Hybrid tea rose plant named ‘Meileyet’

Abstract

A new and distinct variety of Hybrid Tea rose plant is provided which forms attractive double blossoms that are pale pink bordered with pink depending on the season. Such blossoms possess no fragrance. The plant exhibits an erect growth habit, dark green and semi-glossy foliage, and very good disease resistance. The new variety is particularly well suited for producing cut flowers under greenhouse growing conditions.

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 ‘Tanselbon’ variety (non-patented in the United States). The male parent (i.e., the pollen parent) was the product of the cross of the ‘Erotika’ variety (non-patented in the United States) and the ‘Devolor’ variety (non-patented in the United States). The parentage of the new variety can be summarized as follows:

‘Tanselbon’×(‘Erotika’בDevolor’).

The seeds resulting from the above pollination were sown and 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) Is substantially free of thorns,

(b) Forms attractive double blossoms that are pale pink bordered with pink depending on the season,

(c) Exhibits an erect growth habit, and

(d) Is particularly well suited for the production of cut flowers under greenhouse growing conditions.

The new variety well meets the needs of the horticultural industry and exhibits good productivity during cut flower production in a greenhouse.

The new variety has been found to undergo asexual propagation in France by a number of routes, including budding, grafting, and cuttage. Asexual propagation by the above-mentioned techniques in France has shown that the characteristics of the new variety are stable and are strictly transmissible by such asexual propagation from one generation to another.

The new variety has been named the ‘Meileyet’ 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 April while budded on Rosa indica understock and growing in greenhouses at Le Cannet des Maures, Var, France. Dimensions in centimeters are indicated at the bottom of the photograph.

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 during April while budded on Rosa indica understock and growing indoors at Le Cannet des Maures, Var, France. The coloration in common terms precedes reference to the chart in some instances.

Class: Hybrid tea.

Plant:

Height.—When pruned to a height of 85 cm., floral stems of approximately 60 to 80 cm. in length commonly are produced.

Habit.—Erect.

Branches:

Color.—Young stems: near Green Group 137D. Adult wood: near Green Group 137C.

Thorns.—Size: medium when present. Quantity: very few, is substantially free of thorns. Color: greenish. Configuration: fairly straight and fringed on the upper surface and slightly curved on the under surface.

Leaves:

Stipules.—Adnate, pectinate, and narrow.

Petioles.—Upper surface: slightly glandular, and medium green in coloration. Under surface: commonly with a few prickles and light green (near Green Group 137A) in coloration suffused with anthocyanin coloration.

Leaflets.—Number: 3, 5 (most often), and 7. Shape: with a symmetrical tip. Serration: regular (as illustrated). Texture: normal. General appearance: fairly dense, medium green, and semi-glossy. Color (young foliage): Upper surface: near Green Group 137A with some reddish staining. Under surface: near Greyed-Green Group 191A with some reddish staining.
