Morphological Characterization of Pear Genotypes in Eastern Anatolia Region

This study was carried out between the years of 2010 and 2011 in erzincan horticultural research station. the pear genotypes used in this study was collected and kept at collection parcel within the context of eastern anatolia fruit genetic resources project since 1994. morphological characterizations of pear genotypes were done according to upov criteria‟s. ripening period, morphological, phenological, pomological and chemical characteristics of pear genotypes and theirdegrees of genetic affinity have been defined within this study. while nineteen pear genotypes were flowered and produced fruit in first year (2010), this number has decreased to seventeen genotypes in the second year (2011). because of difference in the number of genotypes, evaluations were done individually within the years. half of pear genotypes have grown semi vigorously, duration from full blossom until harvesting was 126 days for (6/3) and 163 days for (7/6) genotypes. fruit weight ranged between 34.06g (3/3) – 476.41g (2/6) in 2010, and 30.77g(2/4) – 240.76g (5/4) in 2011. tss content changed between 13.4% (3/3) and 20.8% (9/5) in 2010, and 10.0% (14/2) to 18.2% (2/5) in 2011. dendrogram of pear genotypes were determined 3 different major groups each years. pear genotypes numbered as 1/2, 1/6, 3/2, 5/4, 9/6, 11/6, 12/4 and 14/2 can directly be taken into the production. further studies should be conducted to characterize molecular identification of thesegenotypes.
