Evaluation of Genotype Coefficient of Variation (GCV) and Phenotypic Coefficient of Variation (PCV) of Seed Yield in Sesamum indicum Cultivars

Background and Objective: Performance is a complex trait influenced by various factors that are inherited in a polygenic manner and highly subject to environmental changes. Therefore, functional components that are less affected by the environment should be selected. The aim of this study was to evaluate the genetic parameters of seed yield in sesame cultivars. Materials and Methods: In addition, Genotype Coefficient of Variation (GCV) and Phenotypic Coefficient of Variation (PCV), heritability, genetic progress, the study of correlation between performance and its components and their relative contribution to performance in breeding programs are of great importance. Results: The results showed that the heritability of all traits was high, except for day to maturity, which had moderate heritability. The General Average (GA) was high for all traits except weight of 1,000 seeds, days to 50% flowering, capsule length, protein content, oil content and days to maturity. Conclusion: The study concludes that southern region of Ethiopia showed the highest seed yield. The heritability of all traits was high, except for day to maturity, which had moderate heritability.
