The goal of Romanian tomato hybrid favored the introduction of foreign cultivars usually inadequate for our climaticconditions. VRDS (Vegetable Research and Development Station) Buzau has tradition for tomato breeding, wereachieved many cultivars that have demonstrated their genetic stability, durability and performance in crop production.Special attention was to establishment the germplasm resource; the collection presently holds a total of more than 800genotypes in various breeding stages. After evaluating the germplasm collection, valuable genotypes have demonstratedgenetic stability and useful features for the breeding process and were promoted from field collection in field work.Selected genotypes were subjected to intensive breeding work, the general and specific combinative capacity was tested,thus achieving a large number of hybrid combinations. To obtain new hybrid creations were detained genitors andhybrid combinations that showed the heterosis phenomenon in F1. Nineteen hybrid combinations manifested heterosisphenomenon clearly and was used as reference 'Siriana F1’ hybrid. Hybrid combinations that exceeded significantly'Siriana F1’ regarding the quality and yield, will be proposed for approval at ISTIS.
