Abstract

A new and distinct Ranunculus cultivar named ‘ABSIRLPIN’ is disclosed, characterized by flowers of a very light pink shade. Plants are and produce an above average quantity of flowers of high quality throughout the flowering season. Flower size produced remains large throughout the flowering season. The new variety is a Ranunculus, normally produced as a cut flower and potentially useful as an ornamental plant.

Description

Latin name of the genus and species: Ranunculus asiaticus.

Variety denomination: ‘ABSIRLPIN’.

BACKGROUND OF THE INVENTION

The new Ranunculus cultivar 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 2011.

Parent varieties are both, unpatented, undistributed proprietary varieties of Ranunculus asiaticus. The new variety was discovered in 2014 by the inventor in a group of seedlings resulting from the 2011 crossing, in a research greenhouse in Camporosso Mare, Italy.

Asexual reproduction of the new cultivar was 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 2014 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 ‘ABSIRLPIN’ 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 ‘ABSIRLPIN’ These characteristics in combination distinguish ‘ABSIRLPIN’ as a new and distinct Ranunculus cultivar:

- 1. Exceptionally light pink flower color.
- 2. Large corolla production throughout the flowering season.
- 3. Exceptionally strong plants.
- 4. Above average quantity and quality of flower stems produced during the flowering season.

PARENT COMPARISON

Plants of the new cultivar ‘ABSIRLPIN’ are similar to plants of the seed parent, in most horticultural characteristics, however, plants of the new cultivar ‘ABSIRLPIN’ differ in the following;

- 1. The new variety has a different flower color. The new variety has a primary petal color of Red 49D, and a secondary color of Orange 27D. The seed parent has a single petal color of Red 38D.
- 2. Flower diameter of ‘ABSIRLPIN’ has an average range of 10 to 14 cm, flower diameter of the seed parent is on average in the range of 8 to 10 cm.

Plants of the new cultivar ‘ABSIRLPIN’ are similar to plants of the pollen parent, in most horticultural characteristics, however, plants of the new cultivar ‘ABSIRLPIN’ differ in the following;

- 1. The new variety has a different flower color. The new variety has a primary petal color of Red 49D, and a secondary color of Orange 27D. The pollen parent has a single petal color of Red-Purple N57D.
- 2. Flower diameter of ‘ABSIRLPIN’ has an average range of 10 to 14 cm, flower diameter of the pollen parent is on average in the range of 8 to 10 cm.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘ABSIRLPIN’ are comparable to the unpatented commercial variety Ranunculus ‘ABLIGHTPIN’. The two Ranunculus varieties are similar in most horticultural characteristics; however, the new variety ‘ABSIRLPIN’ differs in the following:

- 1. Flower color of the new variety is lighter pink.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color flowering plants of the new variety at approximately five months old, grown in a greenhouse.

FIG. 2 illustrates a close up of plant parts. The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart 6^thedition, except where general terms of ordinary dictionary significance are used. The following observations and measurements describe ‘ABSIRLPIN’ plants grown in a greenhouse Camporosso Mare, Italy. The plant described has been cultivated under glass, planted in the months of September and described in the month of February. One must always refer to these conditions of season and culture, when considering the present description. By reason of different climate or culture conditions, differences may arise between certain characteristics of the plant and the corresponding characteristics of the description. It should be considered as normal and do not modify the essence of the present invention because it will possible to identify the plant by means of the totality of the characteristics given in the description. The rhizome has been planted on raised benches in a peat and pumice substrate mixture. The growing temperature ranged from 12° C. to 25° C. during the day and from 2° C. to 8° C. during the night.
