USPP5528P - Carnation named Londesty - Google Patents

Abstract

A new carnation cultivar particularly distinguished by the very light chartreuse yellow coloration of its blooms which are borne on long, strong, straight stems and which bloom profusely during the recurrent blooming seasons of Spring and Fall. This plant has a vigorous upright growth habit with moderately abundant foliage and a height averaging about 124 cm. at eight months, which provides rather extra long flower stems making it particularly advantageous for the cut flower market.

Description

BACKGROUND OF THE NEW PLANT

Our new carnation cultivar is the result of breeding efforts carried on by us at La Londe, Les Maures, France, since 1978, this new plant originating as a seedling produced from our crossing of selected and individually identified plants growing among our stock of plants maintained at La Londe for breeding purposes. This particular seedling was selected by us for propagation and test because of its very unusual flower color and its apparently very favorable growth habit. This discovery plant was reproduced by us at La Londe, by means of cuttings of the parent, and the result of that propagation effort appearing to be very favorable with respect to retention of the novel characteristics of its parent, we continued such propagation through several successive generations and established that the novel and distinctive characteristics of the discovery plant were fully retained from generation to generation and appeared to be firmly fixed.

DESCRIPTION OF THE DRAWING

Our new carnation cultivar is illustrated by the accompanying photographic drawing which has been hand painted to show the true flower color, a typical arrangement of buds and flowers in various stages of opening also being shown.

DESCRIPTION OF THE NEW PLANT

The following is a detailed description of our new carnation discovery based upon observations of greenhouse grown plants made 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.

Character.--Erect and rigid.

Color.--189A.

THE FLOWER

Blooming habit: Recurrent and profuse during midseason of Spring and Fall.

Size of bloom: Medium.

Diameter.--Averaging about 8.7 cm.

Depth.--Averaging about 6 cm.

Borne: Singly.

Shape:

When bloom first opens.--High centered.

When bloom matures.--Dome shaped.

Petalage:

Number of petals.--Averaging about 77.

Arrangement.--Imbricated.

Form.--Fan-shaped with finely serrated tip end edges.

Texture.--Soft.

Appearance.--Satiny.

Color.--Outer Petal: Body -- 2C and 155B. Reverse side -- 2 C and 2D. Inside Petal: Body -- 2C and 155B. Base -- Greenish Yellow. Reverse side -- 2C and 2D. All of the petals appear to be streaked with white.

Petaloids:

Number.--From zero to 6.

Size.--Smaller than the petals.

Color.--The same as the petals.

Flower stem:

Length.--About 78 cm. (cut at 10th node).

Character.--Upright with very good strength.

Color.--189A.

Fragrance: Absent or very light.

Persistence: The petals hang on and dry.

Lasting quality:

As cut flower.--At least 10 days with vase keeping.

Disease resistance: This variety appears to be resistant to Fusarium oxysporum as observed INRA, Antibes, Alpes-Maritimes, France.

REPRODUCTIVE ORGANS

Stamens:

Number.--3 To 8 arranged around the pistils.

Anthers.--Size: Less than 4 mm. Color: Whitish.

Filaments.--Color -- Whitish.

Pistils:

Number.--3 To 5.

Styles.--Color -- Yellowish White.

Stigmas.--Color -- Yellowish White.
