Ranunculus Cultivar ABPEGASO Breeding for Large Pink Flowers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new Ranunculus cultivar that exhibits distinct characteristics such as large light pink flowers, high flower production, low foliage carriage, and long vase life, which are not met by existing varieties under varying environmental conditions.
Innovation Solution
The cultivar 'ABPEGASO' is developed through planned breeding, combining traits like very large light pink flowers, high flower quantity, low foliage carriage, and long vase life, achieved through asexual reproduction by vegetative division and tissue culture, distinguishing it from its seed and pollen parents and commercial comparators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If existing Ranunculus varieties are used, then they can be grown under standard conditions, but they fail to produce large light pink flowers with long vase life
Solution Approach 1:
The patent uses tissue culture to create exact genetic copies of the selected Ranunculus plant, ensuring that the unique features (large light pink flowers, long vase life) are replicated precisely across multiple generations without genetic variation
Solution Approach 2:
The patent changes the propagation method from sexual reproduction to asexual reproduction through tissue culture, which maintains genetic stability and ensures consistent expression of desirable traits across generations
2Area of moving object
If Ranunculus varieties with large flowers are selected, then flower size increases, but flower quantity per plant decreases
Solution Approach 1:
The patent selects a specific plant that exhibits both large flower size and high flower quantity, then propagates this local excellence through tissue culture to maintain both characteristics simultaneously in all subsequent plants
Solution Approach 2:
The patent changes the propagation approach to tissue culture, which preserves the specific combination of large flower size and high flower quantity by maintaining identical genetics across all propagated plants
3Shape
If foliage carriage is reduced for better flower display, then flower visibility improves, but overall plant biomass decreases
Solution Approach 1:
The patent selects a plant with the specific local quality of low foliage carriage that allows flowers to stand out, then propagates this trait through tissue culture to maintain the distinctive plant architecture across all plants

AI summary
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.
