USPP32589P3 - Ranunculus plant named ‘ABPEGASO’ - Google Patents

Abstract

A new and distinct cultivar of Ranunculus plant named ‘ABPEGASO’ is disclosed, characterized by plants producing a large number of very large light pink flowers with a typical vase life of 20 to 25 days. Plants have a unique foliage carriage, with foliage occurring at the base of the plant. 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: ‘ABPEGASO’.

BACKGROUND OF THE INVENTION

The new Ranunculus cultivar is a product of a planned breeding program conducted by the inventor, Alberto Biancheri at a research nursery in Camporosso Mare, Italy. The cross resulting in this new variety was made during 2013.

The seed parent is the, unpatented, variety of Ranunculus ‘ABROCHI’. The pollen parent is the unpatented, proprietary variety referred to as Ranunculus ‘131-07/A’. The new variety was discovered in 2015 by the inventor in a group of seedlings resulting from the 2013 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 2015 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 ‘ABPEGASO’ 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 ‘ABPEGASO’ These characteristics in combination distinguish ‘ABPEGASO’ as a new and distinct Ranunculus cultivar:

• 1. Very large light pink flowers.
• 2. High quantity of flowers produced per plant.
• 3. Low foliage carriage, flowers occurring high above a low growing plant.
• 4. Long vase life.
• 5. Flower diameter of 12 to 14 cm.

PARENT COMPARISON

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

• 1. Flowers of the new variety are light pink, those of the seed parent are pale salmon.
• 2. Vegetative carriage of the new variety is lower than that of the seed parent.

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

• 1. Flowers of the new variety are a different color than those of the pollen parent.
• 2. Flowers of the new variety are larger than flowers of the pollen parent.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘ABPEGASO’ are comparable to the commercial variety Ranunculus ‘ABSIRLPIN’, U.S. Plant Pat. No. 30,388. The two Ranunculus varieties are similar in most horticultural characteristics; however, the new variety ‘ABPEGASO’ differs in the following:

• 1. This comparator produces more foliage.
• 2. Flowers of the new variety are taller, 6 to 7 cm high, while flowers of this comparator are on average 3 to 4.5 cm high.
• 3. Flower color of the new variety is light pink, flower color of this comparator is more salmon colored.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph illustrates a close-up view of an individual flowers. The flowering plants of the new variety in the photograph are approximately six months old, grown in a greenhouse during April in Camporosso, Italy. 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^th edition, except where general terms of ordinary dictionary significance are used. The following observations and measurements describe 5-month-old ‘ABPEGASO’ plants grown in a greenhouse in Camporosso Mare, Italy. The plant has been described in the month of February. In order to protect the crop against pests, some chemical treatments are performed. Treatments with growth regulators can be performed to limit the plant sizes. In particular, no growth regulators have been applied on the plant described. The rhizome has been planted on raised benches in a peat and pumice substrate mixture. The growing temperature ranged from 12° C. to 26° C. during the day and from 0° C. to 6° C. during the night. General light conditions are bright, normal sunlight. Measurements and numerical values represent averages of typical plant types.
