Integration of AFLP s, SSR s and SNP s markers into a new genetic map of industrial chicory ( C ichorium intybus L . var. sativum )

A chicory genetic map of 1208 cM has been created using 247 F 2 plants and 237 markers (170 AFLP , 28 SSR , 27 EST ‐ SNP and 12 EST ‐ SSR ). This map covers 84% of the chicory genome. The chicory‐genic‐markers‐associated sequences were used to find potential orthologs in mapped lettuce EST s from the C ompositae G enome P roject D atabase. Twenty‐seven putative orthologous pairs were retained, pinpointing seven putative blocks of synteny that covered 11% of the chicory genome and 13% of the lettuce genome, opening new perspectives for the analysis of these two species.
