Cultivars
There are over 300 muscadine cultivars growing in the southern states. These include bronze, black and red varieties and consist of common grapes and patented grapes.
Unlike most cultivated grapevines, many muscadine cultivars are pistillate, requiring a pollenizer to set fruit. A few, however, such as 'Carlos' and 'Noble', are perfect-flowered, produce fruit with their own pollen, and may also pollinate pistillate cultivars.
Cultivars include Black Beauty, Carlos, Cowart, Flowers, Fry, Granny Val, Ison, James, Jumbo, Magnolia, Memory (first found on T.S. Memory's farm in 1868 in Whiteville, NC), Mish, Nesbitt, Scuppernong, Summit, Supreme, Thomas, Produced by the University of Florida, the cultivar, 'Southern Home', contains both muscadine and subgenus Vitis in its background.
Crops can be started in 3–5 years. Commercial yields of 20–45 tonnes per hectare (8–18 tons per acre) are possible. Muscadines grow best in fertile sandy loam and alluvial soils. They grow wild in well-drained bottom lands that are not subject to extended drought or waterlogging. They are also resistant to pests and diseases, including Pierce's disease, which can destroy other grape species. Muscadine is one of the grape species most resistant to Phylloxera, an insect that can kill roots of grapevines.
