Carnation named Lonseva

Abstract

A new carnation cultivar distinguished by its profuse production of light pink, medium sized blooms carried on long, stiff stems, its vigorous, upright growth habit with moderately abundant foliage, and by its resistance to Fusarium oxysporum.

Description

BACKGROUND OF THE NEW PLANT

This new carnation variety was developed by us at our production facilities at La Londe-Les Maures-Var, France, as a seedling resulting from the cross of two unnamed and unpatented carnation varieties maintained in our collection for breeding purposes. This seedling was selected for propagation and test because of its apparently vigorous growth habit and its beautiful light pink bloom of medium size. The object of this crossing was to produce a strong plant, the flowers of which would have a very attractive form and coloration carried on long, strong stems, and at the same time, have a good resistance to Fusarium oxysporum. Reproduction of this seedling was done at La Londe by means of cuttings and successive generations of this plant have demonstrated that the novel characteristics of the parent are retained from generation to generation and appear to be firmly fixed.

DESCRIPTION OF THE DRAWINGS

Our new variety of carnation plant is illustrated by the accompanying photographic drawings which show the color characteristics of the flower as nearly true as it is reasonably possible to obtain by conventional commercial photographic procedures, the view showing buds in several stages of opening, as well as fully developed flowers.

This new carnation cultivar most nearly resembles the variety "Baranna" (U.S. Plant Pat. No. 3,534) and compared with "Baranna" and "Barlo II" (U.S. Plant Pat. No. 3,406), the blossom of the new plant has rather deeply serrated petals, a stiffer stem, and an intermediate color. Also, this new variety is more tolerant to Fusarium oxysporum than the others referred to.

Claims

1. A new and distinct carnation cultivar, substantially as herein shown and described, characterized in particular by its light pink, medium sized blooms of full shape carried on rather long, stiff stems.
