Ranunculus plant named ‘ABOGMA’

A new and distinct Ranunculus cultivar named ‘ABOGMA’ is disclosed, characterized by a distinctive color combination in the corolla of green and lavender. The flower has a rounded shape when fully open, and the petals are deeply ruffled. This variety has an exceptionally long vase life as a cut flower. The new variety is a Ranunculus, normally produced as a cut flower and also potentially useful as an ornamental plant.

Latin name of the genus and species:Ranunculus asiaticus.

BACKGROUND OF THE INVENTION

The newRanunculuscultivar is a product of a planned breeding program conducted by the inventor, Alberto Biancheri in Camporosso Mare, Italy. The cross resulting in this new variety was made during 2007.

The seed parent is the, unpatented, proprietary variety referred to asRanunculus‘PPBsfRS159.05’. The pollen parent is the unpatented, proprietary variety referred to asRanunculus ‘68CMT03’. The new variety was discovered in 2010 by the inventor in a group of seedlings resulting from the 2007 crossing, in a research greenhouse in Camporosso Mare, Italy.

Asexual reproduction of the new cultivar was first performed by vegetative division of buds sprouting from the rhizome of the selected plant. Subsequent propagation has been performed by tissue culture. First propagation took place at a research greenhouse in Camporosso Mare, Italy in 2010 and has shown that the unique features of this cultivar are stable and reproduced true to type in multiple successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘ABOGMA’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘ABOGMA’ These characteristics in combination distinguish ‘ABOGMA’ as a new and distinctRanunculuscultivar:1. Particular combination of color in the corolla, including lavender and green.2. Rounded shape of the flower when it is fully open.3. Deeply ruffled petals.4. Exceptionally long vase life.5. High productivity.

PARENT COMPARISON

Plants of the new cultivar ‘ABOGMA’ are similar to plants of the seed parent, in most horticultural characteristics, however, plants of the new cultivar ‘ABOGMA’ differ in the following;1. Flower color. Flowers of the new variety are a moderate purple-pink with a strong yellow-green center. The seed parent is white to pale pink with a strong yellow-green center.2. Androecium has been completely transformed to petals in the seed parent, whereas in the new variety it is rare, some stamens and anthers are found.

Plants of the new cultivar ‘ABOGMA’ are similar to plants of the pollen parent, in most horticultural characteristics, however, plants of the new cultivar ‘ABOGMA’ differ in the following;1. Flower shape. Flowers of the new variety are taller, flowers of the pollen parent are more flattened, somewhat hemispherical in shape.2. Different combination of colors in the corolla. The parent variety is lighter pink and lacks the yellow-green coloration found in the new variety.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘ABOGMA’ are comparable to the unpatented commercial varietyRanunculus‘Aazur White Striped’. The twoRanunculusvarieties are similar in most horticultural characteristics; however, the new variety ‘ABOGMA’ differs in the following:1. The new variety produces flowers with more lavender and green in the corolla.2. Flower shape of the new variety is more fully round.3. Petals of the new variety are stronger than those of this comparator.4. Floral vase life of the new variety is longer.
