Sweet cherry and sour cherry production in Turkey occupies an important place in worldwide production and is still of considerable importance in terms of providing further fruit species and gene resources. In this study, 88 sweet cherry, 16 sour cherry, and 9 mahaleb types displaying potential for cultivar rootstocks were selected from wild cherry populations in Samsun Province of the Central Black Sea Region in Turkey. | Turkish Journal of Agriculture and Forestry Research Article Turk J Agric For (2013) 37: 575-584 © TÜBİTAK doi: Morphological characterization of cherry rootstock candidates selected from Samsun Province in Turkey 1, 1 2 Aysen KOÇ *, Şükriye BİLGENER Department of Horticulture, Faculty of Agriculture and Natural Sciences, Bozok University, Yozgat, Turkey 2 Department of Horticulture, Faculty of Agriculture, Ondokuz Mayıs University, Samsun, Turkey Received: Accepted: Published Online: Printed: Abstract: Sweet cherry and sour cherry production in Turkey occupies an important place in worldwide production and is still of considerable importance in terms of providing further fruit species and gene resources. In this study, 88 sweet cherry, 16 sour cherry, and 9 mahaleb types displaying potential for cultivar rootstocks were selected from wild cherry populations in Samsun Province of the Central Black Sea Region in Turkey. The morphologic characteristics of the studied genotypes were compared with the standard clone rootstocks PHL-A, MaxMa 14, Montmorency, Weiroot 158, Gisela 5, Gisela 6, and SL 64. A total of 22 morphological and phenotypic characteristics were evaluated in the selected genotypes and clonal rootstocks. The obtained data were analyzed by using principal component analysis, and 7 principal component (PC) axes accounted for of the total cumulative variation. The first PC axis, which accounted for of the total variation, was represented by leaf blade length, leaf blade width, petiole length, ratio of 1-yearold shoot internodes length, and 1-year-old shoot branching, while the second PC axis, which accounted for of the variation, was represented by leaf blade ratio of length to width, 1-year-old shoot length, 1-year-old shoot thickness, and leaf blade shape. Average linkage cluster analysis was also performed, and 7 main
