shows the results of the PCA. It can be observed that the first<br>and second components explained 71.1% of the variance (PC1 explained<br>42.0%, while PC2 explained 29.1%). Fig. 1b reveals that PC1 can be considered an appearance (shape)/aroma and flavour dimension, with the<br>sensory attributes characteristic flavour of cherry tomatoes, sweet and<br>characteristic aroma of cherry tomatoes, juiciness, acid aroma and acid<br>taste located in the right side of the Fig. 1b, and pear shape in the left<br>side, mostly contributed to the variability associated with PC1. PC2 can<br>be seen as a texture dimension having the attributes firmness and crispness important role in characterizing cultivars. These results allow one<br>to identify the attributes that described each investigated accession,<br>according to those presented in Table 1. The location of the accessions<br>on the PCA (Fig. 1a) demonstrated the similarity between ENAS 1031,<br>the hybrid Super Sweet and the cultivar ‘Joanna’, being such tomatoes<br>similar to each other, and characterized by the acid aroma, characteristic<br>aroma of cherry tomatoes, sweet taste, chewing resistance, characteristic flavour of cherry tomatoes, sweet aroma, round shape, juiciness and<br>sweet taste. Such similarities can be seen also in Table 2. It should be emphasized that these attributes were the most important to the products'<br>characterization, taking into account the size of the vectors (Fig. 1b). The<br>Italian cultivar Cherry-Pachinowas also described as red, sweet and juicy<br>by the Italian trained panel (Pagliarini et al., 2001). On the other hand,
