DE1130637B - Vegetative propagation of mother plants of a tea hybrid - Google Patents

Description

The invention relates to the continuous vegetative propagation of mother plants of a tea hybrid with double, two-tone flowers, which are covered in strawberry-red and velvety purple-red on top and are predominantly amber-yellow on the back, over any propagation stages up to the point of sale.

In the horticultural industry, there are several varieties of hybrid tea with double, two-tone Flowers known. However, these varieties have certain shortcomings. The new hybrid tea makes a difference stands out from the well-known two-tone varieties

their strong and vigorous growth, their great abundance of flowers,

its very double, very large and extremely well-formed flowers,

the new color of the strawberry-red and velvety purple-red on the top Flowers that are predominantly amber yellow on the reverse side,

the firm petals that cause the flowers to cut both in and out are long-lasting in the uncut state.

To grow this rose, the inventor proceeded as follows:

As usual, the inventor carried out thousands of crosses by means of artificial insemination by. Due to the laws of inheritance and the method used, the inventor was able to make his own direct breeding efforts to the solution of the specific task mentioned. To a To create a variety of roses that has the above-mentioned characteristics, plants of two different ones were made Thousands of varieties of roses crossed. The mother rose (seed carrier) belongs to the trade as HENRI MALLERIN's well-known variety. The father rose is a cross between the ROUGE varieties MEILLAND (HAPPINESS) and FLORIDA emerged.

As a result of this controlled fertilization, numerous fruits were formed, the seeds of which were removed became. The cells of these seeds combined certain factors selected in the parent plants had been. The seeds were therefore biologically different from those which did would have emerged from a natural fertilization, because they arose as a result of the fusion of two cells, those of diverse, vegetative reproduction of mother plants a hybrid tea

France of June 10, 1958 (No. 38 443)

Francis Meilland f, Cap d'Antibes (France), has been named as the inventor

parent plants selected from certain criteria.

The above-mentioned seeds were sown, whereupon the inventor received 480 little plants that were related to their appearance and biological characteristics are different from each other. Not all of these plants had the characteristics sought. The inventor therefore had to sort out those plants that weren't were suitable to contribute to the solution of the given task. The inventor then examined the Systematic characteristics and properties of each retained plant. This again led to a Series of excretions, with only seventeen retained after excretion of a total of 463 plants became.

As with all roses, almost every leaf axil was found in the retained plants an "eye" that was distinguished by its particular vigor, d. that is, it developed extremely vigorously on a root system called a graft.

In order to fully develop the characteristics found on these retained plants and to ensure its constancy, the inventor removed eyes from every plant, which he pointed to suitable Grafted documents. A few months later, perfectly viable rose

Plants with abundant roots and very well developed foliage.

In the years that followed, they worked on the plants systematic investigations carried out with regard to their characteristics. and observations on Elimination of all grafted varieties, with the exception of a single one that meets the requirements fully corresponded.

This plant was tall, very upright, and had sturdy stems. The flowers were very numerous densely filled and well shaped. The top of the flowers was strawberry-red and velvety purple-red, the reverse is predominantly colored amber. This was a completely new color. In addition, the flowers were durable for a long time due to the firm petals.

The inventor set out now to determine whether the new rose variety with regard to its possible uses the horticultural industry would be interested in. It led to the determination of profitability and reaction of the plant under different climatic conditions and in different seasons Try both outdoors and in a greenhouse. The results of these experiments were positive and confirmed the importance of the new plant to the horticultural industry, namely for use in dense plantings as well as grown in the field or in the greenhouse Cut flower and as an ornamental plant for gardens and plants.

The characteristics and properties of this rose, bred as described above, can consistently be passed on in an asexual way, also referred to as "genderless" which guarantees the durability of this rose indefinitely. Suffice it to be a "Eye" that is found both on industrial plants and on the flower stalks that are commercially available are to be found, to be removed and to graft this in any way on a base in order to to bring about the emergence of a plant which is completely identical to the newly grown plant. This goal can also be achieved by propagation using cuttings is carried out by parts of plant tissue derived from the newly grown rose plant, whose distinguishing features are listed below:
