USPP19556P2 - Hybrid tea rose plant named ‘JACormag’ - Google Patents

Abstract

Hybrid tea rose plant named ‘JACormag’ having very large flowers; long cutting stems; vigorous, upright, well branched growth; and the ability to propagate well from softwood cuttings.

Description

Genus and species: Rosa hybrida.

Variety denomination: ‘JACormag’.

ORIGIN OF THE INVENTION

The present invention relates to a new and distinct variety of a hybrid tea rose plant named ‘JACormag’ which was originated by me by crossing the variety ‘JACmag’ (U.S. Plant Pat. No. 3,998, seed parent) with an unnamed Red Hybrid Tea rose (not patented, pollen parent). The pollen parent is a cross between two unnamed red hybrid tea rose varieties.

BACKGROUND OF THE INVENTION

The primary objective of this breeding was to produce a new hybrid tea rose variety having the large flower size and vigorous plant of the female (seed) parent combined with the long stems and own root vigor of the unnamed red hybrid tea male (pollen) parent.

BRIEF SUMMARY OF THE INVENTION

The objective was substantially achieved, along with other desirable improvements, as evidenced by the following unique combination of characteristics that are outstanding in the new variety and that distinguish it from its parents, as well as from all other varieties of which I am aware:

• • 1. Very large flower.
  • 2. Vigorous, upright, well branched growth.
  • 3. Propagates well from softwood cuttings.
  • 4. Long cutting stems.

Asexual reproduction of this new variety by cuttings, as performed at Wasco, Calif., shows that the foregoing characterictics and distinctions come true to form and are established and transmitted through succeeding propagations.

Comparison with Parents

‘JACormag’ differs from ‘JACmag’ in flower color (apricot to ivory pink for ‘JACmag’ versus orange-red for ‘JACormag’). ‘JACormag’ differs from the unnamed pollen parent in flower color (orange-red for ‘JACormag’ versus red for the pollen parent).

Comparison with Similar Variety

The closest variety is believed to be ‘JACirst’ (U.S. Plant Pat. No. 10,230). ‘JACormag’ differs from ‘JACirst’ in flower color (coral orange for ‘JACirst’ versus orange-red for ‘JACormag’).

BRIEF DESCRIPTION OF THE ILLUSTRATION

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

DETAILED BOTANICAL DESCRIPTION
