Carnation named Lontrelos

Abstract

A new spray carnation variety particularly distinguished by the very light Orient Pink coloration of its blossoms which are borne on straight, rather rigid peduncles branching from a rather rigid, upright stem having rather abundant foliage and a vigorous, upright growth habit which is rather resistant to Fusarium oxysporum.

Description

BACKGROUND OF THE NEW PLANT

Our new spray carnation is the result of breeding efforts carried on by us at La Londe, Les Maures, France, since 1973 with the object of developing a plant having nice color and good quality of flower stem and plant growth habit, and particularly resistant to Fusarium oxysporum. This new plant originated as a seedling produced by our crossing of selected and individually identified plants growing among stock of spray carnations maintained at La Londe for breeding purposes and this particular seedling was selected by us for propagation and test because of its very delicate pink coloration, its very favorable growth habit and its apparent resistance to Fusarium oxysporum. This discovery plant was produced by us at La Londe, by means of cuttings, with such a favorable result with respect to retention of the novel characteristics of its parent that we continued such propagation through several successive generations over a period of years and thereby determined that the novel and distinctive characteristics of the discovery plant weer fully retained from generation to generation and appeared to be firmly fixed.

DESCRIPTION OF THE DRAWING

Our new spray carnation is illustrated by the accompanying photographic drawing which shows, in full color, the upper portion of a typical flowering stem with buds and flowers in various stages of opening, the colors shown being as nearly true to those specified herein as is reasonably possible to obtain by conventional photographic procedures.

DESCRIPTION OF THE NEW PLANT

The following is a detailed description of our new spray carnation discovery based upon observations of greenhouse grown plants at La Londe, France, in the Spring of 1983, the color designations being specified according to The R.H.S. Colour Chart published by The Royal Horticultural Society of London, England.

This new variety of spray carnation most resembles "Silvery Pink" but differs from "Silvery Pink" by a more glaucous foliage, a stiffer stem, and a higher degree of earliness. In particular, the new variety is distinguished by its tolerance to Fusarium oxysporum.

Claims
