This study was carried out as random blocks experiment design that three recurrent in Van ecological condition in 2009 infour sowing time (April 5 and 20, May 5 and 20) which to determine essential oil ratio and components of one local coriander population and two coriander varieties. The highest essential oil ratio was obtained as 0.45% from Gurbuz variety. The highest essential oil ratio was obtained as 0.5% from May 20 sowing time.

Linalool which essential oil component ratio was changed from 68.3-74.8%. Gamma terpinen ratio was changed from 7-8%. The highest gamma terpinen ratio was obtained as 8.8% from April 20 sowing time.
