Rose plant--Meixapic variety

Abstract

A new and distinct variety of Hybrid Tea rose plant is provided which abundantly forms attractive fully double blossoms which are dawn pink on the upper surface and Venetian pink on the under surface. Such blossoms are very long lasting whether left on the plant or present in a vase. The plant exhibits an upright growth habit, semi-dull vigorous vegetation, and is well suited for growing as ornamentation in parks and gardens. Additionally, the plant is not particularly affected by cryptogamic diseases.

Description

SUMMARY OF THE INVENTION

The new variety of Hybrid Tea rose plant was discovered as a bud mutation of unknown causation of the Meikruza variety (U.S. Plant Pat. No. 5,864) which exhibits a distinctive blossom coloration. The blossoms of the new variety are of the same configuration as the parent variety and unlike the parent variety are dawn pink on the upper surface and Venetian pink on the under surface. The blossoms of the parent variety are light Indian yellow widely suffused with light salmon pink.

The new variety has been carefully studied and its distinctiveness with respect to blossom coloration has been confirmed. Had the new variety not been discovered and preserved it would have been lost to mankind.

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 attractive very long lasting fully double blossoms which are dawn pink on the upper surface and Venetian pink on the under surface,

(b) exhibits an upright growth habit,

(c) exhibits vigorous vegetation,

(d) is particularly suited for growing in parks and gardens, and

(e) exhibits very good disease resistance.

The blossoms last a very long time whether cut or on the plant. Also, the blossom petals drop off cleanly.

The new variety well meets the needs of the horticultural industry for all 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 by a number of routes, including budding, grafting, cuttings, etc. 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 Meixapic 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 November while budded on Rosa indicia understock and growing in greenhouses at Cap d'Antibes, 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 November while budded on Rosa indicia understock and growing in greenhouses at Cap d'Antibes, France. The coloration in common terms precedes reference to the chart.

Class: Hybrid Tea.

Plant:

Height.--Plants which were pruned to a height of 85 cm. produce floral stems having a length of approximately 30 to 75 cm. When grown in fields at Wasco, Calif., the plant commonly is approximately 1.5 m. in height at the end of the growing season.

Habit.--Upright.

Branches:

Color.--Young stems: bronze green, Yellow-Green Group 146B, widely tinted with reddish brown. Adult wood: bronze green, Yellow-Green Group 146B.

Thorns.--Size: medium. Quantity: average. Color: pinkish on young stems and pinkish green changing to tan on mature wood.

Leaves:

Stipules.--Adnate, pectinate, fairly large and linear.

Petioles.--Upper surface: striped reddish brown on young foliage and medium green on adult foliage with more or less glandular edges. Under surface: bright green, more or less shaded with reddish brown, bear a few small prickles.

Leaflets.--Number: 3, 5 (rarely), and 7 (most often). Shape: elliptic generally wide and symmetrical, commonly have a rounded and asymmetrical base. Serration: single and regular. Texture: leathery. General appearance: foliage is somewhat dense, ample and semi-dull. Color (young foliage): Upper surface: reddish brown. Under surface: reddish brown.

Inflorescence:

Number of flowers.--Generally one per stem.

Peduncle.--Straight, rigid, and smooth. The length is approximately 8 cm. on average.
