Evaluation of internal quality of apple selections and cultivars bred in Holovousy

Evaluation of the internal quality parameters of new apple genotypes is an important step in selection and registration the new excellent cultivars. The overall taste of apples largely consists of the ratio of sweetness and acidity. Therefore, the soluble solid content, acidity, flesh firmness, and the pH value are most often monitored. In this study, parameters of internal quality in the new breeding selections HL 32, HL 1579, HL 2010, HL 1592, HL 2350, HL 53, HL 1304, and the cultivars ‘Julia’, ‘Judita’, ‘Rubinstep’, ‘Rucla’, ‘Reluga’, ‘Lady Silvia’, ‘Andera’, ‘Artiga’, ‘Fragrance’ and ‘Meteor’, that were bred in the Research and Breeding Institute of Pomology Holovousy Ltd., have been determined. Since the quality of apple genotypes varies from year to year depending on climatic conditions, the same apple cultivars were repeatedly harvested, and evaluated for consumer maturity in the years 2016, 2017, and 2018.
