Miniature rose plant named ‘Meiludoca’

Abstract

A new and distinct Miniature rose plant is provided which abundantly forms on a substantially continuous basis attractive bronze colored blossoms. Such blossoming commonly begins early in the season. A bushy growth habit is displayed that is well adapted for pot culture. The dense semi-glossy green foliage contracts nicely with the bronze colored blossom coloration. The tolerance to disease is good, particularly with respect to Oidium.

Description

Botanical/commercial classification: Rosa hybrida/Miniature Rose Plant.

Vareital denomination: cv. Meiludoca.

SUMMARY OF THE INVENTION

The new variety of Rosa hybrida Miniature rose plant was created 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 the ‘Meichanso’ variety (non-patented in the United States). The ‘Meichanso’ variety is marketed under the PARADOR trademark. The male parent (i.e., the pollen parent) was the product of the cross of the ‘Delpo’ variety (non-patented in the United States) and the ‘Savalife’ variety (U.S. Plant Pat. No. 5,482). The ‘Delpo’ variety is marketed under the DIABLOTIN trademark and the ‘Savalife’ variety is marketed under the RAINBOW'S END trademark. The parentage of the new variety can be summarized as follows:
‘Meichanso’×(‘Delpo’בSavalife’).

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 variety of Miniature rose plant of the present invention displays the following combination of characteristics:

• • (a) exhibits a bushy growth habit that is well adapted for pot culture,
  • (b) abundantly forms on a substantially continuous basis attractive bronze colored blossoms, and
  • (c) forms attractive dense semi-glossy green foliage.

The new variety flowers early and well meets the needs of the horticultural industry. It is particularly well suited for growing in pots as well as in the landscape. For instance, it can be grown to advantage along walkways and in mixed border plantings. The semi-glossy green foliage contrasts well with the bronze colored blossom coloration.

The new variety of the present invention can be readily distinguished from its ancestors. The flower coloration is different in each instance. More specifically, the ‘Meichanso’ variety forms geranium red flowers, the ‘Delpo’ variety forms light red flowers, and the ‘Savalife’ variety forms yellow flowers that are margined with red.

The new variety has been found to undergo asexual propagation in France by a number of routes, including budding, grafting, and cuttage. Asexual propagation by the above-mentioned methods as performed in the South of France has shown that the characteristics of the new variety are strictly transmissible from one generation to another.

The new variety has been named ‘Meiludoca’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph shows as nearly true as it is reasonably possible to make the same, in a color illustration of this character, typical specimens of the plant parts of the new variety. The rose plants of the new variety were approximately one year of age and were observed during April while growing outdoors on their own roots at LeCannet des Maures, Var, France. Dimensions in centimeters as well as a color comparison are shown at the bottom of the photograph.
