CULTIVAR SELECTION FOR DRIED QUINCE PRODUCTION BASED ON PROCESSING PERFORMANCE AND QUALITY PRIORITIES

This study presents a descriptive secondary analysis of cultivar-level data reported for seven quince cultivars during 2023–2025. Its objective was to distinguish cultivars suited to processing output from those suited to quality preservation under a common pretreatment and combined drying regime. Reported drying duration, dried product yield, vitamin C retention, overall sensory score and relative energy saving were compared. A yield-to-time index was calculated, and a Pareto comparison identified alternatives that could not be improved across all selected criteria simultaneously. Dessertnaya had the highest yield-to-time index, 2.02 percentage points of yield per drying hour, compared with 1.63 for Toshkent yumaloq behi. Samarqand yirik mevasi provided the highest reported vitamin C retention, 88.0%, while Samarqand yirik mevasi and Qoqon behi shared an overall sensory score of 4.73. Dessertnaya, Samarqand yirik mevasi and Qoqon behi formed the nondominated set. These findings support production-oriented cultivar selection rather than a universal recommendation. Because only aggregate values were available, the comparisons are descriptive and do not establish statistical significance or independently validate the underlying experiments.
