Abstract: Fifteen different grape varieties were evaluated for raisin making and raisin quality. The highest raisin recovery was observed in Clone 2A as compared to other varieties in this study. Amongst the different varieties, TSS ranged from 22.30 °B in AH-2-8 to Manjari Kishmish and Clone 2A with 23.60 °B TSS. The highest reducing sugar content in fresh berries and raisins was recorded in the Rieber variety. The highest protein content in fresh berries and raisin was recorded in Sundekhani and Merbein Seeded. However, the highest phenol concentration was found in Manjari Kishmish and Convert Large Black. The maximum carbohydrate was higher in Red Muscat and Athens. The variety Clone 2A was found better for higher raisin recovery and can be a potential variety in grape growing regions for raisin purposes.
