In this study, natural populations of E. italicum distributing in 6 squares according to grid<br />

system of Turkey were analysed based on RAPD, fatty acid and micromorphological patterns<br />

of the seeds. It was detected some minor differences in seed morphology and the surface<br />

sculpturing. Total oil concentrations ranged from 19.3 (A2(E)) to 23.5% (A1) among the<br />

populations. Some variations of fatty acid quantities were also observed. Major unsaturated<br />

fatty acids were alpha-linolenic, linoleic, oleic, stearidonic and gamma-linolenic acids<br />

respectively. Significant differences were found for whole series and some proportions of the<br />

fatty acids (p
