Evaluation of agronomical and qualitative characteristics of Greek Oregano (Origanum vulgare ssp. hirtum) germplasm for breeding purposes

Oregano (Origanum vulgare) is one of the most commercially valued species with remarkable biological properties, while its world trade and consumption is steadily increased. In order to identify a standardized plant material of Greek Oregano (Origanum vulgare ssp. hirtum), sixteen native populations collected from different regions of Greece, were evaluated for their essential oil yield and composition. A breeding program was initiated for the most effective populations, concerning the most desirable biochemical, agronomic and morphological characteristics, using pedigree method and honeycomb design for plant selection.
