The estimation of heritability is critical in selecting breeding strategies for various characteristics of agricultural plants. A randomized complete block design (RCBD) with four replications was used at Moghan Agricultural Research Station in Iran during the 2017-2018 crop years to evaluate heritability and genetic efficiency in 14 advanced sesame lines, and the Oltan cultivar was used as a control variety. The number of days to flowering (DF), growth period (GP), plant height (PH), number of capsules per plant (CN), capsule length (CL), 1000-seed weight (SW), seed (SY), and oil yield (OY) were all measured during the experiment. Selected sesame lines were utilized to estimate genetic parameters, heritability, and genetic advance using the REML/BLUP method. The results revealed moderate GCV (Genotypic Coefficient of Variation) and PCV (Phenotypic Coefficient of Variation) values for CN (13.58, 17.24), SY (14.45, 17.74), and OY (15.08, 18.15), whereas the other traits had lower values. Moderately high heritability (broad sense) with high GAM (Genetic Advance as a Percentage of the Mean) was found in CN, SY, and OY, while low heritability and low GAM were found for phenological traits, DF, and GP. It may be stated that the selection strategy used in sesame breeding lines in terms of CN with moderately high heritability (broad sense) and high GAM, as well as a strong positive correlation of CN with SY and OY, could reach maximum efficiency, with which it provided the high-yielding genotypes that were needed for its breeding program.
