Abstract

Abstract: To study essential oil content along with some agro-morphological traits of ajowan, eight different ecotypes from North west, center, south and east of Iran, were evaluated. The results of analysis of variance revealed significant difference among investigated ecotypes of ajowan for following characters including plant height, number of branches, number of umbels, number of umbellets in an inflorescence, biological yield and single plant yield at 1% probability level, and for number of secondary branches and oil content at 5% probability level. According to results of mean comparison analysis using Duncan multiple range test at 5% probability level the highest means of biological yield, single plant yield and oil content percentage were related to Shiraz ecotype. According to high correlation analysis between grain and oil yields, breeding for these two traits can be consistent in Iranian ecotypes of ajowan. Oil contents percentage in ecotypes from south and center were more than other parts of Iran.
