This study evaluates the combining ability and heterosis phenomenon in eggplant (Solanum melongena L.) parents to obtain valuable F1 hybrids. The research was conducted at the Plant Genetic Resources Bank (BRGV) Buzău and included 70 parental lines selected for genetic stability and distinct phenotypic expression. Testing the general (GCA) and specific (SCA) combining ability led to the identification of 31 hybrid combinations with high potential. The results indicated a strong manifestation of heterosis in most combinations, with 23 hybrids showing a 30% yield increase compared to their parents. Additionally, 35 hybrid combinations demonstrated high offspring uniformity, crucial in selecting new genotypes. In conclusion, the study highlights the importance of using local genetic material in eggplant breeding, contributing to reducing dependence on imported hybrid seeds. These findings offer promising perspectives for developing competitive hybrids adapted to local climatic conditions, thereby supporting the progress of the Romanian vegetable sector.
