A highly economic important crop, potato is grown in more than 100 countries and is the fourth consumed food in the world. Twelve Romanian potato varieties were investigated for their growth parameters and yield to determine suitability for production. Experiments were conducted to National Institute of Research and Development for Potato and Sugar Beet Brasov using a randomised block design with four replications. Determination of the tuber number and their mass was done in each repetition. The potato yield was determined in each elementary plot and the yield per hectare was calculated. Darilena produced the tallest plants (90.5 cm) and Castrum. produced the shortest (58.88 cm). The number of stems per hill ranged from 2.5 cm (Foresta cv.) to 9.25 cm (Marvis). Tuber weight average per hill ranged from 2055 g (Sarmis) to 500 g (Castrum). Ervant (37.44 t/ha) and Azaria (37.94 t/ha) records superior productivity and Asinaria and Darilena showed adaptability to climate conditions and suitability for culture under high economic efficiency. Specific technologies must be established for each variety to reach the maximum potential in periods of stress that occur due to climatic variations.
