Phenological, Morphological and Pomological Characteristics of 'Samsun Güzeli' Pear Genotype on Ba29 Rootstock

Abstract

T & uuml;rkiye has many local pear cultivars; some of them do not have much production and propagation potential due to their low quality and undesirable vegetative and generative characteristics. However, those that are superior in terms of fruit quality and yield characteristics have found a place for themselves in both local and national markets. In this respect, the 'Samsun G & uuml;zeli' genotype, which is an important local cultivar, is an ideal cultivar with many features and has a high potential to spread its cultivation all over T & uuml;rkiye and other countries. 'Samsun G & uuml;zeli' is an autumn genotype, can easily meet the high demand in local and international markets due to its attractive color, smooth fruit shape and high quality. Despite all these valuable features, this cultivar is still not well known in T & uuml;rkiye. There is a great need to disseminate cultivation and research on this subject. This study mainly aimed to reveal the phenological, morphological and pomological characteristics of the 'Samsun G & uuml;zeli' local pear genotype grafted on BA29, a commercially traded rootstock in 2021-2022. The results showed that the 'Samsun G & uuml;zeli' pear genotype completed its phenological cycle in 255 days in 2021 and 228 days in 2022 in Samsun climatic conditions. Fruit set rate of the genotype was 12.05% and the average yield was 17306.23 kg ha-1. It was also determined that the morphological characteristics averages were as the following; rootstock diameter 76.71 m(3), annual shoot length 37.19 cm and leaf area 11.74 cm(2). Averages values of pomological and chemical properties recorded as the following; fruit weight 114.60 g, fruit volume 109.90 ml, soluble solid content (SSC) 13.16%, acidity 0.33%, and pH 4.37. In the sensory evaluations, the highest scores were obtained by juiciness (6.32) in the year 2022 while scores of overall visual quality were lowest in both years. In conclusion, it can be said that the 'Samsun G & uuml;zeli' genotype performs adequately in terms of fruit yield and quality on the standard dwarf rootstock and conducting new studies might be beneficial to disseminate the genotype.
