Abstract

The experiment was carried out to evaluate the performance of different apple cultivars during storage at Department of Horticulture, Agricultural University, Peshawar, Pakistan during 2007-08. The fruit of apple cultivars: Royal Gala, Mondial Gala, Golden Delicious and Red Delicious were harvested at commercial maturity and stored at 5±1°C with 60-70 % relative humidity. Physico-chemical changes in fruit were determined at 30 days interval during storage. Apple cultivar Red Delicious had the highest TSS/Acid ratio (23.12), fruit firmness (5.98 kg/cm2) and the least weight loss (2.22 %). Starch score was the maximum (5.22) in cultivar Golden Delicious. The percent weight loss, total soluble solids, pH and TSS/Acid ratio increased with increase in storage duration while starch score and firmness of fruit declined with increase in storage duration.
