Abstract

The present study aims to phenotypically characterize cherry tomato varieties from core-collection to obtain a new morphotype with distinct phenotypic expressiveness and qualitative characters. Breeding procedures were carried out both in protected and open field for all genotypes under study and the breeding methods used were classical breeding, segregation, and selection.  Following the breeding process, from the segregations obtained, a variety was selected in the F2 generation, genotype L 312 A, which proved to be phenotypically distinct. This genotype is part of the assortment of medium cherry tricolour tomatoes with high firmness, ovoid fruit weighing about 30 g on average, two seed lobes and a length/diameter ratio of 1-1.2. A new tricolour cherry tomato variety was genetically stabilized. It has distinct phenotypic expressiveness and superior quality traits. Prospects aim to approve and patent the variety.
