Interpretive Summary:

Technical Abstract: Genetic linkage map is being constructed for watermelon based on a testcross population and an F2 population. AFLP markers appeared to be clustered on linkage regions, while SSR, ISSR and RAPD markers are randomly dispersed on the genome. AFLP markers also have greater genetic distances between them as compared with SSR, ISSR and RAPD markers, resulting in significant increase of map distance. Similar results with AFLP markers were also shown in mapping experiments with an F2S7 recombinant inbred line (RIL) population that was recently constructed for watermelon. Marker order appeared to be consistent in linkage groups derived from a testcross and an F2 population. Experiments with SSR and EST markers are being conducted to saturate the linkage map of watermelon genome.
