title: Genetic and biochemical  differentiation in Vitis vinifera (Kabarcik) populations grown at  different altitudes in Coruh Valley.
abstract: We  examined genetic differences of four Vitis vinifera populations (A, B,  C, D) including local Kabarcik cultivar grown along an altitude gradient of  800, 900, 1000, and 1150 m above sea level in the Coruh Valley (800 m: A  population; 900 m: B population; 1000 m: C population; 1150 m: D population).  Leaf samples were used for both RAPD and fatty acid analysis. A total of 60  individuals with 15 individuals per population were included in this study.  RAPD analyses showed various band sizes, which ranged from 250 to 3000 bp. Mean  polymorphic locus ratios were determined as 96.29% considering four  populations. The highest percentage of polymorphic loci (97.8%) was produced by  the highest altitude. Thirty-two different fatty acids were found; linoleic  acid was the most common in all four populations. According to the dendograms  obtained from statistical analyses of RAPD and fatty acid profiles the  populations that were close to each other in terms of geographical distance  also were similar genetically.
