Determination of phenological, pomological and morphological characteristics of domestic black plum (Prunus domestica L.) genotypes grown in Iğdır

This study was carried out in order to determine the phenological, pomological and morphological characteristics of the black plum genotypes that grow naturally in Iğdır ecological conditions between the years of 2017-2018. In this study, 54 black plums genotypes were investigated and 15 genotypes were selected as promising between them according to weighted ratings method. Bud burst, first flowering, full flowering of examined black plum genotypes were ranged from 7-8 March, 14-23 March, 20-21 March, respectively and genotypes were harvested between 30 July and 10 August. In the investigated 54 genotypes, according to the 2-year averages fruit weight were between 37.77-80.31 g, fruit width 39.06-50.40 mm, fruit lenght 36.04-65.08 mm, fruit height 25.70-53.19 mm, seed weight 0.50-1.33 g, fruit flesh seed ratio-1 27.58-93.93 fruit volume 37-82 cm3, fruit density 0.79-1.38 g cm-3, fruit hardness 2.8-6.44 kg cm-2, titratable acidity 0.71-1.74%, total soluble solid 11.2-17.7% and pH 3.01-3.54. Fruit weight, fruit width, fruit lenght, fruit height, seed weight, fruit flesh seed ratio-1, fruit volume, fruit density, fruit hardness, titratable acidity, total soluble solid and pH in the 15 genotypes which were selected as promising according to weighted rating method were 56.69-80.31 g, 44.28-50.40 mm, 40.37-48.41 mm, 47.13-53.19 mm, 0.58-1.14 g, 60.87-99.87 52-82 cm3, 0.88-1.38 g cm-3, 3.32-5.66 kg cm-2, 0.83-1.44%, 11.90-15.60% and 3.02-3.27 respectively.
