“…Heritability is the proportion of variation in a trait that can be attributed to inter-individual genotypic variation. If a character has a high heritability, it means that its variation in the population is mostly influenced by the genetics of each individual, while, if it has a low value, the environment surrounding each individual and gene-environment interactions will have a fundamental role in determining the heritability of the variation of this trait (Falconer and Mackay 2006) (concepts recently applied by Fernandes et al 2022).…”

“…Heritability has been widely studied in plant breeding, being estimated in a broad sense as the proportion of observed variability caused by total gene effects and their interaction with the environment (Falconer and Mackay 2006) (Mousavi et al 2019, Fernandes et al 2022.…”

“…However, changes in this idea led to the so-called broad sense heritability (H 2 ), which involves the proportion of the variance that is due to all genetic effects and heritability in the narrow sense that the proportion of variance is due to the additive effect.. The most important role of estimating heritability is to predict genetic gain (Falconer and Mackay 2006) (e.g., applied by Fernandes et al 2022).…”

The olive tree (Olea europaea L.) is a species of great importance in history and economic, with large phenotypic variability, represented through a wide range of cultivars spread throughout the world. There are several studies on the characterization of a large number of cultivars of the species. However, there is a need to uncover how these phenotypic traits are heritable, and how they can change when environmental conditions vary. For this reason, the objective here was to estimate the heritability coefficients for fruit characters in six commercial cultivars, analyzed under conditions in the state of Rio Grande do Sul, Brazil. The study was carried out in a single year, based on the analysis of fruit and oil traits on the cultivars Arbequina, Arbosana, Frantoio, Koroneiki, Manzanilla de Sevilla, and Picual, under environmental conditions in the state of Rio Grande do Sul. Phenotypic plasticity and broad-sense heritability were estimated in both inter and intra-cultivar comparisons. From the analyses of variance and heritability, it was observed that some cultivars such as Koroneiki or Picual had their characters mainly under genetic control, while Arbequina was more influenced by genotype-environment interaction.The information derived from this work can help guide the selection of cultivars that are best adapted under the local environments of the southern region of Brazil.
