In the period 2000 to 2002, 22 varieties of potato (Solanum tuberosum L.), i.e.: 'Adora', 'Jaerla', 'Minerva', 'Primura', 'Vesna', 'Arinda', 'Bintje', 'Carlingford', 'Concorde', 'Cosmos', 'Cvetnik', 'Desiree', 'Escort', 'Frisia', 'Romano', 'Sante', 'Agria', 'Bright', 'Cita', 'Cornado', 'Fianna' in 'Kennebec' have been grown in collection plantations of Biotehnical Faculty. The highest average (three years) yield among early varieties was observed at 'Jaerla' (40.0 t/ha), among medium early varieties at 'Arinda' (45.3 t/ha), among medium late varieties at 'Escort' (47.5 t/ha) and among late varieties at 'Agria' (47.0 t/ha). Based on sensorical tests, an expert instructed group consisting of 8 to 10 students, evaluated following characteristics of the peeled potatoes: the colour change of potato surface, overcooking properties, consistency (compact - loose), flouriness, viscosity, moisture - dryness, texture (rough - fine), flavour (preferred - foreign). Only variety 'Carlingford' with the average yield of 38.1 t/ha got the excellent average (three years) mark (10). 9 varieties, including medium late variety 'Desiree' with average yield 45.5 t/ha, were evaluated with the mark 9 to 10. In spite of being the most known and popular variety in our country, recent varieties like 'Minerva', 'Arinda', 'Carlingford', 'Escort', 'Frisia', 'Agria' and 'Cita' will probably win consumers recognition only after better collaboration between experts and producers. As well, consumers will find the potato gastronomic excellency only after recognition of sensorical characters and after selection of usage-defined consumptive type of potato, what can be achieved by distribution of professional information in various (audiovisual) media.
