The purpose of the study was to investigate biological and economic qualities of nine potato cultivars Iverce, Nadezhda, Perun, Rozhen, Orfei, Evridika, Kalina, Bor, Struma bred in the Maritsa Vegetable Crops Research Institute, Plovdiv and Experimental Potato station, Samokov. Cultivars were tested during the period 2009 – 2011 under the requirements of late production in region of the village of Pavelsko, located in Rodopes Mountain at altitude 1600 m. The experiments were conducted by using the block method in 12 variants 9 Bulgarian cultivars and the standard cultivars – Impala, Sante and Agria, in 4 replications 100 plants per replication. The parameters of the basic characters as plant height, stem number, duration of vegetative period, number of tubers per plant, mean tuber weight, shape, shallowness of eyes, standard and total productivity have been established. On the average for the studied period six of the Bulgarian cultivars Nadejda, Perun, Rozhen, Orfei, Kalina, Bor exceeded by yield controls with 6 to 29%. These cultivars show the most intensive tuberformation, the quickest tuberization and the highest portion standard productivity.
