Rose plant--Meinuzeten variety

Abstract

A rose plant of the Hybrid Tea Class is provided having double flowers which are Saturn red on the inside and ochre yellow on the outside. The seed parent of the new variety resulted from the pollenation of a seedling obtained by the fertilization of the variety MEIalfi by the variety Meifan 00186F with pollen from the variety King's Ransom. The pollen parent of the new variety was the variety Whisky Mac.

Description

SUMMARY OF THE INVENTION

The object of the present invention is to provide a new variety of rose-plant of the Hybrid Tea Class having double flowers which is distinguished from prior varieties by the following characteristics:

(1) particularly elegant slightly perfumed flowers which are Saturn red on the inside, and ochre yellow on the outside, and

(2) a bush growth habit which exhibits staged blossoming which is rapidly remontant.

In view of these characteristics the new variety meets the needs of the horticultural industry and is particularly suited for ornamental use in parks and gardens.

The seed parent of the new variety resulted from the pollenation of a seedling obtained by the fertilization of the variety MEIalfi by the variety Meifan 00186F with pollen from the variety King's Ransom (U.S. Plant Pat. No. 2103). The pollen parent of the new variety was the variety Whisky Mac.

This parentage of the new variety may be expressed as follows:

[(MEIalfi .times. Meifan 00186F) .times. KING'S RANSOM] .times. WHISKY MAC

the seeds resulting from the above pollenation were sown and 525 plantlets were obtained which were physically and biologically different from each other. Selective study resulted in the identification and preservation of the new variety. Extensive testing has confirmed the behavior and productivity of the new variety.

The characteristics and properties of this new variety, obtained as indicated above are strictly transmissible by agamic means, also called "asexual", i.e., by means of vegetative propagation, in particular by grafting an eye. The rose-plant of the new variety has been designated the Meinuzeten variety.

DETAILED DESCRIPTION OF THE DISCLOSURE

The plant described was grown in the open air in Cannet-des-Maures, Var, France.

The chart used in the identification of the colors is that of the Royal Horticultural Society (R.H.S. Color Chart). The terminology preceding the numbered references proper to this chart, has been added to designate, in common terms, the corresponding colors.

Class: Tea hybrid.

Plant:

Height.--1.30 to 1.40 meters.

Habit.--Bush.

Branches:

Color.--Young stems: light green 146/B (yellow green group) broadly shaded with reddish coloration. Mature wood: bronze green 164/A (yellow green group).

Thorns.--Shape: Upper edge: straight. Lower edge: concave. Size: rather large. Quantity: average. Color -- on young stems: reddish. On mature wood: greenish pink, then havana brown (common terms).

Leaves:

Stipules.--Adnate, pectinated, broad and linear.

Petiole.--Obverse: grooved -- reddish brown on young foliage, medium green on mature foliage -- more or less glandular. Reverse: reddish brown on young foliage, light green on mature foliage, carries some small hooked thorns.

Folioles.--Number: most often 3 and 5, also 7. Shape: oval, cordiform base, pointed tip. Denticulation: simple and regular. Texture: coriaceous. General effect: rather ample and dense foliate, half-mat aspect. Color -- young foliage: Obverse: dark green 147/A (yellow green group) more or less spotted with reddish coloration. Reverse: light green 147/C (yellow green group) more or less spotted with reddish coloration. Adult foliage: Obverse: dark green 147/A (yellow green group). Reverse: light green 147/C (yellow green group).

INFLORESCENCE

number of flowers.--Generally one flower per stem.

Peduncle.--Straight, rigid, generally smooth, broadly spotted with brown-reddish coloration. Length: 6.5 cm.

Sepals.--Obverse: tomentose, greenish more or less spotted with reddish coloration; Reverse: light green more or less spotted with reddish coloration. The sepals on the outside have their edges broadly appendiculate and slightly glandular.

Bud.--Shape: conical. Length: 3.5 cm. Size: large. Color. -- on opening: Obverse: Saturn red 30/B (orange red group) toward the center, capsic red 33/A (orange red group) on the edges. Reverse: Ochre yellow 22/A (yellow orange group) broadly spotted with carmine coloration on the edges.

Flower.--Form: first as full cup, then opens into hollow cup with stamens apparent, double flower. Diameter: 10.5 cm. on the average. Color -- at the opening. Obverse: Saturn red 30/C (orange red group) toward the center and fire red 33/B (orange red group) on the edges.
