Adaptability of introduced varieties of blueberry (Vaccinium Uliginosum L.) plant to climate conditions of Tashkent Province, Uzbekistan

Abstract

The article meticulously outlines the outcomes of a detailed scientific study aimed at evaluating the adaptability of various blueberry varieties within the central climatic conditions of Uzbekistan, focusing particularly on their growth patterns and productivity levels. The investigation, set against the backdrop of the Tashkent province's unique environmental parameters, provides invaluable insights into the cultivation potential of blueberries, a crop not traditionally associated with the agronomic landscape of Uzbekistan. A key finding of this research is the determination of the vegetation period for the introduced blueberry varieties, which spanned between 213 to 221 days. The study further categorizes the introduced blueberry varieties into three distinct ripening groups: early, medium, and late. This classification not only aids in the strategic planning of harvest schedules to ensure a continuous supply of blueberries throughout the season but also highlights the genetic diversity and adaptability of these varieties to the climatic conditions of the Tashkent province. Among the varieties studied, 'Duke' and 'Bluecrop' were identified as the highest-yielding, marking them as particularly suitable for extensive cultivation in the region due to their productivity and potential economic benefits. On the other end of the spectrum, the 'Aurora' variety was noted for its lower productivity, although it could still contribute to biodiversity and the extension of the harvesting season. The remaining varieties were classified as having average productivity, offering a balanced option for cultivators seeking to diversify their blueberry crops.
