The experiments were conducted in two successive vegetation seasons of 2013 and 2014 at the Isparta and Eskisehir ecological conditions. The aim of this study was to determine the performance and stability of coriander genotypes for yield and yield components and essential oil content. In the study, Gamze, Kudret, Erbaa, Arslan and Pel-mus coriander cultivars and Burdur, Antalya and Tokat genotypes were evaluated growing seasons of 2013 and 2014 under the Isparta and Eskisehir ecological conditions in Turkey. Years and locations with different climatic and geographic characters had significant effects in coriander genotypes for yield, yield components and essential oil content. Increase in seed yield and decrease in essential oil content occurred with increasing rainfall. Results revealed that Arslan cultivar in Eskisehir location and Kudret in Isparta location had the highest seed yield. Besides Kudret cultivar and Gamze cultivar gave the highest seed yield as a means of locations; Eskisehir location had also higher seed yield.
