Description

BACKGROUND OF THE NEW PLANT

This new variety of rose plant is a result of my crossing "Jacqueline" (U.S. Plant Pat. No. 2,183) with an undisseminated seedling #4-68R in the fall of 1979 at Richmond, Ind., with the object of producing a Hybrid Tea Rose. The varietal denomination of this new claimed cultivar is `Hildred`. The claimed plant is also known as 2-80R.

The claimed plant was asexually reproduced through successive generations by grafting in Richmond, Ind., and at Livermore, Calif., showing that the distinctive characteristics of the claimed cultivar hold true and appear to be firmly fixed. This new variety can also be asexually propagated by budding, grafting, propagation from cuttings and micropropagation.

DESCRIPTION OF THE DRAWINGS

This new Hybrid Tea Rose is illustrated by the accompanying full color photographic drawing which shows buds in several stages of opening, a face view of a fully opened blossom, specimens of typical leaves, a specimen of young wood with new leaves, a specimen of wood and leaves with a newly formed bud, and typical specimens of mature wood.

This new rose plant cultivar is a superior plant when it is judged on its long pointed bud form and its clear, bright red color makes it an improvement over seed parent "Jacqueline" (U.S. Plant Pat. No. 2,183). It is better than its pollen parent in productivity and keeping qualities. The claimed plant most closely resembles Hybrid Tea Rose plant named Buram (U.S. Plant Pat. No. 7,052) (hereinafter "Buram") and Rose plant Arotrusim (U.S. Plant Pat. No. 7,157) (hereinafter "Arotrusim"). The average size of the flowers of Buram and Arotrusim are larger than that of the claimed plant. Both the claimed rose and Arotrusim bloom continuously in a greenhouse where Buram blooms only recurrently. Furthermore, the bud of the claimed rose is short and pointed without a conspicuous neck whereas the bud of Buram is ovoid and high centered and the bud of Arotrusim is long and pointed. The color of the foliage of the claimed plant is green whereas in Buram the old foliage is purplish green and the new foliage is yellow green. The old foliage of Arotrusim is reddish brown and the new foliage is matt green. Both Buram and Arotrusim are disease resistant and have some winter hardiness. The claimed cultivar is not disease or frost resistant.

Claims

1. A new and distinct Hybrid Tea Rose cultivar, substantially as herein shown and described, characterized by its long pointed buds, the clear bright red color of the flower petals, and by its moderately free and continuous flower production under greenhouse culture.
