Molecular markers were identified in the F2 generation originating from a cross between plants of sugar beet and garden beet. From the total number of 231 AFLP and 30 RAPD markers identified in the studied population 119 AFLP and 5 RAPD markers, showing segregation not significantly different from the expected 3:1 ratio, were used to construct genetic maps. Two genetic maps of beet were obtained; the first with 73 markers identified in plants from the paternal line, and the second with 51 markers characteristic for plants from the maternal line. Six linkage groups were identified within each map. The relation between the maternal and paternal linkage groups is as yet unknown.
