DE1582520A1 - Process for the production of dwarf roses by vegetative propagation of their mother plants - Google Patents

Description

through vegecative propagation of their mother plants.

The invention relates to a new rose permanent and in this permanent form reproducible properties, namely on a rose of the class of Miniature roses, whose exceptionally well-filled flowers have a camellia pink color, those of roses Class is absolutely new and therefore meets the requirements of the horticultural industry with regard to the creation of Borders, rock gardens, alpinums and as a potted plant particularly corresponds and in every way for decoration can be used by parks and gardens »

A process for the production of roses of this new variety is placed under protection, namely by vegetative

Propagation of their mother plant

The aim pursued by the applicant was to obtain a rose variety to breed whose characteristics correspond to those of dwarf plants and whose flowers are special and attractive Camellia pink in color.

To breed this rose variety, the notifying party initially selected two parent plants, of which it was based previous observations could expect that their common offspring would have the desired properties would occur.

The rose chosen as the mother plant was a new floribunda rose, from a cross of the variety MEIkim 00175 F (trade name DANY ROBIN) with the variety MEIkans 00152 P (Trade name PIRE KING). The rose chosen as the father plant was the one on the market under the name PERLE DE MONiESERRAT known variety, Artificial insemination carried out by the applicant can be expressed by the following schematic formula:

The fruits resulting from this directed fertilization were there. Samples taken, the cells of which have grown through the combination of factors that had formed in the

Cells of the parent plants were present and on the basis of which precisely these parent plants had been selected.

From the sowing of these seeds, the applicant received 240 small plants, which are in their external and biological Features differentiated from each other. After sorting out all defective and anomalous specimens or such Specimens whose features and features differ from the ones sought star * deviated, the applicant took an oiculation of the remaining plants in order to continue the cultivation work only with those rose plants that are in agreed in every respect with those who were bred and sold by the professional tree nursery gardeners will.

She then examined the individual bred this way Plants for the purpose of further selection. This investigation led to the systematic elimination of all inoculated rose plants with the exception of one that came closest to the set breeding goal.

The vegetative characteristics of this rose plant corresponded to those of the dwarf plants. She was strong and had flowers the heavily filled wareu and a special and attractive camellia pink color indicate.

Technical experiments were then undertaken (oculating in hot and cold conditions, with a driving eye and non-driving eye, at various OJculation sites, in the warm and cold greenhouse, etc.) to the behavior of the variety bred in this way. The results obtained provided the desired evidence and underlined the importance of breeding this variety with a view to its industrial exploitation by the professional tree nursery gardener to decorate parks and gardens.

The characteristics and properties of this new rose variety, which as described above was grown, can readily asexually, ie through any kind of vegetative propagation are transmitted, in particular by grafting an "eye" which is commercially the term ^w oeil de MEImini 0541 i " ¹ 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, the rose variety which is the subject of this patent application is obtained again, the botanical characteristics and properties of which are described below :

The color terminology corresponds to that of the Horticultural Color Chart of the Royal Horticultural Society.
