USPP5038P - Miniature rose plant -- Meiddanego variety - Google Patents

Abstract

A new and distinct variety of Miniature rose plant is provided which is a sport of Meirov variety. The new variety is identical to Meirov variety with the exception of the flower color which is of a distinctive bright blood red coloration. Such flowers are highly attractive and long lasting.

Description

SUMMARY OF THE INVENTION

The present new and distinct variety of Miniature rose plant resulted as a sport of the Meirov variety which is protected in a number of European countries by Breeder's Rights legislation, but is unpatented in the United States. Such Meirov parent variety has been marketed in Europe under the Meillandina trademark of the Universal Rose Selection Meilland et Cie. The parent Meirov variety possesses a different flower coloration than the present variety, but in all other respects is identical to the present variety. More specifically, the parent Meirov variety forms flowers of currant red with a canary yellow halo at the center. The present variety is distinguished from its parent by the formation of highly attractive flowers which are bright blood red in coloration.

The variety claimed herein is characterized as follows:

From the physical standpoint the plant has medium green adult wood and a bushy growth habit, and forms double flowers which are blood red in color wherein the petals are yellowish at the base and possess a great degree of substance; and

from the biological standpoint the plant has vigorous vegetation, is well adapted to hot culture, is resistant to disease, and has the ability to hold its flowers for a long period of time.

At the time of the filing of this application the present variety has not yet been protected in any country, nor has the present variety been placed on sale or used in a non-experimental manner in the United States.

Successive generations of asexual propagation by both cuttings and budding have shown that the new variety is stable and that the characteristics of this sport are uniformly passed from generation to generation.

The rose plant of the new variety has been named the Meidanego variety.

Length of bloom.--Very long.

Fragrance.--None.

Peduncle.--Straight, rigid, covered with a large number of small glands, length of approximately 2.6 to 3 cm.

Sepals.--Tomentose and greenish on the upperside, and light green sometimes with a touch of rouge and more or less glandular on the underside.

Bud.--Shape: globular at the opening of the sepals, then gradually changing to a cylindrical configuration. Size: average length of approximately 1.5 cm., medium size. Color: at the opening: upper surface: brilliant, Red Group 45A. Under surface: dull, Red Group 45B.

Bloom.--Size when fully open: averages approximately 4.6 cm. in diameter. Petalage: double, approximately 30 to 35 petals, have a great degree of substance, are rounded with apex forming a small point, base of petal on both sides is yellowish in color. Form: just as the sepals open the bud is somewhat flat with a sunken center and becomes fairly flat in form as the flower continues to open. Color: at the opening -- inside surface: blood red, Red Group, 45B. Outside surface: cherry red, Red Group 45C, and somewhat dull. Color: completely open -- inside surface: blood red, Red Group 45B. Outside surface: Cherry red, Red Group 45C. Color: end of bloom -- inside surface: blood red, somewhat lighter than Red Group 45B. Outside surface: blood red, Red Group 45D, dull. Stamens: on the average approximately 140 in number. Anthers: normal, yellow in color at the terminal end. Pistils: on the average approximately 48 in number.

Disease resistance: Good disease resistance.

Claims (1)

I claim:
