'Delicious' new grape debuts

24.03.2009
New muscadine grape for fresh fruit, wine markets

Researchers at the University of Florida have introduced 'Delicious', a new muscadine grape cultivar. 'Delicious' ripens early, produces high yields, and is disease-resistant.

The black fruit features exceptional taste and texture with an edible skin, making it well-suited for fresh fruit consumption and the potential for wine production. The name 'Delicious' was selected based on the comments of vineyard visitors who sampled the fruit.

According to Dr. Dennis J. Gray, who led the research study published in the February 2009 issue of HortScience, 'Delicious' (Vitis rotundifolia Michx.) originated from a cross between AA10-40, a self-fertile, bronze-fruited selection with medium-sized berries, and CD8-81, a self-fertile, black-fruited selection with larger berries. The researchers noted that black berry color of 'Delicious' likely originated from 'Southland' and the self-fertile trait came from 'Carlos', 'Southland', and/or 'Welder'. The original seedling was planted in 1993.

The berries of 'Delicious' are oval shaped and reddish, turning dark purple/black when ripe. Fruit ripening dates vary seasonally, but tend to occur in early August at Apopka, Florida, remarkably 2 to 3 weeks earlier than other muscadine cultivars evaluated. Early ripe fruit have a semicrunchy flesh and an edible skin. Fruit allowed to ripen further tend to have a softer flesh, become noticeably juicier, but retain an edible skin. The berries have a dry stem scar and harvest readily with mechanical shaking.

Although 'Delicious' is being released primarily as a fresh eating grape, it has some potential for wine. Based on preliminary trials, the flavor of the wine (2006 vintage) rated equal to those of 'Carlos' (a popular cultivar for wine) by a panel of 30 winemakers. The color is a medium to light red, generally lighter than many red muscadine wines.

Delicious' was publically released by the Cultivar Release Committee of the Florida Agricultural Experiment Station, an agricultural research program of the University of Florida's Institute of Food and Agricultural Sciences, in October 2007. Inquiries regarding the availability of 'Delicious' should be directed to Florida Foundation Seed Producers, Inc. P.O. Box 110200, Gainesville, FL 32611-0200.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...
