Quality Performance of Some Local Pear Cultivars on BA29 Rootstock under High Density Planting

The study aimed to assess the fruit quality characteristics of some local pears grafted on BA29 quince clone rootstock in 2021 and 2022. Pomological, chemical and sensory analyzes were carried out to evaluate fruit quality characteristics. All examined pomological properties were found to be statistically significant. The fruit weight (195.47 g), fruit width (73.56 mm), fruit height (73.72 mm), fruit stalk thickness (3.94 mm) and fruit volume (193.30 ml) of the ‘Karpuz’ pear were higher than the other cultivars. The highest fruit length (90.96 mm) and fruit stalk length (40.22 mm) in the ‘Eşek’ pear; the highest flesh firmness (9.35 kg cm-2) was determined in the ‘Harman’ pear. The total Soluble solid (TSS) content of the ‘Kara’ and ‘Rıza’ pears was higher (16.83% and 16.50%) than the other cultivars. In the color of the fruit skin; the highest L* value was determined in ‘Gelin’, a* value in the ‘Harman’, b* and chroma values in the ‘Karpuz’ and hue angle in the ‘Rıza’ cultivar. The highest L* value was in the ‘Harman’, a* value was in the ‘Kuşak’, b*, chroma and hue angle values were in the ‘Gelin’ pear in terms of fruit flesh color. While ‘Macar’, ‘Harman’ and ‘Eşek’ cultivars had the highest juiciness value, ‘Macar’ and ‘Kuşak’ had the lowest taste and aroma. The highest taste and aroma values were in the ‘Kadın PArmak’ pear; the best visual quality was determined in the ‘Eşek’ cultivar. The highest titratable acid content was observed from the ‘Rıza’ (0.60%). In the study, it was found that the ‘Karpuz’ had higher pomological properties. In general, ‘Karpuz’, ‘Eşek’, and ‘Gelin’ pears exhibited better quality performances in the study. According to the results of the research, ‘Karpuz’, ‘Eşek’ and ‘Gelin’ local cultivars can be recommended for more detailed evoluations. In addition, the local cultivars used in the research can be used as genetic resources.
