The absence of local hybrids for greenhouses imposed starting an intensive breeding program at V.R.D.S. Buzau since 1996. The main purpose of the program is obtaining valuable hybrids which show strongly F1 heterosis. Through inter and intraspecific hybridization works in Solanum genus, besides disease resistance inheritance, valuable features can be obtained: genetical resistance at extreme weather, extremely high or low temperatures, water stress or salinity (Downey M.C.,1991). Obtaining productive hybrids with genetical resistance at Verticilium dahliae fungus allows the elimination or the decrease of chemical treatments which would lead to cost reduction and environmental pollution decrease (M. Tudor,1996). After evaluation and intensive breeding work with germplasm resource, it was obtained a number of 22 stable genitors. After general and specific combining ability were obtained a large number of hybrid combinations. L1 A and L1 S hybrid showed F1 superiority and phenotipical uniformity, obtaining H1 Buzau F1 hybrid in 2010. Comparative crops both from greenhouses and field revealed valuable genetical resource which demonstrated phenotipically reproductive and adaptive heterosis and also high productivity and ecological plasticity.
