Hybrid tea rose plant named ‘JACpribe’

Abstract

Hybrid tea rose plant having vigorous, but compact growth habit; large, well-formed flowers borne one per stem; thick petals; leathery foliage; and good disease resistance.

Description

Genus and species: Rosa hybrid.

Variety denomination: ‘JACpribe’.

ORIGIN OF THE INVENTION

The present invention relates to a new and distinct variety of a hybrid tea rose plant named ‘JACpribe’ which was originated by me by crossing the variety ‘POULman’ (U.S. Plant Pat. No. 6,264) with the variety ‘JACpico’ (U.S. Plant Pat. 3,997).

BACKGROUND OF THE INVENTION

The primary objective of this breeding was to produce a new rose variety having a compact plant, strong leathery foliage and the disease tolerance of the female parent combined with the high centered flower form and thick petals of the male 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. Vigorous, but compact growth habit.
  • 2. Large, well-formed flowers borne one per stem.
  • 3. Thick petals.
  • 4. Leathery foliage.
  • 5. Good disease resistance.

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

COMPARISON WITH PARENTS

‘POULman’, the female parent, is a red hybrid tea with flowers on stems of 30 to 45 cm. It is resistant to powdery mildew and rust and very tolerant to blackspot. The male parent, ‘JACpico’, is also a hybrid tea but with white flowers having a pink blush on 40 to 50 cm stems. It is resistant to powdery mildew and rust but susceptible to blackspot.

COMPARISON WITH SIMILAR VARIETY

‘JACpribe’ is a very compact hybrid, ideal for containers. Well formed flowers are produced singly on short stems. This combined with good disease tolerance makes it a unique variety. It differs from ‘JACpal’ (U.S. Plant Pat. No. 8,591) in having shorter stems, a more compact plant and improved disease resistance.

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.
