Description

"concerning
Process for the extraction of geerose hybrids.

The invention relates to a rose with new permanent properties that can be reproduced in this permanent form, namely on a rose of the class of! ee-hybrids with double, at the edges carmine-red and otherwise Chinese coral-red flowers, which differ from the previously known species of this class and color in their entirety Harmony and perfection distinguish and their flowers have a very pronounced tea rose fragrance and a very charming one Have coloring, whereby the 35 atlas-like petals are highlighted, the flowers also have a perfect, circular shape with a raised center and the plant is of remarkable vigor, abundance of flowers and Bless you.

The new rose variety offers these special characteristics the horticultural industry the best technical prerequisites to decorate parks and gardens »

A process for obtaining the new tea rose hybrids is placed under protection, in which plants of the new variety are vegetatively propagated that have been obtained from the mother plant of the new variety in one or more stages and this mother plant in turn being the result of the breeding measures specified below . Ss thus involves a process which is characterized by its application to a particular property, genus as the starting material, namely the acc of the invention cultured new variety, which ψ new strain has been obtained by the method described below certain procedures.

The aim pursued by the applicant was to breed a Rose, which combines the advantages mentioned above, through the genetic combination of two parent plants, from which she could expect based on previous observations, that the desired properties would appear in their common offspring "

The rose chosen as the mother plant was the rose variety _{: iü} i, CHARLOSTE ARMSTRONG and the rose chosen as the father plant was the product of crossing the varieties MABAME A. MEIUiAKD and MICKBLE MEILLANB. The artificial insemination carried out by the applicant can be expressed by the following formula:

The fruits resulting from this controlled fertilization were taken from seeds, the cells of which spread through the combination of the factors that were present in the cells of the parent plants and due to of which these parent plants were chosen.

From sowing these seeds, the applicant obtained 385 plant loops which differed from one another in their external and biological characteristics. After sorting out * all defective or anomalous specimens or those specimens whose characteristics differed from the ones sought, the notifier proposes an inoculation of the remaining plants in order to continue the breeding work only with those rose plants that correspond in every respect to those of the professional ones Nursery gardeners are bred and sold.

She then examined the individual plants grown in this way for the purpose of further selection. This I study led to the systematic elimination of all okulierten rose plants except one that came with the set breeding goal the next.

This rose plant produced flowers that were perfectly shaped, a very distinctive tea rose cult and their color is of a rare peculiarity

was. She was also remarkably strong, had one extraordinary abundance of flowers and their foliage was always. healthy#

Then technical attempts have been made (budding in heat and cold, with drifting eye and not drifting eye at various Okulierungsstellen, in hot and cold greenhouse, etc.) ψ to the behavior and profitability of aui this way to check bred variety. The results obtained provided the desired proof and underlined the importance of the cultivation of this variety with regard to its industrial use by professional tree nursery gardeners for the decoration of parks and gardens.

The characteristics and properties of this new rose variety, which as described above was grown, can readily asexually, ie any kind durqh of vegetative propagation are transmitted, in particular by grafting an ^N eye ^n, commercially called "oeil de MEIdali 053B F "and that will be found on industrial plants as well as on cut flower stems that are later commercially available. In this way, again rose variety that ^u UBJECT of the patent application are described una whose botanical Merkmaie and properties below.
