The creation of varieties with high biological resistant to specific diseases of the vine but also to the extreme weather conditions (frost) represents a great advantage by being able to avoid phytosanitary products. But besides these goals, the breeder must have into account the productivity and quality, these characters being of major importance for the farmer. In the natural conditions of Blaj vineyard, in 2013, the registries results show that ‘Brumăriu’ obtained the biggest values for: sugar level (195.7 g/l), absolute fertility coefficient (1.7), relative fertility coefficient (1.6) and relative productivity index (239.5 g). The most early variety was ‘Rubin’, witch maturated at 20th of september. ‘Radames’ offers high productivity (over 25 t/ha) but the destination is for getting current consumption wines.
