Floribunda rose plant named ‘KORteidros’

Abstract

A new and distinct variety of Floribunda Rose Plant, herein referred to by its cultivar name, ‘KORteidros’, is provided which forms in abundance on a substantially continuous basis attractive, medium red colored blossoms with a cream reverse. The vegetation is vigorous and the growth habit is very bushy and compact. Attractive ornamental glossy, dark green foliage is formed. The new variety is particularly well suited for providing distinctive ornamentation in the landscape.

Description

Botanical/commercial classification:

Latin name—Rosa hybrida.

Common name—Floribunda Rose Plant.

Varietal denomination: ‘KORteidros’.

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to Plant Breeders' Right Application Number 2017/2303, which was filed at Community Plant Variety Office in the European Union on Sep. 20, 2017, the contents of which are hereby incorporated by reference for all purposes.

SUMMARY OF THE INVENTION

The new variety of Rosa hybrida Floribunda Rose Plant of the present invention was created during May 2005 at Offenseth-Sparrieshoop, Germany by artificial pollination wherein two parents were crossed which previously had been studied in the hope that they would contribute the desired characteristics. The female parent (i.e., seed parent) of the new variety was an unnamed seedling from a previous cross between an unnamed seedling (non-patented in the United States) and the ‘KORpeligo’ variety (non-patented in the United States). The male parent (i.e., pollen parent) of the new variety was the ‘KORfloci08’ variety (U.S. Plant Pat. No. 19,362).

The parentage can be summarized as follows:
(unnamed seedling x ‘KORpeligo’) x ‘KORfloci08’

The seeds resulting from the above pollination were sown and small plants were obtained which were physically and biologically different from each other. Selective study resulted in the identification of a single plant of the new variety.

It was found that the new Floribunda Rose Plant of the present invention possesses the following combination of characteristics:

• • (a) abundantly and substantially continuously forms attractive, medium red colored blossoms with a cream reverse,
  • (b) exhibits a very bushy and compact growth habit,
  • (c) forms vigorous vegetation, and
  • (d) forms attractive ornamental glossy, dark green foliage.

The new variety well meets the needs of the horticultural industry. It can be grown to advantage as ornamentation in parks, gardens, public areas, and in residential settings. Accordingly, the plant is particularly well suited for growing in the landscape.

The new variety can be readily distinguished from its ancestors. More specifically, the (unnamed seedling x ‘KORpeligo’) variety (i.e., seed parent) exhibits a lower petal count, a less bushy growth habit, and a different flower color compared to the new variety. Additionally, the ‘KORfloci08’ variety (i.e., pollen parent) exhibits a less rounded flower shape and less disease resistance compared to the new variety and displays orange-red colored flowers, whereas the new variety displays medium red colored flowers with a cream reverse. Moreover, the new variety can be readily distinguished from non-parental related similar varieties. For example, the ‘JACzotta’ variety (U.S. Plant Pat. No. 12,128) displays less petals and is taller and wider compared to the new variety.

The new variety has been found to undergo asexual propagation in Klein Offenseth-Sparrieshoop, Germany by a number of routes such as budding. Asexual propagation techniques in Germany, such as budding, have shown that the characteristics of the new variety are homogeneous, stable, and strictly transmissible by such asexual propagation from one generation to another. Accordingly, the new variety undergoes asexual propagation in a true-to-type manner.

The new variety has been named ‘KORteidros’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph shows, as nearly true as it is reasonably possible to make the same in color illustrations of this character, a typical specimen of the new variety. The illustrated rose plant of the new variety was approximately two years of age and was observed at Offenseth-Sparrieshoop, Germany while growing outdoors on understock in July 2017.

DETAILED BOTANICAL DESCRIPTION

The chart used in the identification of colors is that of The Royal Horticultural Society (R.H.S. Colour Chart, 2015 edition). The terminology which precedes reference to the chart has been added to indicate the corresponding color in more common terms. The description is based on the observation of a three-year-old specimen of the new variety, observed during June, while growing in a field on its own roots at Cochranville, Pa.
