Abstract: Potato seed production represents a major interest of scientific research for this culture. Hydroponic system offers possibilities of production minitubers, with a superior sanitary quality. During the year 2009, the varieties Ostara, Christian, Roclas were experimented at National Institute of Research and Development for Potato and Sugar Beet Brasov on this system, comparative with classical technology on culture in greenhouse, using as biological material minitubers and plantlets. Analyzing the behavior of this varieties on different sublayers culture (expanded clay granules, perlite, soil), resulted a difference between experimented varieties and sublayers used. Christian and Ostara varieties have been registered the best results, concerning the minitubers number/plant, with values between 6.5 and 7.66 minitubers/plant. Using of hydroponic system had a positive influence on the minitubers number/plant, comparative with classical method of culture in greenhouse, on soil. This had been reflected by production of a big number of minitubers/plant, on the sublayer with expanded clay (8.25 minitubers/plant), followed by the sublayer with perlit (6.41 minitubers/plant). From view point of interaction between varieties and culture sublayer, concerning minitubers number/plant, the highest values were find at Ostara varieties on sublayer with expanded clay granules (10.5 minitubers/plant), followed by Christian on sublayer with perlit (9.5 minitubers/plant. Regarding the minitubers distribution on calibration class, the highest frequency of minitubers production is on calibration class 15-25 mm (for 9 cases), followed by calibration class <15 mm (8 cases). At calibration class 35-45 mm, production rate is very small (discovering only at Ostara variety in 3 cases). The influence of sublayer culture on size order of minitubers is reflecting by appearance of all calibration classes for the 3 sublayers, but with preponderance , the highest values are finding al 15-25 mm calibration class with a sum up value of 7.4 minitubers and 7.2 minitubers for calibration class <15 mm. Regarding the total weight of minitubers obtained/ plant , analyzed in function of sublayer, it may be note the positive influence of sublayers with expanded clay granules and perlite, used on hydroponic system, towards the soil, used in classical technology, the values being close between the two kinds of industrial sublayer (values with 34.27 and 33.27 g).
