Evaluation of Quality Characteristics and Cultivar Candidate Potentials of Hybrid Genotypes Obtained from Different Vitis Species

Table grape breeding programmes are ongoing in different countries to develop new grape cultivars suitable for rapidly changing consumer demands. Although Türkiye is among the world’s leading countries in table grape production, it does not have quality grape cultivars that can compete in foreign markets. Different breeding programmes are conducted in the country to develop new quality table grape cultivars. These breeding studies’ primary goals are to achieve table grapes that are seedless, with crispy flesh, a large berry size, unique aromas, higher phenolic contents, and improved disease resistance. This study evaluated the basic quality characteristics of 89 hybrid genotypes with different parents obtained from crossbreeding studies and passing the preliminary screening stage. The hybrid genotypes were evaluated comprehensively for many quality criteria. In particular, the hybrid genotypes that received the desired score according to tasting panel results were determined. Among these, genotypes 22BY-097, 14KS-03, 18BK-02, and 22BY-044, which are seedless and have different parents, were the highest-scoring hybrid genotypes, due to their different superior characteristics. High-scoring hybrid genotypes will be registered after these quality characteristics are evaluated in different locations in the next stage. Consequently, the accuracy and consistency of the results obtained will be confirmed, and new cultivars will be transferred to table grape growers in the future. With these high-quality new cultivars, table grape growers can earn more income.
