Özet:

This study was carried out between 2019-2020 years in order to determine the high-quality types that are candidates to become a variety through selection breeding of the russian olives population that grows naturally in Iğdır ecological conditions. In this study, 124 russian olives genotypes were investigated and 22 genotypes were selected as promising according to the weighted rating method. In the investigated 124 genotypes, according to the two-year averages fruit weight were between 0.38-2.21 g, fruitwidth 12.01-18.13 mm, fruit length 12.61-29.69 mm, fruit volume 6.03-1.90 mL, titratable aciditiy 0.37-1.50 g 100 g-1and vitamin C 18.87-59.12 mg 100 g-1. Fruit weight, fruit width, frui tlength, fruit volume, titratable acidity, and vitamin C in the 22 genotypes which were selected as promising according to the weighted rating method were 0.81-2.02 g, 12.03-17.66 mm, 18.90-28.29 mm, 3.25-5.83 mL, 0.64-1.50% and 21.10-59.12 mg 100 g, respectively. As a resutl, among 22 promising genotypes selected by weighted rating method, 76 K 28, 76 K 30 and 76 K 38 genotypes had the highest score.
