The sultana is a "white", oval seedless grape variety also called the sultanina, Thompson Seedless, Lady de Coverly (England), and oval-fruited Kishmish. It is also known as İzmir üzümü in Turkey since this variety has been extensively grown in the region around İzmir. It is assumed to originate from Asia Minor, which later became part of the Ottoman Empire.

A grape is a fruit, botanically a berry, of the deciduous woody vines of the flowering plant genus Vitis. Grapes are a non-climacteric type of fruit, generally occurring in clusters.
