USPP9001P - Hybrid Tea rose plant named Meinivoz - Google Patents

Abstract

A new and distinct variety of Hybrid Tea rose plant is provided which abundantly and continuously forms attractive very double yellow blossoms. The blossoms are very fragrant and are Amber Yellow in coloration. Such blossoms are long lasting and their petals drop off cleanly. The plant exhibits an upright growth habit, very vigorous vegetation, Bronze Green adult wood, and is particularly well suited for growing in parks and gardens. Also, the new variety is not particularly affected by cryptogamic diseases.

Description

SUMMARY OF THE INVENTION

The new variety of Hybrid Tea rose plant was created by artificial pollination wherein two parents were crossed which previously had been studied in the hope that they would contribute the desired characteristics. The female parent (i.e., the seed parent) of the new variety was the product of the crossing of the Meitulandi variety (non-patented in the United States) and the Mischief variety (non-patented in the United States), and the male parent (i.e., the pollen parent) was the Meinuzeten variety (U.S. Plant Pat. No. 4,224). The Meitulandi variety sometimes is known as the Hidalgo variety. The parentage of the new variety can be summarized as folows:

(Meitulandi×Mischief)×Meinuzeten.

The seeds resulting from the above pollination were sown and 52 small plants were obtained which were physically and biologically different from each other. Selective study resulted in the identification of a single plant of the new variety.

It was found that the new variety of Hybrid Tea rose plant of the present invention possesses the following combination of characteristics:

(a) forms in abundance on a continuous basis attractive long-lasting very double fragrant flowers which are Amber Yellow in coloration,

(b) exhibits an upright growth habit,

(c) exhibts very vigorous vegetation,

(d) exhibits Bronze Green adult wood, and

(e) is not particularly affected by cryptogamic diseases.

The petal drop capability of the blooms following flowering is good.

The new variety well meets the needle of the horticultural industry for a number of uses and is particularly well suited for growing as attractive ornamentation in parks and gardens.

The new variety has been found to undergo asexual propagation in France and in the United States by a number of routes, including budding, grafting, and cuttage. The characteristics of the new variety have been found to be strictly transmissible by such asexual propagation from one generation to another.

The new variety has been named the Meinivoz variety.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph shows as nearly true as it is reasonably possible to make the same, in a color illustration of this character, typical specimens of the plant parts of the new variety. The rose plants of the new variety were two years of age and were observed during September while budded on Rosa froebelii understock and growing outdoors at LeCannet des Maures, Var, France.

DETAILED DESCRIPTION

The chart used in the identification of the colors is that of The Royal Horticultural Society (R.H.S. Colour Chart). The description is based on the observation of two-year old plants made during September while budded on Rosa froebelii understock and growing outdoors at LeCannet des Maures, Var France. The coloration in common terms precedes reference to the chart.

Class: Hybrid Tea.

Plant:

Height.--Approximately 1.2 to 1.3 m. When grown outdoors after one growing season at Wasco, Calif., U.S.A., a mature two-year old plant commonly assumes a height of approximately 1.5 to 1.6 m. Stem lengths of approximately 50 cm. commonly are formed in the springtime when the plant is grown outdoors at Wasco, Calif. U.S.A.

Habit.--Upright.

Branches:

Color.--Young stems: medium green, Yellow-Green Group 146B, and more or less tinted with reddish coloration. Adult wood: Bronze Green, Yellow-Green Group 146A.

Thorns.--Size medium. Quantity: Moderately numerous. Color: Greenish on young stems and light tan on adult wood.

Leaves:

Stipules.--Adnate, pectinate, very wide, linear, and edged with pediculate glands.

Petioles.--Upper surface: striped reddish green on young foliage and medium green on mature foliage with more or less glandular edges. Under surface: light green, and rarely bears a few prickles.

Leaflets.--Number: 3, 5, and 7. Shape: oval. Serration: single and regular. Texture: consistent. General appearance: Matte, dense foliage. Color (young foliage): upper surface: Medium green, Yellow-Green Group 146B. under surface: light green, Yellow-Green Group 147C, and more or less suffused with reddish coloration. Color (adult foliage): upper surface: Bronze Green, Yellow-Green Group 146A. under surface: light green, Yellow-Green Group 146C.

Inflorescence:

Number of flowers.--Usually a single bloom per stem.

Peduncle.--Light green and smooth. The length is approximately 6 to 8 cm. on average.

Sepals.--Upper surface: tomentose, greenish, and more or less stained with reddish coloration. Under surface: light green in coloration, the outer sepals have glandular slightly appendiculated edges, and terminate in a small leaf-like appendix.

Buds.--Shape: ovoid. Length: approximately 3 cm. on average. Size: large. Color upon opening: upper surface: Amber Yellow, Yellow-Orange Group 18C. under surface: Amber Yellow, Yellow-Orange Group 18C, suffused with Chinese Coral, Orange-Red Group 32D.
