United States Patent 3,452 ROSE PLANT Marie-Louise Meilland, Cap dAntibes, France, assignor to The Conrad-Pyle Company, West Grove, Pa. Filed Jan. 10, 1972, Ser. No. 216,817 Claims priority, application France, Jan. 15, 1971, 7102259 Int. Cl. A01h /00 US. Cl. Plt.20 1 Claim ABSTRACT OF THE DISCLOSURE A rose plant of the hybrid tea class, with double red flowers, produced 'by crossing the variety Lovita (Plant Pat. No. 2,598), as pollen parent, on an unnamed seedling, as seed parent, which was the product of crossing Baccara (Plant Pat. No. 1,367) on Queen Elizabeth (Plant Pat. No. 1,257).
BACKGROUND OF THE DISCLOSURE The object of the present invention is a variety of rose plant of the hybrid tea class, with double red flowers, which is distinguishable from varieties already known in that class and that kind of color, due to the following characteristics:
(1) Brightness and luminosity of the color of its flowers, more accentuated, especially under artificial light;
(2) Superior yield of the plant when forced, owing to its particularly vigorous and abundant vegetation, and to its capacity for sending forth strong shoots;
(3) Flowers lasting a very long time when cut.
Because of the characteristics mentioned above, the present invention answers the needs of the horticultural industry for the production of. cut flowers, as well as all uses intended for the ornamentation of parks and gardens.
The aim which the applicant had in view was the creation of a variety which. would derive the aforesaid advantages from the genetic combination of two genitors whose previous andrespective study would allow her to expect, in their common descent, the appearance of the characters desired.
The rose chosen as female genitor (seed parent) was an unnamed seedling which was the product of the pollination of the variety Baccara (Plant Pat. No. 1,367), by the variety Queen Elizabeth (Plant Pat. No. 1,259). The rose chosen as male genitor (pollen parent) was the variety Lovita (Plant Pat. No. 2,598).
The operation of artificial pollination performed by the applicant is expressed by the following schematic formula:
(Baccara Queen Elizabeth) Lovita From the fruits thus formed by this controlled pollination, seeds were extracted whose cells were the result of the combination of factors which existed in the cells of the genitors and in virtue of which these genitors had been precisely chosen.
After having sown the above-mentioned seeds, the applicant obtained 490 small plants, physically and biologically distinct from one another.
After having discarded all the plants which were deficient or abnormal, or whose characters were too remote from the ones she. was seeking, the applicant proceeded with the grafting of the remaining plants, in order to carry on her Work only on rose-plants which were, in every respect, in conformity with those produced and commercialized by professional nurserymen.
She then undertook the selective study of the individual plants thus formed; during this study, she was led to eliminate systematically all the rose-plants which had been grafted, with the exception of only one, which came the closest to-the desired goal.
This rose plant was producing flowers of a remarkable bright and luminous red color; moreover, they lasted a very long time when cut. The vegetation of the plant was particularly vigorous and abundant, producing new strong shoots.
Technical tests (grafting inside or outside, with started eye-buds or dormant eye-buds, on different understocks, in heated or cold greenhouses, etc.) were then made in order to ascertain the behavior of the newly created variety. The results were conclusive and underlined the importance of creating this variety with the view to its industrial exploitation by horticulturists for the production of cut flowers, and by professional nurserymen for the ornamentation of parks and gardens.
The characters and properties of this new variety, obtained as indicated above, are thoroughly transmissible by asexual means, he by any method of vegetative propagation, and in particular by grafting an eye and which will be found on individual plants as well as on cut stems delivered subsequently to the trade.
Asexual reproduction of this new variety by grafting and budding shows that its characteristics and distinctions come true to form and are transmitted through succeeding propagations.
