Abstract
The random amplified polymorphic DNA (RAPD) technique was adapted for segregation analysis in sugar beet. 83 IO/I individuals were scored with a set of 20 arbitrary decamer primers. 4 preliminary linkage groups could be established, enclosing 9 RAPD markers, 2 isozyme loci, a gene for the hypocotyl colour and a gene for resistance to the root knot nematode (Heterodera schachtii Schm.).
