Abstract :This study was carried out to determine some morphological characteristics of 94 tomato genotypes at the S4 level and to reveal the relationships between these materials. In the study, leaf attitude, leaf length, leaf width, number of flowers, fruit color, fruit weight, fruit width, fruit length, the thickness of pericarp, fruit shape, fruit diameter, number of locules, and total soluble solid content insert ignore into journalissuearticles values(TTSC); were measured and observed in these genotypes. As a result of the phenotypic assessment, the maximum fruit weight values of the genotypes were observed as in G9 insert ignore into journalissuearticles values(317.59 g);, G54 insert ignore into journalissuearticles values(310 g);, G92 insert ignore into journalissuearticles values(292.85 g);, G70 insert ignore into journalissuearticles values(287.01 g);, and G110 insert ignore into journalissuearticles values(276.66 g);; and the lowest fruit weight values were observed in G26 insert ignore into journalissuearticles values(18.302 g); and G8 insert ignore into journalissuearticles values(14.48 g);. Average fruit length, fruit width, pericarp thickness, and the number of carpels were recorded insert ignore into journalissuearticles values(69.09 mm, 56.90 mm, 6.37 mm, and 4 carpels respectively);. Tomato genotypes were also investigated using Cluster and Principal Component Analysis insert ignore into journalissuearticles values(PCA); method based on these measurements and observations. As a result of this analysis, five independent principal component axes were obtained. While these axes represent 69.28% of the total variation, the eigen values were ranged between 1.06 and 4.02. According to the PCA analysis results, genotypes G7, G81, G93, and G103 were prominent in terms of leaf length, fruit width, fruit weight, and carpel number parameters. Based on TSSC results, the G65 genotype was found to be the most prominent one, and the genotypes G12 and G114 exhibit promising results for fruit color. A high degree of morphological variation was detected among tomato genotypes.
