Title: Rose plant named `Burworld`

Description:
The present invention relates to a new and distinct variety of rose plant of the hybrid tea rose class, which was originated by my crossing as seed parent the rose known as &#34;First Prize&#34; and the rose known as &#34;Gold Glow&#34; as pollen parent. The new rose is known by the denomination &#34;Burworld&#34;. 
     Among the novel characteristics possessed by this new variety which distinguish it from its parents and all other varieties of which I am aware are vibrant, red and yellow bicolored, high centered, singly borne blooms. Asexual reproduction by budding of the new variety as performed in Smith County, Tex., shows that the foregoing and other distinguishing characteristics come true to form and are established and transmitted through succeeding propagations. 
     The new and improved rose variety which I have developed is an unusually fine hybrid tea rose with singly-borne blooms of high centered, excellent hybrid tea form. The flowers are of medium petalage and have a slight fragrance. The brilliant coloring holds well upon aging. 
    
    
     The accompanying drawing shows typical specimens of the vegetative growth and flowers of the new variety in different stages of development and as depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character. 
    
    
     The following is a detailed description of my new variety, with color terminology in accordance with the Royal Horicultural Society Colour Chart (R.H.S.C.C.). The terminology used in color description herein refers to plate numbers in the aforementioned color chart, e.g., &#34;50A&#34; is plate 50A of the Royal Horticultural Society Colour Chart.

     Seed parent.--&#34;First Prize&#34;.
