Abstract

A new and distinct variety of miniature rose plant, referred to by its cultivar name, ‘AYA NO4’, is disclosed. The new variety forms attractive, small double pink colored flowers. Attractive semi-glossy foliage is formed, which contrasts beautifully with the blossoms. A bushy growth habit is displayed. The new variety is well suited for providing attractive ornamentation in the landscape.

Description

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

Variety denomination: ‘AYA NO4’.

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to Plant Breeders' Right Application Number 2022/0168, which was filed at Community Plant Variety Office in the European Union on Jan. 19, 2022, the contents of which are hereby incorporated by reference for all purposes.

STATEMENT REGARDING PRIOR DISCLOSURES BY THE INVENTOR

The first offer for sale of the new variety was Mar. 19, 2021 in Kenya. The first 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 rose plant of the present invention was discovered in Spring 2017 in Saitama pref., Japan as a spontaneous mutation of ‘AYA NO5’ (not patented). The new variety was selected and preserved primarily because of its different pink flower color from the flower color of the ‘AYA NO5’ parent variety, which is commonly near Red-Purple Group 68B.

The new variety has been found to undergo asexual propagation in Le Cannet des Maures, Var, France by a number of routes, including eye budding, softwood cuttings, semi-hardwood cuttings, and hardwood cuttings. Asexual propagation by the above-mentioned techniques in Le Cannet des Maures, Var, France has shown that the characteristics of the new variety are stable and are strictly transmissible by 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 rose plant of the present invention possesses the following combination of characteristics:

- (a) forms pink colored flowers,
- (b) produces small double flowers, and
- (c) exhibits a semi-glossy 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 of the present invention can readily be distinguished from its ancestors. More specifically, the ‘AYA NO5’ variety (i.e., parent variety) displays a more compact growth habit compared to the new variety in that the new variety is taller than the ‘AYA NO5’ variety. Moreover, the new variety can be readily distinguished from other similar non-parental varieties. For example, the ‘HOHOEMI ROUGE’ variety (U.S. Plant Pat. No. 31,646) has darker pink colored flowers and longer stems compared to the new variety.

The new variety has been named ‘AYA NO4’.

DETAILED BOTANICAL DESCRIPTION

The chart used in the identification of the colors is that of The Royal Horticultural Society (The R.H.S. Colour Chart, 2001 edition), London, England. 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 one-year-old specimens of the new variety during June while budded by cuttings and growing in greenhouses at Le Cannet des Maures, Var, France.
