Strawberry plant named `Idea`
A new and distinct variety of strawberry (species Fragaria) which is resistant to anthracnose (Colletotrcum actatium) is late ripening and has large conical berries with a bright orange-red color.
This new cultivar, named `Idea`, was selected in 1986 in a cultivated area in Cesena, Italy from the progeny of a cross made in 1984 between Sel 79.12.13 .times. `Etna`. The seed parent Sel 79.12.13 was a plant used only for its germplasm and was never released to the industry and is not the subject of a plant parent or application for a plant patent in the United States. The pollen parent `Etna` has been trialed at USDA, Beltsville, MD and at Whately, Mass. but never distinguished itself to be released in the United States and is not the subject of a plant patent or application for a plant patent in the United State. `Idea` has been asexually propagated by runner propagation, tissue culture and micropropagation. `Idea` has been asexually propagated in nurseries in Central Europe including Italy and in the United Kingdom and also in Massachusetts in the United States. `Idea` has been shown to be extremely stable in traditional plant propagation procedures for strawberries. There never has been a case reported of `Idea` not being stable is nurseries and fruit production trials.
The `Idea` variety id characteristically different from any other commercial variety in the United States today, including the California varieties. Its differentiating characteristics include its disease resistance, the lateness of fruiting, the berry color, and its large yield.
