Hybrid tea rose plant named ‘WEKrigoyelo’

Abstract

A new variety of Hybrid Tea rose suitable for garden decoration, having flowers of vibrant pink with a golden glow coloration.

Description

Classification: The present invention relates to a new Rosa hybrida plant.

Variety denomination: The new plant has the varietal denomination ‘WEKrigoyelo’.

BACKGROUND OF THE INVENTION

This invention relates to a new and distinct variety of Hybrid Tea Rose. It has as its seed parent the variety known as ‘DORviso’ (not patented) and has an undisseminated seedling of my creation as its pollen parent with the following genetic origin SeedlingבO Sole Mio’.

SUMMARY OF THE INVENTION

Among the features which distinguish the new variety from other presently available and commercial rose cultivars known to the inventor are the following combination of characteristics: its peduncle bearing long prickle-like stipitate glands, its bud surface bearing few long foliaceous appendages, many stipitate glands and hairs and its even vibrant pink with a golden glow flower coloration that lasts throughout the life of the flower. The plant has an upright somewhat spreading growing habit, suitable for outdoor garden decoration.

Asexual reproduction of the new variety by budding as performed in Kern County and Upland, Calif., shows that the foregoing and other distinguishing characteristics come true to form and are established and transmitted through succeeding asexual propagations. ‘WEKrigoyelo’ may be asexually propagated by budding and grafting. The budding and grafting successfully occurred on the plant/rootstock Rosa hybrida cv. ‘Dr. Huey’ (unpatented).

COMPARISON WITH PARENTS

The new rose may be distinguished from its seed parent, ‘DORviso’ by the following combination of characteristics: whereas ‘WEKrigoyelo’ bears flowers of vibrant pink with a golden glow coloration, ‘DORviso’ bears flowers of deep pink coloration. The new variety has an upright somewhat spreading medium height growing habit (about 115 to about 140 cm. in height), whereas the seed parent has an upright moderately compact significantly shorter growing habit. ‘WEKrigoyelo’ bears young leaves of pale green coloration, whereas ‘DORviso’ bears young leaves of significantly darker olive green coloration.

The new variety may be distinguished from its pollen parent, an undisseminated seedling of my creation by the following combination of characteristics: whereas ‘WEKrigoyelo’ bears large sized flowers (about 8.2 to about 14.7 cm. in diameter) of vibrant pink with a golden glow coloration, the undisseminated seedling bears significantly smaller flowers (about 5.9 to about 8.4 cm. in diameter) of medium yellow coloration. The new variety is classified as a hybrid tea rose with an upright somewhat spreading medium height growing habit (about 115 to about 140 cm. in height), whereas the pollen parent is classified as a floribunda rose with a rounded and compact significantly shorter growing habit.

COMPARISON WITH THE CLOSEST COMMERCIALLY AVAILABLE CULTIVAR

The closest commercially available cultivar to the new variety is the seed parent ‘DORVISO’.

BRIEF DESCRIPTION OF ILLUSTRATION

The accompanying photograph illustrates the new variety and shows the flowering thereof from bud to full bloom depicted in color as nearly correct as it is possible to make in a color illustration of the character. Throughout this specification, color references and/or values are based upon the Colour Chart of The Royal Horticultural Society (1966) except where common terms of color definition are employed.

DESCRIPTION OF THE NEW VARIETY

The following description is of 3 to 4 year-old rose plants of the new variety grown outdoors in Upland, Calif. in the month of September. Phenotypic expression may vary with environmental, cultural and climatic conditions, as well as differences in conditions of light and soil.

FLOWER

The new variety usually bears its flowers singly. Flowers are borne on strong short to medium length stems (about 15 to about 65 cm.). Outdoors, the plant blooms abundantly and nearly continuously during the growing season. The flowers have a slight tea fragrance.

BUD

The peduncle is about 2.3 to about 5.6 cm. in length, of somewhat heavy caliper (about 0.3 to about 0.5 cm. in diameter), and usually erect to moderately stiff. It is rough with many long prickle-like stipitate glands, few hairs and some small prickles. Peduncle color is between 144A and 143A.

