Effects of Quince Rootstocks and Pear Cultivars on Fruit and Yield Characteristics

Abstract

The research carried out to evaluate the effects of quince rootstocks [Quince Province BA29 (BA29), Quince A (QA), Quince C (MC)], pear cultivars, and research years on fruit quality and yield efficiency in the years 2020-2021. The highest fruit weight was obtained from BA29 (196.02 g), and the lowest was from MC (158.09 g). In the cultivars, the highest fruit weight was obtained from ‘Abate Fetel’ (210.85 g), the lowest from Santa Maria (156.73 g). The highest number of fruits (17.06 pieces tree-1), yield per tree (3.13 kg tree-1), yield per hectare (5982.8 kg ha-1), and yield per trunk cross sectional area (0.30 kg cm-1) obtained from BA29 followed by QA. In the cultivars, the highest number of fruits (19.60 pieces tree-1), yield per tree (2.98 kg tree-1), and yield per hectare (5685.00 kg ha-1) were obtained from ‘Santa Maria’. In the research years, the pre-harvest fruit drop rate (PHFDR 11.04%) and black spotted fruit rate (BSFR 13.79%) were observed to be higher in 2021, while the marketable fruit rate (MFR 77.03%) was observed to be higher in 2020. In the rootstocks, the highest PHFDR (11.24%) was observed on BA29 rootstocks, while the highest MFR (73.72%) was recorded on QA. In terms of cultivars, the highest PHFDR (10.73%) was observed in ‘Williams’, while the highest BSFR (16.41%) was in ‘Deveci’, and the highest MFR (76.31%) in ‘Santa Maria’. As a conclusion, the highest yield and marketable fruit rate were obtained from the ‘Santa Maria’ cultivar and yield from BA29 rootstock. It could be suggested that semi-dwarf cultivars and rootstocks for suitably perform under high density pear orchards. © 2023, Centenary University. All rights reserved.
