Özet

This study described some desirable pomological and chemical traits of 10 local pear varieties from Usak in 2016. In these local pear varieties, some pomological and chemical properties were determined such as fruit weight, fruit height, fruit widths, fruits firmness, total soluble solids, titratable acidity, DPPH (2,2-diphenyl-1-picryl-hydrazyl-hydrate) free-radical values and ascorbic acid content. The values for fruit weights ranged from 93.12 +/- 3.26 g to 287.93 +/- 8.36 g, fruit height ranged from 6.12 +/- 1.37 cm to 11.62 +/- 1.15 cm, fruit widths ranged from 4.38 +/- 0.82 cm to 8.52 +/- 0.63 cm, fruits firmness ranged from 4.26 +/- 0.18 lb to 11.19 +/- 0.32 lb total soluble solid contents ranged from % 8.62 +/- 0.32 to % 17.20 +/- 0.83 and, titrable acid contents ranged from % 0.43 to % 2.63. DPPH values were determined and varied from 12.37 +/- 0.73 to 26.74 +/- 1.68; ascorbic acid content situated between 108.53 +/- 3.12 and 263.37 +/- 4.71 mg. We conclude that some local pear varieties may be recommended for the next breeding studies.
