Study biochemical traits of eight native apple cultivars in West Azerbaijan

In this study, the quantitative and qualitative characteristics of eight native apple varieties selected from the Azerbaijan area were evaluated. The studied varieties included 8 varieties consisting of Romina, Manochehri, Meshki, Torsh Alma, Sari Alma, Khan Almasi, Kozehee and local autumn that the varieties of Torsh Alma, Sari Alma and Khan Almasi were selected as the summer cultivars, and the varieties of local autumn, Romina, Manochehri, Meshki and Kozehee were selected as autumn cultivars. This experiment was carried out in Kahriz Horticultural Research station, Urmia in the form of completely randomized blocks design with three replications. The results of data variance analysis indicated the difference between varieties in terms of quantitative and qualitative studied traits, and revealed that the impact of variety on fruit total soluble solids (TSS), fruit pH, fruit ascorbic acid content (vitamin C), and fruit tissue firmness, fruit sugar and fruit juice is significant at 1% level. In the study, the varieties of Manochehri, Khan Almasi, Kozehee and Meshki had the highest content of total soluble solids (TSS), fruit sugar, ascorbic acid content, pH and fruit juice, and were in the superior statistical group. Also, the two cultivars of Khan Almasi and Torsh Alma had the highest tissue compared to other varieties.
