Method for obtaining FLORIBUNDA roses

The invention relates to a rose with new permanent forms that can be reproduced in this permanent form Properties, namely a rose of the class of JFloribunda roses with raised flowers in the middle of a velvety red color, whose properties suit the needs the horticultural industry, especially for the production of cut flowers.

A process for obtaining the new Floribunda rose by planting the new cultivar are propagated vegetatively that have one or several stages have been obtained from the mother plant of the new variety, this mother plant in turn

was the result of the breeding measures specified below. It is therefore a process that, through its application to a certain genre as the starting material, namely to the according to the Invention bred new variety is characterized, this new variety was obtained by the specific method described below, is placed under protection in addition, the extraction and use of the blossoms that grow from the multiplied rose plants as cut goods.

The breeder's goal was to get a Floribunda rose züohten, which would no longer have certain deficiencies that have been identified up to now, in particular no excessive spine formation, no lack of growth and no insufficient ones Resistance to fungal diseases and no insufficient flowering time

In order to obtain a rose with these characteristics, the breeder has an artificial insemination (crossing) carried out, assuming two cultivated plants, of which he expected based on previous observations that the desired properties and characteristics would appear in their common offspring. ' "CHRISTIAH DIOR" known variety, as father plant (pollen carrier) the variety known in trade as "RUMBA" ·

The artificial insemination carried out by the breeder (Crossing) can thus be expressed by the following schematic formula.

«CHRISTIAN DIOR« X "RUMBA"

seeds were removed from the fruits resulting from this controlled fertilization (crossing) and their cells were formed from the combination of the pactors present in the cells of the parent plants, because of which | it was precisely these parent plants that were selected.

From a seed field created with these seeds, the breeder pulled 650 seedlings that were physiologically and biologically different distinguished from each other, and which were moved to a greenhouse to be observed there. The inventor 634 specimens were eliminated that had either developed poorly and abnormally or their characteristics differed significantly from those that formed the goal of its breeding. The breeder then took a refinement of the remaining ones Specimens and examined a selection of the plants produced in this way, and he grafted all of them Rose bushes were eliminated with the exception of a single plant that came closest to the desired breeding goal.

The flowers of this plant were raised in the middle and had a velvety red color. She bloomed

plentiful, in all seasons, and especially those The second bloom was very good, and it also stood out through good resistance to fungal diseases

It was now necessary to check whether there were possible uses for this rose that were suitable to interest the Q-arboriculture industry. A number of experiments were carried out in the greenhouse and in the open air to assess fertility as well as the reaction of the plant in different climatic conditions and at different times of the year The results were very positive and underlined the importance of this newly bred variety, especially with regard to it on their industrial evaluation for the production of cut flowers.

The characteristics and properties of this new variety obtained according to the above information are sexlessly transferable, i.e. to any type of vegetative Propagation, especially by grafting on an "eye" (Inoculating), which is known in the trade as "d'oeil de LAHdo 616". So aan receives the rose variety anew, the The subject of the invention is, the botanical and descriptive features of which are listed below
