This paper provides the first description of a consensus map of the cultivated sunflower genome (Helianthus annuus L., n=17 chromosomes), based on RFLP. A total of 180 probe-enzyme combinations were mapped on at least one of five segregating progenies (three F2 and two BC1 populations), revealing 237 loci that did not show any distortion of segregation. The consensus linkage map obtained with these loci covers 1150 cM and consists of 16 linkage groups of more than 20 cM, 7 groups of less than 20 cM and 18 unlinked loci. The mean distance between loci is 7 cM, but in some regions intervals of 20 cM remain. Genotypic and gametic segregation distortions affect about 7% of loci. It was found that 25% of the probes mapped using several different restriction enzymes or that on different progenies they revealed 2 or more loci.
