Abstract
The research was conducted at Al-Jmmaseh Station, Agricultural Research Center in Tartous, Syria, during 2014 season, to study the phenotypic correlation and path coefficient of pericarp thickness (mm), firmness (Kg/cm3), total soluble solids (%), yield per plant (Kg/plant), number of locales per fruit, fruit diameter (cm), and fruit length (cm). Fifteen hybrids and their parents were evaluated with three replications using RCBD design. The results of phenotypic correlation values showed that fruit firmness was positively and significantly correlated with total soluble solids (r=0.319*) and pericarp thickness (r=0.779**), but it was negatively and significantly correlated with yield per plant (r=-0.492**), fruit length (r=-0.439**), fruit diameter (r=-0.685**) and number of locales per fruit (r=-0.649**). Path coefficient analysis showed that pericarp thickness was one of the most traits in contribution in firmness variation, therefore, it could be concluded that firmness improvement could be achieved by selection for pericarp thickness.
Key Words: Tomato, Phenotypic correlation and path coefficients.
