Abstract :Availability of genetic variability among a certain crop population and knowledge of the genetic parameters of yield and yield-related traits are the key preconditions to enhance seed yield. Therefore, sixty-four sesame genotypes consisting of fifty-nine accessions and five varieties were assessed in order to evaluate sesame genotypes for yield and yield-related traits and estimate the genetic parameters. An 8 x 8 simple lattice design was used to evaluate the experimental materials. Data were collected for the twenty traits. Analysis of variance revealed that sesame genotypes were significantly different insert ignore into journalissuearticles values(P<0.05); except for internode length and seed shattering-related traits. ASARC-ACC-SG-013 was the highest-yielding accession, while accession GK-012 insert ignore into journalissuearticles values(2); gave the highest oil content insert ignore into journalissuearticles values(60.09%);, and the mean thousands seeds weight ranged from 2.00 g to 2.75 g, indicating the existence of elite sesame genotypes that can be considered to maximize yield, seed size, and oil content. The number of primary branches plant-1, the number of capsules on the main stem plant-1, and total capsules plant-1 all showed high coefficients of variation, demonstrating that the genotypes under study had sufficient variability for these traits. High heritability and genetic advance were obtained for traits such as plant height to the first branch insert ignore into journalissuearticles values(60.70%; 21.90%);, capsule length insert ignore into journalissuearticles values(81.10%; 24.00%);, primary branches plant-1 insert ignore into journalissuearticles values(63.10%; 36.30%);, number of capsules on the main stem plant-1 insert ignore into journalissuearticles values(74.40%; 45.80%);, and total capsules plant-1 insert ignore into journalissuearticles values(64.90%; 51.40%);. Thus, the finding suggests a trustworthy estimate of the genetic advancement that may be anticipated through phenotypic selection for these traits.
