Hybrid tea rose plant named Machoro

Abstract

A new hybrid tea rose plant producing red flowers.

Description

SUMMARY OF THE INVENTION

The present invention relates to a new and distinct variety of rose plant of the hybrid tea rose class which was originated by my crossing as seed parent the variety known as `Macspeego` and as pollen parent the variety known as `Macbucpal`. The varietal denomination of this new rose is `Machoro`.

Among the novel characteristics possessed by this new variety which distinguish it from its parents and all other varieties of which I am aware are its attractive red flowers with ruffled petal edge.

Blooms of `Machoro` are larger than blooms of both its parents and are less fragrant than both its parents.

Asexual reproduction by budding of the new variety as performed in Watsonville, Calif. shows that the foregoing and other distinguishing characteristics come true to form and are established and transmitted through succeeding propagations.

BRIEF DESCRIPTION OF ILLUSTRATION

The accompanying illustration shows typical specimens of the vegetative growth and flowers of the new variety in different stages of development and depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.

DETAILED DESCRIPTION OF THE NEW VARIETY

Parentage: Seedling. Seed parent: `Macspeego`. Pollen parent: `Macbucpal`.

Class: Hybrid tea.

The following is a detailed description of my new variety, of specimens grown outdoors in Watsonville, Calif. in the month of June.
