Carnation named Londorga

Abstract

A new variety of standard carnation distinguished by its profuse production of medium sized, dome shaped flowers of a very light overall color, the petals of which are striated with very thin red and white lines, the plant having a tall, vigorous, upright and rigid growth habit, an abundant production of foliage and a strong resistance to Fusarium oxysporum.

Description

BACKGROUND OF THE NEW PLANT

Our new standard carnation variety originated as a seedling at our breeding facilities at La Londe-Les-Maures-Var., France, and resulted from our crossing of two unnamed and unpatented varieties maintained in our breeding plant collection at La Londe. The object of this crossing was to produce an improved carnation plant having good quality and nice flower form and coloration suitable for commercial cut flower production. This particular seedling was selected by us for propagation and test because of the unusual color characteristics of its very light yellow blooms, and reproduction was done under our direction at La Londe by means of cuttings from the parent plant. Further propagation of this new variety at La Londe through several successive generations, by means of in vitro propagation and cuttings, has demonstrated that the novel characteristics of the parent seedling hold true from generation to generation and appear to be firmly fixed.

DESCRIPTION OF THE DRAWING

Our new carnation variety is illustrated by the accompanying full color photographic drawing which shows the inflorescence of a fully grown plant, the view including buds in various stages of opening, as well as fully opened flowers, the color rendition being as nearly true as is reasonably possible to obtain by means of conventional photographic procedures from subjects of such a light yellow coloration.

DESCRIPTION OF THE NEW PLANT

The following is a detailed description of our new carnation cultivar based upon observation of plants growing under conventional procedures at La Londe-Les-Maures-Var., France, the color designations being according to The R.H.S. Colour Chart published by The Royal Horticultural Society of London, England.

This new carnation most resembles the variety "Alice" (unpatented). Compared with "Alice", however, this new variety of carnation has a bigger flower and a longer stem. Also, the new variety is more resistant than "Alice" to Fusarium oxysporum.

Claims

1. A new and distinctive carnation variety, substantially as herein shown and described, characterized by its high productivity of very light yellow flowers of medium size having fan-shaped petals with thin striae of red and white.
