ROSE PLANT Filed Sept. 22, 1967 United States Patent 2,932 ROSE PLANT Stefano Calvino, Strada Coldirodi 65, Sanremo, Italy Filed Sept. 22, 1967, Ser. No. 669,981 Claims priority, application Italy, Nov. 30, 1966, 43,216/ 66 Int. Cl. A01h 5/02 U.S. Cl. Plt.-19 1 Claim The aim of this present invention was to obtain a new variety of rose, better than the varieties commonly grown, and more suitable for supplying the most recent needs of international flower markets. A rose of a bright pink, tending to red, has been lacking on the market for some time, and thus the applicant suggested carrying out research to find this particular variety, using various opportune methods.

The plant required had to have not only the tonality of color desired, but also all the other characteristics which qualify the commercial rose; in other words, a graceful flower shape, easily opening corolla, petals of good consistency, resistant to packing and transport, resistance of flower color to atmospheric difliculties; vigorous and strong growth, with stems and leaves in proportion to the flower, resistant to inclement weather and disease, simple to cultivate, and very productive in industrial cultivation.

The plant which is the subject of the present invention adheres in the greatest possible degree to the requirements which were the basis of the applicants research, and can thus be considered as a positive result of the studies carried out.

The variety which is the subject of the present invention has been obtained by the genetic cross-breeding of different varieties of roses, appropriately chosen, according to the laws of genetic science.

After numerous fruitless attempts because of the difliculty of determining the variety to use in cross-breeding, it was at last possible to isolate, from a wide stock of hybrid varieties produced previously by the applicant with pollen of the type known commercially by the name of Ninfa Rossa the plant which is the object of the present invention, in which, with successive careful multiplication, it has been possible to fix the necessary requisites. The variety Ninfa Rossa is here identified as a sport (lusus naturae) of the variety Nymph obtained by A. Dickson in 1953 and which was derived from the variety Fashion unnamed seedling, which has varied the color coral-salmon of its flowers. Nymph variety is named in Modern Roses V Ed. McFarland New York, page 279, and in American Rose Annual 1966-Ed. American Rose Society, page 229.

The variety which is the subject of the present invention need not be reproduced by repeating the crossbreeding carried out in order to obtain it. Such operations constitute a laboratory procedure which is not necessary in order to produce the invention. It can in fact be easily reproduced and multiplied in any number of specimens and thus on an industrial scale, on the part of the breeder, by means of one of the vegetative reproduction methods commonly used in floriculture (cutting, grafting, layering, etc.) and in particular by grafting axillary buds of the plant according to the present invention or of another plant derived from it by vegetative means, on graft recipients suitable for the soil on which it is intended to carry out the cultivation.

When repeatedly reproduced by this method, the plant which is the subject of the present invention has constantly and faithfully transmitted all its distinctive char acteristics in its subsequent descendants, making its cultivation possible for the production of cut flowers for Plant Pat. 2,932 Patented Oct. 21, 1969 the market and for ornamental plants in parks and gardens.

The characteristics in their unique combination, which differentiate the variety which is the subject of the present invention from other varieties of its class, and which define it, follow in a list, provided as a non-limiting example in description, taken from a set of plants cultivated according to industrial criteria, in the open air and under glass, on a sunny hillside in the month of October.

It is always necessary to bear in mind the season and the climate in order to evaluate any possible difference in characteristics that may occur due to diverse conditions. These differences must be considered normal at least until, repeating the cultivation of the plant described, in the same conditions, it is possible to identify the plant by means of the collection of the characteristics given in the description.

The naming of the colors in the description have been made according to the tables of the Horticultural Color Chart by Robert F. Wilson (indicated in the text by the initials HCC), except in the cases where the color was absent from the tables or where its indication was sufficiently clear according to common parlance.
