Title: Rose plant named ‘Poulpah110’

Description:
Botanical designation:  Rosa hybrida.    
     Variety denomination: ‘Poulpah110’. 
     This application claims priority to Plant Breeder&#39;s Rights Application Number 2021/2364, which was filed at the Community Plant Variety Rights Office in the European Union on Sep. 24, 2021, 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 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 2016 and the resulting seeds were planted in a controlled environment in Fredensborg, Denmark. The new variety, named ‘Poulpah110’, 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 yellow flowers while the new variety has orange flowers. The female seed parent plant has small orange flowers, with a diameter of 55 mm, while the newly claimed plant has larger flowers 80 mm in diameter. 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 orange flowers;   2. Vigorous, but compact growth when propagated on its own roots;   3. Suitability for production in six inch containers; 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 ‘Poulpah110’ 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 2016 and conducted evaluations on the resulting seedlings in a controlled environment in Fredensborg, Denmark. ‘Poulpah110’ was selected in the spring of 2017 by the inventor as a single plant from the progeny of the aforementioned hybridization. 
     Asexual reproduction of ‘Poulpah110’ by rooted cuttings was first done by Mogens N. Olesen in the nursery in Fredensborg, Denmark in July, 2017. This initial and other subsequent asexual propagations conducted in controlled environments have demonstrated that the characteristics of ‘Poulpah110’ are true to type and are transmitted from one generation to the next. 
    
    
     
       DESCRIPTION OF THE DRAWING

     DETAILED DESCRIPTION OF THE VARIETY 
     The following is a description of ‘Poulpah110’, as observed in its growth in a glass house located in Odense Denmark. Observed plants are 6 months of age, and were grown on their own roots in 24 cm containers. 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 rose variety ‘Poulpah070’, U.S. Plant Pat. No. 27,641 are compared to the claimed plant ‘Poulpah110’. The general tonality of flower for the claimed plant is Open flowers are Yellow-Orange Group 23B with intonations of Orange-Red Group 31A. As the flower matures color changes to Yellow-Orange Group 18A and other colors of Orange Group 29A. The general tonality of the comparison variety ‘Poulpah070’ is Yellow-Orange Group 23C with other intonations of Orange Group 25C and Orange-Red Group 32B. The claimed plant has a flower diameter of 80 mm while the comparison variety has a flower diameter of 55 mm.
