Abstract:\u00a0<\/strong><\/span><\/p>\n

The study was conducted in Al-Jamasah station, Tartous agricultural research center, Syria, during 2019 and 2020 seasons. using Randomized Complete Blocks Design (RCBD) with three replications was used. Generation mean analysis method to estimate the type of gene action using some genetic indices of the six population of two individual hybrids of tomato (T2\u00d7T8) and (T8\u00d7T16). (Single plant yield, pericarp thickness, firmness, total soluble solids, dry matter, total sugars and titratable\u00a0acidity), were studied. The results revealed similar values for the phenotypic and genetic variation coefficients in the two hybrids; and high values for the degree of heritability in the broad sense, which reflects the high influence of the genetic component and the low influence of the environment on the phenotypic expression of all the studied traits. On the other hand, it gave moderate values for the degree of heritability in the narrow sense for the traits of Single plant yield and pericarp thickness, which indicates that the additive and non-additive gene actions controlled inheritance of these two traits, and high values for the traits of firmness, total soluble solids %, dry matter %, total sugars %, and titratable\u00a0acidity. which indicates the importance of additive genetic action in the inheritance of these traits. The analysis of the average generations showed that the additive and dominance gene actions were significant for most of the studied traits, with superiority of the dominance gene action values. Epistasis gene action from the additive \u00d7 additive and dominance \u00d7 dominance types contributed in the inheritance of most of the studies traits. The contrast between the two signs of the dominance and the epistasis gene actions from the type (dominance \u00d7 dominance) in most of the traits indicated that it was from the duplicate type in majority of the studied traits and consequently selection could be conducted in later selection.<\/span><\/p>\n
