Title: Hybrid tea rose plant named &#39;weksunvoye&#39;

Description:
CLASSIFICATION  
      The present invention relates to a new  Rosa hybrida  plant.  
     VARIETY DENOMINATION  
      The new plant has the varietal denomination ‘WEKsunvoye’.  
     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 ‘FRYxotic’ (U.S. Plant Pat. No. 9,718) and as its pollen parent an undisseminated seeding of Applicant&#39;s creation with the following genetic origin (Voodoo×unknown seedling).  
     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 large flowers of blended apricot gold coloration, its irregular yellow-colored fan-shaped pattern of venation on the under surface of the petals and its many stipitate glands on the surface of the bud. The plant has an upright moderately 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. ‘WEKsunvoye’ may be asexually propagated by budding and grafting. The budding and grafting successfully occurred on the plant/rootstock  Rosa hybrida  cv. ‘Dr. Huey’.  
     Comparison with Parents  
      The new rose may be distinguished from its seed parent, ‘FRYxotic’ by the following combination of characteristics: whereas ‘WEKsunvoye’ bears flowers of blended apricot gold with an irregular yellow-colored fan-shaped pattern of venation on the under surface of the petals, ‘FRYxotic’ bears flowers of apricot pink coloration. The new variety bears flowers with double petalage (about 16 to 28 petals), whereas the seed parent bears flowers with significantly heavier petalage (about 36 to 40 petals). On the spent bloom of the new variety, the petals usually persist, whereas on the spent bloom of the seed parent, the petals usually drop off cleanly.  
      The new variety may be distinguished from its pollen parent, an undisseminated seedling of Applicant&#39;s creation with the following genetic origin (Voodoo×unknown seedling), by the following combination of characteristics: whereas ‘WEKsunvoye’ bears flowers of blended apricot gold with an irregular yellow-colored fan-shaped pattern of venation on the under surface of the petals, the undisseminated seedling bears flowers of blended orange coloration. ‘WEKsunvoye’ bears flowers with double petalage (about 16 to 28 petals), whereas the pollen parent bears flowers with significantly lesser petalage (about 8 to 17 petals). The new variety is classified as a hybrid tea rose with an upright moderately spreading mature growing habit, whereas the pollen parent is classified as a floribunda rose with a significantly smaller and more compact mature growing habit.  
     Comparison with the Closest Commercially Available Cultivar  
      The closest commercially available cultivar to the new variety is the seed parent ‘FRYxotic’ as described herein.

     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 October. Phenotypic expression may vary with environmental, cultural and climatic conditions, as well as differences in conditions of light and soil.  
     Botanical Designation  
      The new variety botanical designation is  Rosa hybrida  ‘WEKsunvoye’.  
     Flower  
      The new variety usually bears its flowers singly, sometimes in clusters of two to three per stem. Flowers may be borne in regular rounded clusters on strong short to medium length stems (about 15 to about 50 cm.). Outdoors, the plant blooms abundantly and nearly continuously during the growing season. The flowers have a slight tea to fruity fragrance.  
     Bud  
      The peduncle is about 2.5 to about 8.2 cm. in length, of somewhat heavy caliper (about 0.4 to about 0.6 cm. in diameter), and usually erect. It is usually moderately smooth but sometimes rough, with some stipitate glands, few hairs and sometimes some small prickles. Peduncle color is between 146C and 146B sometimes lightly suffused, especially on the side exposed to the sun, with between 183C and 187A.  
      Before the calyx breaks, the bud is about 1.5 to about 2.5 cm. in diameter at the widest point, about 2.0 to about 3.2 cm. in length, and very pointed to somewhat ovoid in shape. The surface of the bud bears many foliaceous appendages and stipitate glands, usually with moderately stout much cut foliaceous parts extending beyond the tip of the bud about ¼ or more of its length. Bud color is between 137C and 146B.  
      The sepals are about 3.2 to about 4.7 cm. in length and about 1.0 to about 1.6 cm. in width at the widest point. The outer surface color of the sepal is between 137C and 146B. The inner surface color of the sepal is between 137B and 146C and covered with fine wooly tomentum; sepal margins are lined with some stipitate glands and few hairs.  
      The receptacle of the flower is of somewhat short length (about 0.5 to about 0.7 cm.) and moderately thin in caliper (about 0.7 to about 0.9 cm. in diameter). The receptacle is vase shape in form. Its surface is smooth with some hairs and with thick fleshy walls. The receptacle color is between 146C and 146B.  
      As the petals open (after the calyx breaks), the bud is about 2.5 to about 4.3 cm. in diameter at the widest point, about 3.4 to about 4.7 cm. in length, and moderately pointed to ovoid in form. The color of the under surfaces of the newly opened petals is between 33C and 47C usually showing an irregular fan shaped pattern of venation of between 13A and 13B in coloration. At the point where the petal attaches, there is a large zone of between 5C and 12B. The color of the upper surfaces of the newly opened petals is between 24B and 24C. At the point where the petal attaches, there is a large zone of between 14A and 14B.  
     Bloom  
      When fully open, the bloom ranges from about 8.7 to about 13.4 cm. in diameter. Petalage is double with about 16 to 28 petals and about 2 to 4 petaloids irregularly arranged. When partially open, the bloom form is somewhat high centered to cupped and the petals are moderately tightly spiraled to cupped to sometimes undulated with petal edges moderately reflexed outward. When fully open, the bloom form is more cupped and the petals are loosely cupped to undulated with petal edges moderately reflexed outward.  
     Petals  
      The substance of the petals is moderately heavy and of medium thickness, with upper surfaces slightly satiny and under surfaces matte. The petals are about 3.0 to about 4.9 cm. in length and about 3.4 to about 5.8 cm. in width at the widest point. Petal margins are entire.  
      The outer petals are nearly rounded in shape with rounded apices.  
      The inner petals are moderately obovate in shape with rounded apices.  
      Petaloids are about 2.4 to about 3.4 cm. in length and about 1.4 to about 3.1 cm. in width at the widest point. Petaloids are irregularly shaped somewhat obovate with rounded apices.  
     Newly Opened Flower  
      The under surface color of the outer petals is between 41C and 37A usually showing an irregular fan-shaped pattern of venation of between 4B and 12C in coloration.
