Rose plant--Jofitali variety

Abstract

A rose plant of the Grandiflora Class, obtained as a bud mutation of the variety Sweet Promise (known in the United States as Sonia) (U.S. Plant Pat. No. 3,095). The flower of this new variety is Rose Bengal on the inside and Spiraea Red on the outside.

Description

SUMMARY OF THE INVENTION

The object of the present invention is a variety of rose-plant of the Grandiflora Class, whose vegetative type corresponds to that of the variety Sweet Promise, (known in the United States as Sonia) (U.S. Plant Pat. No. 3,095) but whose flowers, although of the same form, are distinguishable because of a very luminous Rose Bengal color, instead of Porcelain Pink touched up with Begonia Pink in depth.

The variety of rose-plant, object of the present invention, is the result of a selective study carried out on numerous plants formed by grafting the new matter (new eye-bud) arising from a bud mutation of the said variety Sweet Promise.

In view of the interest that would be created, in the horticultural industry, by the disclosure of the different technical effect presented by the new variety as compared with the original variety, it was advisable to propagate the said new variety on a large scale in order to check its behavior, from the physical as well as the biological point of view.

The results were conclusive and underlined the importance of disclosing such a variety, with a view to its industrial exploitation by the professional nurserymen and the producers of cut flowers.

The characters and properties of this new variety, obtained as indicated above are strictly transmissible by agamic means, also called "asexual", i.e., by any means of vegetative propagation, in particular by grafting an "eye" which will be called in the trade by the name of Jofitali 0944 F. NL. and which will be found on industrial plants as well as on cut stems delivered subsequently in the trade.
