Randomly amplified polymorphic DNA (RAPD) was used to investigate genetic relationships among 25 cultivars of cauliflower (Brassica oleracea var. botrytis L.). Forty decamer primers were examined, among which 15 primers produced polymorphism. Twenty-five polymorphic bands were observed, ranging in size from 428 to 1646 bp. A fingerprinting key was generated using these polymorphic bands. A dendogram was constructed using neighbour-joining analysis based on phylogenetic analysis using parsimony (PAUP). Results indicate that RAPD markers can be used for the routine identification of cauliflower cultivars within B. oleracea var. botrytis L.A R 0 3 0 1 2 F i n g e r p r i n t i n g c a u l i f l o w e r u s i n g R A P D m a r k e r s I .
