without heat and in open field. Crop technologywas the classical one for each system. Tohighlight the main parameters of the newhybrid, Aragon by Hazera, a top market hybridwas used as monitor.The main data from theboth crop systems measured at genitors, newhybrid and monitor plants and fruits arepresented in table nr. 1,2, 3 and 4:Figure 1. HybridizationAs novelty in hybridization process (Figure 1)was the implementation of a new technologymethod of pollen transfer from maternal topaternal genitor. This method was elaborated atV.R.D.S. Buzau and consists of using a liquidsolution of water and sugar or honey mixedwith patern pollen and then the flowers aresprayed bathing with this solution. Thismethod has many advantages as:-the liquid solution feeds and hydrate pollengrains giving them long life and resistance todrought.- adding pollen grains to female flower is asofter action avoiding aggression andmutilation.- sugar or honey are adherent so they are fixingthe pollen grains to flower stigma avoidingpollen release.-higher efficiency, secure and easer work in thehybridization process.Table 1.

In what concerns plantheight, genitor L1 A range first followed by H1Bz. In what concerns shoots number/plant, H 1Bz came first followed by monitor. The bignumber of leafs, superior to genitors andmonitor hybrid demonstrates that this plantmanifest somatic heterosis which is animportant feature for breeding. Altoughgenitors of the hybrid have erect habit, F1hybrid resulted has an uniform globular shaperesembling with the one of monitor. Plantdiameter highlights increased vigor of thehybrid from both genitor and monitor.RESULTS AND DISCUSSIONSThe research undertaken at this species from1996 since now had finished with valuableresults:-it was constituted and conservated agermplasm resource of which could beobtained new valuable creations-were obtained 22 important genitors with highability to create new varieties and hybrids-the entire collected material was tested forgeneral and specific combining ability and theresults were saved on computer-H1 Buzau F1 hybrid was obtained in 2010which meets the main proposed objective.H1 Buzau F1 hybrid was studied 3 years afterthe release in two crop systems: greenhouse246Table 2.
