Study and Evaluation of Quality Indicators of Raceme Tomato Hybrids Under Greenhouse Conditions

2024

The increased demand for tomato products has spurred the cultivation of various varieties and hybrids. Particularly notable are the tomato hybrids whose fruits are harvested collectively in entire branches (racemes), thus earning them the name “raceme tomatoes”. The scientific studies were carried out in 2021-2023, in the glass experimental greenhouse of the Scientific Center of Vegetable and Industrial Crops of the Ministry of Agriculture of the RA, Darakert, Ararat Marz, during two vegetation periods: spring and autumn. The study focused on five raceme tomato hybrids: Prodezo F1, Santiana F1, Adventure F1 by Rijk Zwaan, Climbo F1 by Syngenta, and hybrid RM-4, which was obtained by us (Known since 2023 as Syune). Prodezo F1 hybrid, which is included in the state register of Armenia, served as the control. The selection of hybrids was based on the increasing demand among the population for raceme tomatoes. According to varietal characteristics and vegetation period, the dry matter content varied from 6.14 % to 7.74 %, which was 2.88 % - 3.22 % for sugars, and 18.44 % - 22.13 % for ascorbic acid content. As a result of the study, the hybrids Adventure F1 by Rijk Zwaan and RM-4 (Syune), a locally cultivated hybrid, stood out for their quality indicators among the examined tomato hybrids, regardless of the vegetation period. These high-quality hybrids will be introduced to greenhouses of Armenia for further cultivation.
