CULTIVATION AND YIELD PERFORMANCE OF NEW RASPBERRY CULTIVARS

This article presents the findings of a study on the introduction and cultivation of new raspberry cultivars under the meadow-bog soil conditions of Andijan Region. Field observations were conducted during 2025–2026 and followed cultivar establishment and phenological development, including emergence, vegetative growth, flowering and the onset of fruit ripening. The first flowers were observed on 5 May 2026. The earliest fruit ripening began in Lyachka on 2 June, while Maravilla and Mapema began ripening on 25 June. Vajolet began to ripen on 28 September, as reported in the study. Observations also indicated differences in adaptation to high summer temperatures: cultivars developed in Italy, the United States and the Netherlands performed more favourably than the Russian cultivars Augustina and Vladimir under the conditions observed. On this basis, Maravilla, Margarita, Vajolet and Mapema are recommended for further cultivation in Andijan Region. Since the evidence comes from one experimental site and one observation season, the conclusions should be interpreted within that scope.
