Evaluation of Molecular and Essential Oil Diversity of Coriander (Coriandrum sativum L.) Landraces from Iran

Dr.Reza Omidbaigi

Abstract: Twenty coriander landraces selected from main cultivation area of Iran were
evaluated for molecular and essential oil diversity. The selected 15 RAPD primers, produced a total
of 261 scorable RAPD loci among which 90 were polymorphic (34.48 %). The average number of
bands was 17.4 for each primer. Genetic similarity calculated from the RAPD data ranged from
