Tomato (Lycopersicon esculentum Mill.) is vegetable which could be produced and consumed in a many different ways, due to its variability, made by breeding programs. Variability of analyzed genotypes was determined for following fruit traits: average mass, fruit shape, locules number, and dry matter content. Variability source structure was determined using principal components analysis (PCA). Three main components, which explain 94.2% of total variability, were chosen for further analysis. The biggest part of the first main component has fruit shape and locule number. The second component is determined by dry matter content, and the third by the fruit mass. For more precisely perception of homology and divergence between analyzed genotypes, non hierarchical grouping analysis (k-means) was performed, and genotypes were divided into three groups. Divergency was determined for fruit mass and locule number, while for index shape and dry matter content analyzed genotypes are homogenous.
