Ranunculus Cultivar ABOTSO 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 light pink flowers, high productivity, and consistent flower quality throughout the harvest season, while being stable across varying environmental conditions.
Innovation Solution
The cultivar 'ABOTSO' is developed through planned breeding, combining traits like light pink flowers, larger flower size, and enhanced vegetative carriage, achieved through asexual reproduction by vegetative division and subsequent tissue culture propagation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a new Ranunculus cultivar is developed through planned breeding to achieve distinct characteristics, then flower color, flower size, and vegetative carriage are improved, but breeding time and program complexity increase
Solution Approach 1:
The patent applies preliminary action by conducting planned breeding programs in advance to develop the new cultivar 'ABOTSO' with predetermined desirable traits. The breeding process was initiated during 2010, allowing sufficient time for selective crossing and stabilization of characteristics before commercial release.
2Shape
If a new Ranunculus cultivar is developed to exhibit distinct characteristics, then flower color, flower size, and vegetative carriage are improved, but the complexity of the breeding program increases
Solution Approach 1:
The breeding program is segmented into distinct phases: seed parent selection ('ABROCHI'), pollen parent selection ('131-07/A'), controlled crossing during 2010, seedling evaluation in research greenhouses, and propagation through tissue culture. This segmentation allows systematic management of complex breeding operations.
3Reliability
If the cultivar is propagated by tissue culture to ensure stability, then reproduction fidelity is improved, but propagation complexity and cost increase
Solution Approach 1:
The patent employs tissue culture propagation to create identical genetic copies of the selected cultivar 'ABOTSO'. This copying process ensures that all propagated plants maintain the exact same genotype and phenotypic characteristics as the original selected plant, guaranteeing reproduction fidelity across multiple generations.
4Productivity
If the cultivar is selected for large corolla production and high productivity, then flower quantity and quality are improved, but selection criteria and evaluation processes become more complex
Solution Approach 1:
The breeding program incorporates feedback mechanisms where seedlings are evaluated for corolla size, flower quality, and productivity characteristics. Plants exhibiting superior traits like large corollas and high productivity are selected for further propagation, while those not meeting standards are eliminated from the breeding program.

AI summary
A new and distinct cultivar of Ranunculus plant named ‘ABOTSO’ is disclosed, characterized by light pink flowers and a large corolla. Plants produce a high quantity of quality, large size flowers throughout the harvest season. The new variety is a Ranunculus, normally produced as a cut flower and potentially useful as an ornamental plant.
