'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: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
