Description

concerning
Process for the production of tea rose hybrids,

The invention relates to a rose with new permanent properties that can be propagated in this permanent form, and a rose of the hybrid tea class with double, light madder red flowers that are drowned out in carmine-lacquer red and which differs from the previously known species of this class and color in that the buds are half open have a very attractive shape and great perfection, that the color of the flowers is no less attractive and that the flowers have a lovely scent of mayrose. With these new characteristics, this rose variety offers the horticultural industry the best technical prerequisites for decorating parks and gardens.

A process for obtaining the new tea rose hybrids by planting the new variety is placed under protection which have been obtained from the mother plant of the new variety over one or more stages and where this mother plant itself was the result of the breeding measures given below. It is about It is a process that, through its application to a certain genre as the starting material, namely to the new cultivar bred according to the invention is characterized, this new cultivar being characterized by what is described below certain procedure was won

The aim pursued by the Anmelderia was to breed a rose variety with the advantages mentioned above would unite, namely through the genetic combination of two parent plants, of which they were due to previous Observations could expect that the desired traits would appear in their common offspring became. .

The rose chosen as the mother plant was the ^{variety known commercially under the name SUTTER 1} S GOLB. The rose chosen as the Yater plant was the product of crossing the DEMAIN rose variety with the MADAME A. MEILLAND rose variety. The artificial insemination carried out by the applicant can be expressed by the following formula:

SUITER'S GOLD

χ
(DEMAIN χ Mme. A. MEILLAND).

The fruits resulting from this controlled fertilization were taken from seeds, the cells of which had been formed by the combination of the factors which were present in the cells of the parent plants and on the basis of which precisely these parent plants had been selected.

From sowing these seeds, the applicant obtained 270 small plants which differed from one another in their external and biological characteristics. After sorting out all defective or anomalous specimens or those specimens whose properties differed from the ones sought, the applicant undertook 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 used by professional tree nursery gardeners * are bred and marketed.

She then examined the individual rose plants grown in this way for the purpose of further selection. This investigation led to the systematic excretion of all oculated rose plants with the exception of one, that came closest to the set breeding goal.

This rose plant produced flowers with a very strong fragrance

which have a very warm, medicinal madder red shade I.

possessed, which was drowned out carmine-lacquer red. This shade was of a special peculiarity and the half-opened buds were perfect and very attractive in shape. also was the plant was very vigorous and had fairly dense and lush foliage.

109828/0116

Technical experiments were then undertaken (oculating "in hot and cold conditions, with a driving eye and not driving eye, at different grafting parts, Im warm and cold greenhouse, etc.) to the behavior and the To test the productivity of the variety bred in this way. The results obtained provided the desired evidence and underlined the importance of breeding of this variety in view of its industrial use by professional tree nursery gardeners for decoration of parks and gardens.

The characteristics and properties of this new rose variety, which was bred as described above, can easily be transferred in an asexual way, ie by any type of vegetative propagation, in particular by inoculating an "eye ¹¹ , which is commercially called" oeil de MEIfour 0536 F "and which will be found both on industrial plants and on flower stems that have been cut off and later commercially available. In this way, one again obtains the rose variety which is the subject of this patent application and whose botanical characteristics are described below.

The color terminology corresponds to the Oberthür color directory.
