FIELD PERFORMANCES OF SOME LOCAL POTATO CULTIVARS FROM EASTERN TURKEY IN THE AEGEAN REGION

Nine local potato cultivars from Eastern Anatolia selected in the seedbed growing stage were tested for agronomical performance in a field trial arranged in the Randomized Complete Block Design with 3 replications at Bornova in 2014 and 2015. Based on the multiple comparisons, local potato cultivar Posof had the highest means for plant height (60.5 cm), stem number (4.9), leaf number (89.9), leaf width (2.4 cm), tuber number (11.2), plant yield (762.7 g) and plot yield (3.8 kg). Local varieties Pasha (4.2 cm), BCB (4.2 cm) and Pasha plateau (4.2 cm) over passed Posof for only leaf length. Local cultivar ABK had the highest means for single tuber weight (81.6 g), tuber length (6.4 cm) and tuber width (4.8 cm). Local varieties PC (10.8) and Pasha (9.9) had high means for number of tubers. Also Pasha (589.4 g), Bayburt (522.7 g) and ABK (563.8 g) had high plant yield. It could be concluded that Posof had superior performance in the Aegean Region as compared to the remaining. Posof, Pasha, BCB, Pasha-plateau, ABK and Bayburt could be further tested in the regional variety testing trial as well as to be used as parents in the breeding programs for the Aegean Region.
