1. 11. A new and distinct variety of rose plant named ‘Poulpmt010’ substantially as described and illustrated herein.

Botanical designation: Rosa hybrida. 
Variety denomination: ‘Poulpmt010’.
This application claims priority to Plant Breeder's Rights Application Number 2024/2182, which was filed at the Community Plant Variety Rights Office in the European Union on Sep. 19, 2024, the contents of which are hereby incorporated by reference for all purposes.
SUMMARY OF THE INVENTION
The present invention constitutes a new and distinct variety of hybrid tea rose plant which originated from a controlled crossing between the female seed parent, an unnamed seedling, and the male pollen parent, also an unnamed seedling. Both of the parent varieties are non-patented.
The two parents were crossed during the summer of 2012 and the resulting seeds were planted in a controlled environment in Odense, Denmark. The new variety, named ‘Poulpmt010’, originated as a single seedling from the stated cross.
The new variety may be distinguished from its male pollen parent and female seed parent primarily by the following characteristics. The male pollen parent plant has light pink flowers while the new variety has red and orange yellow reverse bi-color flowers. Flowers of the female seed parent plant exhibit colours of Red-Purple Group N57A and Yellow Group 12A, while colours exhibited in ‘Poulmpt010’ are primarily Red Group 53C and Orange Group 27A.
The objective of the hybridization of this rose variety was to create a new and distinct variety with unique qualities, such as:

    
    
        1. Uniform and abundant red and orange yellow reverse bi-color flowers;
        2. Strong rose perfumed scent,
        3. Vigorous, but compact growth when propagated on its own roots; and
        4. Exceptional disease resistance.
    
    


This combination of qualities is not present in previously available commercial cultivars of this type, known to the inventor, and distinguish ‘Poulpmt010’ from all other varieties of which we are aware.
As part of the rose development program, Mogens N. Olesen germinated the seeds from the aforementioned hybridization during winter of 2012 and conducted evaluations on the resulting seedlings in a controlled environment in Odense, Denmark. ‘Poulpmt010’ was selected in the spring of 2013 by the inventor as a single plant from the progeny of the aforementioned hybridization.
Asexual reproduction of ‘Poulpmt010’ by rooted cuttings was first done by Mogens N. Olesen in the nursery in Odense, Denmark in July 2013. This initial and other subsequent asexual propagations conducted in controlled environments have demonstrated that the characteristics of ‘Poulpmt010’ are true to type and are transmitted from one generation to the next.



DESCRIPTION OF THE DRAWING
The accompanying color illustrations show as true as is reasonably possible to obtain in color photographs of this type, the typical characteristics of the buds, flowers, leaves, and stems, of ‘Poulpmt010’.
Specifically illustrated in FIG. 1 of the drawings are open flowers viewed from the side and above, flower petals detached showing distinct bi-colouration, sepals detached revealing the reproductive flower parts, and flower buds.
Specifically illustrated in FIG. 2 of the drawings are juvenile leaves, juvenile bare stem, mature leaves, and mature stem exhibiting prickles. Plants shown are 15 months of age.



DETAILED DESCRIPTION OF THE VARIETY
The following is a description of ‘Poulpmt010’, as observed in its growth in an outdoor nursery in Odense Denmark. Observed plants are 15 months of age, and were grown on their own roots in 30 cm pots. Color references are made using The Royal Horticultural Society (London, England) Colour Chart, 2001, except where common terms of color are used.
For a comparison, several physical characteristics of the most similar rose variety, ‘WEKmamoprela’, U.S. Plant Pat. No. 35,384, are compared to the claimed plant. While ‘Poulpmt010’ has 42 flower petals, ‘WEKmamoprela’ has 27 to 39 flower petals. The petal undersurface of ‘Poulpmt010’ is Orange Group 27A shaded with other intonations of Red Group 48D and Yellow Group 8B towards the basal zone. The upper petal surface of ‘Poulmpt010’ are Red Group 45B with intonations of Yellow Group 8A at the basal zone. The undersurface of flower petals of ‘WEKmamoprela’ are White 155D, & 155C, with other intonations of Red-Purple Group 64B at the margins. Above petal surface of ‘WEKmamoprela’ is Red-Purple Group 61C and 66B.
