USPP7301P - Spray carnation named Lonchezu - Google Patents

Abstract

A new spray carnation cultivar particularly distinguished by its relatively small, primrose yellow flowers having clean, unblemished petals regularly imbricated to provide a pleasing, well formed flower, which is produced profusely during the Spring, midseason and Fall blooming periods on a strong, vigorous plant having an average height of about 105 cm. and which has abundant foliage and good resistance to Fusarium oxysporum.

Description

BACKGROUND OF THE NEW PLANT

This new spray carnation plant originated as a seedling of a hybrid developed by us at our nursery at 83250 La Londe-Les-Maures, France, by our crossing two selected carnation varieties from our collection maintained for breeding purposes at our nursery at La Londe, the selected breeding varieties being unnamed and unpatented. This particular seedling of the said hybrid was chosen for propagation because of its clear, bright yellow flowers which the plant produced profusely with a vigorous, upright growth habit. This selected seedling was propagated from cuttings under our direction at La Londe with very satisfactory results, which prompted us to direct continued propagation at our nursery through several successive generations both by cuttings and by in vitro propagation procedures, thereby establishing that the distinctive features of the new plant would be retained from generation to generation and assuring its homogeneity. Present propagation of this new plant is being done at 83250 La Londe-Les-Maures, France.

DESCRIPTION OF THE DRAWING

This new carnation cultivar is illustrated by the accompanying photographic drawing, which shows stems of the new variety with buds and blooms in several stages of development, the colors shown being as close to those herein specified as is reasonably possible to obtain by conventional, professional photographic procedures.

DESCRIPTION OF THE NEW PLANT

The following is a detailed description of our new spray carnation cultivar based upon our observations during the Spring of the current year of plants grown in southern France, the color designations being according to The R.H.S. Colour Chart published by The Royal Horticultural Society of London, England.

THE FLOWER

Blooming habit: Recurrent and profusely during Spring, midseason and Fall blooming periods.

Size of flower: Small.

Diameter.--Averages about 5.6 cm.

Depth.--Averages about 4.2 cm.

Shape: When bloom first opens, high-centered. When bloom matures, dome-shaped.

Petalage:

Number of petals.--About forty-seven, in average.

Arrangement.--Imbricated.

Form.--Fan-shaped with rounded edges and a very little serration at the apex.

Texture.--Leathery.

Aspect.--Satiny.

Color.--Outer petals: Body -- Primrose Yellow 4-B. Base -- Greenish white. Reverse side -- 4-B. Inside petals: The same as the outer petals.

Petaloids.--Number: Less than six. Size: Smaller than the petals. Color: The same as the petals.

Flower stem:

Length.--Averages about 68.5 cm. when cut at the tenth node.

Color.--189-A.

Character.--Upright with good strength.

Discoloration after full bloom: Very little.

Fragrance: Perceptible.

Persistence: The flowers hang on and dry.

Disease resistance: Resistant to Fusarium oxysporum as observed I.N.R.A. 06600 Antibes, France.

Lasting quality: At least ten days as a cut flower in vase keeping.

REPRODUCTIVE ORGANS

Stamens:

Number.--About twelve to eighteen.

Arrangement.--Encircling the ovary.

Anthers.--Size: About 4 mm. Color: Whitish.

Filaments.--Length: Averages about 1.6 cm. Color: Whitish.

Pistils:

Styles.--Length: About 2.9 cm. Color: Yellowish.

Stigma.--Color: Yellowish.

Characteristics of ovaries: Ribbed.

The present variety most nearly resembles the variety `Londragel` (U.S. Plant Pat. No. 6,571) but differs materially by having a longer stem and its flowers never show red markings.

The characteristics of the above described variety may be more-or-less modulated when grown under various environmental conditions, such as the nature of the ground, method of cultivation and latitude, as observed of plants grown in Spring in southern France.
