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

Abstract

The research carried out to evaluate 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), the lowest 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-2) obtained from BA29 followed by QA. In the cultivars, highest number of fruits (19.60 pieces tree-1), yield per tree (2.98 kg tree-1), yield per hectare (5685.00 kg ha-1) obtained from ‘Santa Maria’. In the research years, pre-harvest fruit drop rate (PHFDR 11.04%) and black spotted fruit rate (BSFR 13.79%) observed to be higher in 2021, while marketable fruit rate (MFR 77.03%) observed to be higher in 2020. In the rootstocks, the highest PHFDR (11.24%) observed on BA29 rootstocks, while highest MFR (73.72%) recorded on QA. In terms of cultivars, the highest PHFDR (10.73%) observed in ‘Williams’, while highest BSFR (16.41%) in ‘Deveci’, and highest MFR (76.31%) in the ‘Santa Maria’. As a conclusion, the highest yield and marketable fruit rate obtained from ‘Santa Maria’ cultivar and yield from BA29 rootstock. It could be suggested semi-dwarf cultivars and rootstocks for suitably performs under high density pear orchards.
