- Int. Cl. AOlH /00 US. Cl. Pit-20 1 Claim ABSTRACT OF THE DISCLOSURE I A new and distinct variety of rose plant of the hybrid tea class, originated by crossing unnamed and unpatented seedlings, and obtaining a bright Vermilion color of its flowers, with great aptitude of the plant for forcing.
SUMMARY OF THE INVENTION The object of the present invention is a variety of rose plant of the hybrid tea class, with semi-double Vermilion flowers, which is distinguishable from varieties already known in that class and in that color, because of the following characteristics:
particularly attractive originality of the bright Vermilion color of its flowers;
great aptitude of the plant to forcing; and
good steadiness of growth of the forced plants.
Because of the characteristics mentioned above, the present invention answers the needs of the horticultural industry, for all uses, and more particularly for the production of cut flowers.
The aim of the applicants was to create a variety which would derive the aforementioned advantages from the genetic combination of two genitors whose previous and respective study would allow them to expect, in their common descent, the appearance of the characters sought.
The rose chosen as female genitor was an unnamed and unpatented product of the pollination of a yet unknown variety born of a crossing made between the variety Show Girl and the variety Meger561, more generally known in the trade under the name of Baccara, by the variety Meialto-2l9F, more generally known in the trade by the name of Romantica; the rose chosen as male genitor was the product of the pollination of the variety Meialto-219F, more generally known in the trade under the name of Romantica by the variety Tanorstar, more generally known in the trade under the name Super Star.
The operation of artificial pollination performed by the schematic formula:
Meger-561 Baccara,
M eialto-Z 19F Show Girl X R mantica 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 these seeds the applicant obtained 490 small plants, physically and biologically distinct from one another.
After having eliminated all the plants which were deficient or abnormal, or whose characters were too remote from the ones they were seeking, the applicants proceeded with the grafting of the remaining plants, in order to carry on their work exclusively on rose plants which were, in
every respect, in conformity with those produced and commercialized by professional nurserymen.
From then on, they undertook the selective study of the plants thus formed, during which study they were led to eliminate systematically all the rose plants which had been grafted, with the exception of one only, which came the closest to the desired goal.
This variety was endowed with a bright Vermilion color, original and attractive, and showed great aptitude to forcmg.
Technical tests (grafting inside or outside, with dormant eye-buds, started eye-buds, in heated glasshouses, in cold glasshouses, on various understocks) were then made so as to ascertain the behavior of the variety just created.
The results were conclusive and underlined the impor tance of creating this variety with a view to its industrial exploitation for all uses, especially for the production of cut flowers.
The characters and properties of this new variety, obtained as indicated above, are strictly transmissible by agamic means, also called asexual, i.e. by any means of vegetative propagation, and in particular by grafting an eye which will be designated in the trade by the name of eye of Meinastur 0852F and which will be found on industrial plants as well as on cut stems delivered subsequently in the trade. Thus will be obtained once again the new rose variety and whose botanical and descriptive characteristics, observed on glasshouse plants, are given below:

DETAILED DESCRIPTION OF DISCLOSURE 3 CLASS: Hybrid tea PLANT: Development: considering the plants having been cut back to .85 m., the length of the flowering stems will be between 50 to 70 cms.
Habit: erect BRANCHES:
Color: young stems: before buds are formed, they are light green on the shaded side, reddish purple on the sunny side; as and when buds form, they turn to bronze green, then to light green 146/C (yellow-green group); mature wood: medium green 146/A (yellow-green group) Prickles: shape: upper edge: straight, inflexed towards the base; under edge: concave, base: obovate, narrow; size: medium to small; quantity: medium to small, they are sometimes intermixed with needle-shaped points on the very vigorous branches; color: on young stems: before buds are formed, they are light reddish purple; then in succession, they turn to greenish with a pink point, and to greenish and light straw (common terms); on mature wood: light havana (common term) LEAVES:
Stipules: adnate, pectinate, narrow and linear Petiole: obverse: the inside and edges of the rib are reddish brown in the young foliage, medium green in the adult foliage; the edges are generally slightly, to very slightly glandular; reverse: light green, withsmall prickles, hooked and greenish white; position: it forms with the stern an angle between 45 and 90 Folioles: number: 3-5-7; shape: on a standard model leaf, on the average /2 of a flower-bearing branch (1st pair starting from the top); base: rounded, asymmetrical; top: wide, symmetrical; general shape: elliptical; teeth: single and fine; texture: leathery; general effect: ample foliage, medium dense, shiny on young stems before the buds are formed; semi-dull afterwards; color: young foliage; upper surface: dark green 147/A (yellow-green group), shiny; under surface: light green, between 19l/A and 191/B (greyed-green group) sometimes lightly satin-like reddish; adult foliage; upper surface: dark green l47/A (yellowgreen group) semi-dull; under surface: light green between 191/A and 191/B (greyed-green group) It is to be noted that when growth starts, as also during the course of vegetation, the foliage of the young shoots is reddish purple-on the upper and under surface.
