Outline:
Muscadine grape (vitis rotundifolia), a native species of the southeastern United States, is one of the major fruit crops growing in Florida. It is more disease resistant to several diseases, including Pierce’s disease, than any other bunch grapes and very productive. However, the fruit suffers from extensive economic losses every year due to fruit berry rot diseases. These fruit berry rot diseases include: Black Rot (Guignardia bidwellii), Bitter Rot (Greeneria uvicola), Macrophoma Rot (Botryosphaeria dothidea), and Ripe Rot (Colletotrichum sp.). Black rot is the most destructive fruit rot disease in muscadine grape. The objective of this project would be to screen the black rot disease in 45 commercially-available muscadine grape cultivars in the vineyard at the Center for Viticulture and Small Fruit Research of Florida A&M University, to identify promising mucadine grape germplasm for use as parents in the breeding and genetics research program, and to make cultivar selection decisions for grape growers. To do this, five clusters will be randomly selected and scored based on the number berries with black rot. Percentage of diseased berries will be calculated based on the total berries and results will be analysized for black rot severity.
Key Words: Muscadine, Fruit Black Rot Disease, Disease resistant, Macrophoma Rot, Bitter Rot, Black Rot
