Çaykara İlçesinde Yetiştirilen Yerel Armut (Pyrus spp.) Genotiplerinin Seleksiyon Yoluyla Islahı: I-Meyve Özellikleri.

This study was carried out in Çaykara county (Trabzon province, Turkey) and in its 25 districts during 2012-2013 years. In the research, pomological characteristics of localpeargenotypesgrown for many years were examined. 169 local pear genotypes were determined in the research. According to weighted-ranked method done based on fruit weight, rustiness, eating quality and appearance, 97 local pear genotypes were selected superior genotypes in 2012. In the study genotypes according to the first year harvest dates were divided into 3 groups as summer, autumn and winter seasons. Total 34 local pear genotypes (18 summer, 9 autumn and 7 winter seasons) were determined as promising according to weighted-ranked method in 2013. In the promising summer, autumn and winter genotypes, fruit weight were between 81.3 g-148.7 g, 88.5 g-155.7 g and 69.9 g-221.4 g,respectively; fruit width were between 49.9 mm-62.2 mm, 53,0 mm-65.4 mm and 49.3 mm-68.6 mm, respectively; fruit length were between 45.8 mm-78.5 mm, 54.3 mm-86.7 mm and 52.1 mm-91.1mm, respectively; fruit firmness were between 5.0 kg/cm2-9.8 kg/cm2, 6.8 kg/cm2-13.9 kg/cm2 and 4.8 kg/cm2-8.6 kg/cm, respectively; soluble solid contents were between 10.0 %- 14.4 %, 9.7 %-12.8 % and 11.3% -16.6 %, respectively; titrable acid contents were between 0.69 %-4.38 %, 1.43%- 7.63 % and 2.25%-16.0 %, respectively.
