Yekta was created in 1981 from crossing between B5 ? M7 and an early maturing Palistinian line, in Oil Seed Crops Research Department of Seed and Plant Improvement Institute (SPII) at Karaj. The pure line of the cross was obtained after five years of selection with pedigree method. Preliminary evaluation of the line along with other 31 selected lines was done in 1989 and Yekta together with other 13 advanced lines were selected and further evaluated for two more years started in 1990.Results showed that Yekta with average yield of 1955 kgha-1 was superior to the check cultivar and other lines in the trial. In advanced yield trial which was conducted in Karaj, Sari and Moghan from 1990 to 1992, Yekta with average yield of 1331 kgha-1 was found as a superior and stable line. This cultivar is early in maturity and recommended for northern parts of Iran with altitude of more than 1000 meter abave the sea level and for the areas with short growing season that the late maturing cultivars of sesame usually do not perform well
