USPP36659P2 - Miniature rose plant named ‘KORpot135’ - Google Patents

Abstract

A new and distinct variety of miniature rose plant, referred to by its cultivar name, ‘KORpot135’, is described. The new variety forms in abundance on a substantially continuous basis, pink-colored blossoms. The growth habit is compact. Semi-glossy ornamental foliage is formed. Additionally, the new variety is particularly well suited for growing as distinctive ornamentation in the landscape.

Description

Latin name of genus and species of plant claimed: Rosa hybrida.

Variety denomination: ‘KORpot135’.

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to Plant Breeders' Right Application No. 2247391, which was filed at Community Plant Variety Office in the European Union on Sep. 19, 2024, the contents of which are hereby incorporated by reference for all purposes.

STATEMENT REGARDING PRIOR DISCLOSURES BY THE INVENTOR

The first sale or offer for sale of the new variety was November 2023, on the Rosa Danica website (rosa-danica.dk). The first sale or offer for sale of the new variety was by the inventor or another who obtained the new variety directly or indirectly from the inventor. No plants of the new variety have been sold in this country or anywhere in the world, nor has any disclosure of the new plant been made, more than one year prior the effective filing date of this application, and such sale or disclosure within one year was either derived directly or indirectly from the inventor.

BACKGROUND OF THE INVENTION

The new variety of miniature rose plant of the present invention was created by controlled breeding during 2018, in 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., the seed parent) of the new variety was an unnamed breeder seedling (not patented). The male parent (i.e., the pollen parent) (not patented) of the new variety was a product of the cross between the ‘RUId244a’ variety (not patented) and a different unnamed breeder seedling (not patented).

The parentage of the new variety can be summarized as follows:
unnamed breeder seedling x (‘RUId244a’ x different unnamed breeder seedling)

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.

The new variety has been found to undergo asexual propagation in Klein Offenseth-Sparrieshoop, Germany by a number of routes such as vegetative cuttings. Asexual propagation techniques in Klein Offenseth-Sparrieshoop, Germany, such as vegetative cuttings, 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.

SUMMARY OF THE INVENTION

It was found that the new variety of miniature rose plant of the present invention possesses the following combination of characteristics:

• • (a) forms pink-colored blossoms,
  • (b) provides double flowers with a rounded shape, and
  • (c) exhibits a compact growth habit.

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 residential landscapes. Accordingly, it is particularly well suited for growing in the landscape.

The new variety can be readily distinguished from its ancestors. More specifically, the new variety displays a more rounded flower shape, and a smaller flower size compared to the unnamed breeder seedling parent (i.e., the seed parent). Additionally, the new variety displays a less intense pink flower color and a more compact growth habit compared to the pollen parent. Moreover, the new variety can be readily distinguished from non-parental related similar varieties. For example, the new variety displays a lower number of petaloids per flower and a more rounded flower shape compared to the ‘KORpot064’ variety (U.S. Plant Pat. No. 29,042).

The new variety has been named the ‘KORpot135’ variety.
