AB  - Ethiopia's sesame productivity is low and below the world average. This low productivity is influenced by different yield limiting factors, the most important one is a lack of high-yielding improved varieties. It is basic to be understand the genetic variation and characters association. As a result, the objectives of this research was to determined the extent of genetic variation and its relationship to yield and 19 yield components. From 2017 to 2018, 100 genotypes were tested at Amibara in a 10 x 10 triple lattice design over two consequetive cropping seasons. Combined analysis of variance over the two years, the genotypes differed significantly for all of the characters considered.
