' Int. Cl. Anni 5/00 US. Cl. Plt.--17 1 Claim ABSTRACT OF THE DISCLOSURE A new and distinct variety of hybrid tea rose plant originated from crossing two unnamed varieties, one produced from crossing Baccara with White Knight, which was crossed on a variety obtained by crossing Baccara with Meibrem 172 F (Jolie Madame), and the other variety used as parent was obtained from crossing the variety Baccara with the variety Meibis .137'F (Paris- Match).

DESCRIPTION OF THE INVENTION Purity and freshness of color of the flowers;

Unusual elegance of these flowers;

Very well suited to underglass culture for'the production of long-stemmed cut flowers;

Suited just as well to growing in the open air, as a garden variety;

Development of a foliage more ample and more resistant to fungus diseases, particularly to powdery mildew. ,Be cause of the above-mentioned characteristics, the present invention answers the needs of the horticultural industry for the production of cut flowers, as well as for all uses concerning. the ornamentation of parks and gardens.

Y The aim that I had in view was to create a variety which would derive the aforementioned advantages through a genetic combination of two genitors whose previous respective study would allow me to expect, in their common progeny, the appearance of thecharacters sought for.

The ro'se chosen for female genitor (seed parent) came from the pollination of a yet unknown variety which had been obtained by crossing two varieties, also yet unknown, and resulting:

The first one, from the crossing of the variety generally known in the trade under the name of Baccara (Plant Pat. No. 1,367) and of the variety generally known in the trade under the name of White Knight (Plant Pat. No. 1,359).

The second one, from the crossing of the said variety Baccara and the variety Meibrem 172 F, more generally known in the trade under the name of Jolie Madame.

The rose chosen as male genitor (pollen) was an unknown variety obtained from crossing the variety Baccara and the variety Meibis 138 F, more generally known in the trade under the name of Paris-Match.

The operation of artificial pollination performed by Plant Pat. 2,977 Patented July 7, i970 me can therefore be expressed by the following schematic formula: i i i From the fruits formed by this controlled pollination, seeds were extracted, whose cells were the result of the combination offactors which existed in the cells of the genitors, and in virtueof which these genitors had been precisely chosen.

After having sown the above-mentioned seedsfl obtained 530 small plants, physically and biologically distinct from one' another.

After having discarded all the small plants which were deficient or abnormal, orwhose characters were 'too remote'from the ones I wasseeking, I proceeded with the grafting of the remaining plants, in order to carry on my work only on plants that w'er'e,:in every respect, in con formity with" those produced and commercialized by the professional nursery-men. I then undertook the selective study of the industrial plants thus formed. During this study, I was led to discard systematically all the rose plants which had been grafted, with the exception of one only which came the closestto the desired goal.

This rose plant had very elegant flowers; its light Scarlet color was very pure. Moreover, it was continuously producing long stems with an ample and especially healthy foliage.

Technical tests (grafting with started eye buds, dormant eye buds, on different understocks, in'hothouses or cold greenhouses, in the open air, etc.) were then made in order to watch the behavior of the newly created variety. The results were conclusive and'underlined' the importance of creating this variety with a view to its industrial exploitationby horticulturists, for the production of cut flowers, and by the professional nurserymen for the ornamentation of parks and gardens. 7

The characters and properties of this. new variety, obtained as indicated above, are thoroughly transmittable by agamic means, also called asexual'means, i.e. by any method .of vegetative reproduction, and in particular by grafting an eye which will be called in the trade under the name of Meiretni 0593 F, and which will be found on industiral plants just as well as on cut stems delivered subsequently to the trade. Thus will be obtained once again the rose variety which is theobject of the present invention, and whose botanical and descriptive characteristics are given below:

The following is a detailed description of my new variety with color terminology in accordance with the horticultural color chart of the Royal Horticultural Society:

(A) GREENHOUSE PLANTS Class: Hybrid tea. Plant: height-1m. 80 on an average; habit-erect. Canes:
