Abstract
A new and distinct Ranunculus cultivar named ‘ROCYELLOW’ is disclosed, characterized by cold-hardy plants producing multiple yellow flowers with red flecks The new variety is a Ranunculus, useful as an ornamental plant or for cut flower production.
Description
Latin name of the genus and species: Ranunculus cortusifolius x asiaticus.
Variety denomination: ‘ROCYELLOW’.
The new Ranunculus cultivar is a product of a planned breeding program conducted by the inventor, John Fielding in London, United Kingdom at his home garden. The objective was to produce varieties that are garden hardy in zone 8, and suitable for cut flower or garden uses. The cross resulting in this new variety was made in April of 2004.
The seed parent is an unnamed, unpatented Ranunculus cortusifolius. The pollen parent is an unnamed, unpatented Ranunculus asiaticus. The new variety was discovered in April 2009 by the inventor in a group of seedlings resulting from the 2004 crossing, in London, United Kingdom.
Asexual reproduction of the new cultivar was first performed by division in July 2009 at the inventor's home garden. The unique features of this cultivar are stable and reproduced true to type in more than 10 successive generations. Date of first sale of the new cultivar was Oct. 1, 2018, in the Netherlands.
The cultivar ‘ROCYELLOW’ 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 ‘ROCYELLOW’ These characteristics in combination distinguish ‘ROCYELLOW’ as a new and distinct Ranunculus cultivar:
-
- 1. Garden hardy in zone 7 or 8, has been observed to survive −15° Celsius in garden trials.
- 2. Can be used for cut flower or garden uses.
- 3. Cut flower will last in water for 12 to 14 days, with all flowers opening.
- 4. Branched stems with multiple flowers per stem.
- 5. Flower color is yellow with splashes and flecks of deep red.
Plants of the new cultivar ‘ROCYELLOW’ are similar to plants of the seed parent, in most horticultural characteristics, however, plants of the new cultivar ‘ROCYELLOW’ differ in the following:
-
- 1. The seed parent is taller than the new variety.
- 2. Flowers of the new variety are yellow with red flecks, while the seed parent's flowers are golden yellow without markings.
- 3. The seed parent has 5 petals per flower, while the new variety has typically 17-21 petals.
Plants of the new cultivar ‘ROCYELLOW’ are similar to plants of the pollen parent, in most horticultural characteristics, however, plants of the new cultivar ‘ROCYELLOW’ differ in the following:
-
- 1. The pollen parent is shorter than the new variety.
- 2. The pollen parent is less winter hardy than the new variety.
- 3. The pollen parent has fewer flowers per stem than the new variety.
Plants of the new cultivar ‘ROCYELLOW’ are comparable to the unpatented commercial variety Ranunculus ‘Amandine Yellow Picotee’. The two Ranunculus varieties are similar in most horticultural characteristics; however, the new variety ‘ROCYELLOW’ differs in the following:
-
- 1. Vegetative carriage, foliage occurs lower on plants of the new variety.
- 2. Flowers of the new variety produce less petals and have an open center not found in this comparator.
- 3.The new variety is tolerant of more cold temperatures than this comparator.
The accompanying photograph in FIG. 1 illustrates in full color flowering plants of the new variety at approximately 1 year old, grown outdoors.
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.
In the following description, color references are made to The Royal Horticultural Society Colour Chart 6th edition, except where general terms of ordinary dictionary significance are used. The following observations and measurements describe 18-month-old ‘ROCYELLOW’ plants grown in a vented, unheated polytunnel in London, United Kingdom. No chemical treatments were performed. The growing temperature ranged from 5° C. to 25° C. during the day and from −5° C. to 10° C. during the night. General light conditions are bright, normal sunlight. Measurements and numerical values represent averages of typical plant types.
