Karyotypes of 40 accessions representing 10 different Lactuca species were studied in detail. Karyological features were numerically analyzed. The cluster analysis of the collected karyological data indicated significant inter- and intra-specific differences for all variables measured. L. sativa and L. serriola had similar karyotypes, suggesting close relationship of these species.
