DE1131454B - Vegetative propagation of mother plants of a floribunda rose - Google Patents

Description

The invention relates to the continuous vegetative propagation of mother plants of a floribunda rose with half-double flowers in the color Indian orange yellow, as opposed to them in their coloring the floribunda roses known so far in the horticultural industry is absolutely new, over any multiplication stages to the sales item.

The novel rose represents an essential step in the color development of the floribunda roses as it is the first rose that succeeded in a perfect way, usually as an orange-yellow or capuchin red color.

The inventor had been doing this for a long time due to its extraordinary commercial nature Interest posed that brought a floribunda rose with the aforementioned color because there is also no floribunda rose of similar flower color.

In order to obtain a rose variety that exhibits the characteristics mentioned, the inventor of the artificial borrowed Fertilization, for which he selected two parent plants, of which he is more precise on the basis previous observations could expect their common offspring to produce the desired Have properties and in particular the flower color you are looking for.

Each of the parent plants selected by the inventor came from a cross between two varieties, the vegetative propagation of mother plants under the name GOLDILOCKS a floribunda rose