Before the calyx breaks, the bud is about 1.1 to about 2.0 cm. in diameter at the widest point, about 1.8 to about 2.7 cm. in length, and pointed in shape. The surface of the bud bears few long foliaceous appendages, many stipitate glands and hairs usually with slender much cut foliaceous parts extending beyond the tip of the bud about ¼ or more of its length. Bud color is between 144A and 143A.

The sepals are about 2.8 to about 4.1 cm. in length and about 0.7 to about 1.3 cm. in width at the widest point. The outer surface color of the sepal is between 144A and 143A. The inner surface color of the sepal is between 137A and 138A and covered with fine wooly tomentum; sepal margins are lined with many stipitate glands and few hairs.

The receptacle of the flower is of very short length (about 0.2 to about 0.4 cm.) and thin in caliper (about 0.4 to about 0.7 cm. in diameter). The receptacle is usually nearly flat to sometime somewhat rounded in form. Its surface is moderately smooth with few hairs and stipitates glands and with thin fleshy walls. The receptacle color is between 144A and 143A.

As the petals open (after the calyx breaks), the bud is about 2.5 to about 3.4 cm. in diameter at the widest point, about 2.8 to about 3.8 cm. in length, and moderately ovoid to somewhat pointed in form. The color of the under and upper surfaces of the newly opened petals is between 53B and 47B. At the point where the petal attaches on the under surface of the newly opened petals, there is a moderately small zone of between 3C and 4B. At the point where the petal attaches on the upper surface of the newly opened petals, there is a large zone of between 4A and 5C.

BLOOM

When fully open, the bloom ranges from about 8.2 to about 14.7 cm. in diameter. Petalage is double with about 23 to 30 petals and about 1 to 5 petaloids irregularly arranged. When partially open, the bloom form is high centered to somewhat cupped, and the petals are moderately tightly spiraled to cupped with petal edges slightly reflexed outward. When fully open, the bloom form is cupped and the petals are loosely cupped to somewhat undulated with petal edges moderately reflexed outward.

PETALS

The substance of the petals is moderately heavy and of medium to somewhat thick thickness, with upper surfaces moderately satiny and under surfaces slightly shiny to matte. The petals are about 3.7 to about 5.9 cm. in length and about 3.3 to about 6.7 cm. in width at the widest point. Petal margins are entire.

The outer petals are nearly round in shape with rounded apices.

The inner petals are broadly obovate in shape with rounded apices.

Petaloids are about 1.4 to about 3.4 cm. in length and about 0.9 to about 1.8 cm. in width at the widest point. Petaloids are irregularly shaped sometimes nearly rounded and sometimes somewhat oblanceolate with rounded apices.

NEWLY OPENED FLOWER

The under and upper surface color of the outer petals is between 63B and 58C. At the point where the petal attaches on the under surface there is a moderately small zone of between 5C and 6C. At the point where the petal attaches on the upper surface there is a large zone of between 6C and 7C.

The under and upper surface color of the intermediate and inner petals is between 58B and 51A.

The under and upper surface color of the petaloids are similar in coloration to the upper and under surfaces of the intermediate and inner petals.

The general tonality of the newly opened flower is between 58B and 51A.

THREE-DAY-OLD FLOWER

The under and upper surface color of the outer petals is between 63B and 61D sometimes fading to between 68C and 62B on the outer edge of the outer most petals. At the point where the petal attaches on the under surface there is a moderately small zone of between 5C and 6C. At the point where the petal attaches on the upper surface there is a large zone of between 6C and 7C.

The under and upper surface color of the intermediate and inner petals is between 63B and 61D.

The under and upper surface color of the petaloids are similar in coloration to the upper and under surfaces of the intermediate and inner petals.

The general tonality of the three-day-old flower is between 63B and 61D.

On the spent bloom, the petals usually drop off cleanly.

In September in Upland, Calif., blooms on the bush growing outdoors generally last about four to five days. Cut roses from plants grown outdoors and kept at normal indoor living temperatures generally last about four to five days.

MALE REPRODUCTIVE ORGANS
