unlinked. 24% of the markers deviated significantly from the expected Mendelian ratios (1:2:1 or 3:1) due to gametic or zygotic selection.
