Calibrachoa Suncalkuki Trailing Habit and Yellow Flower Breeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new trailing and freely-branching Calibrachoa cultivars with unique and attractive flower coloration that can reproduce stably and maintain their characteristics across varying environmental conditions.
Innovation Solution
A new Calibrachoa cultivar, 'Suncalkuki', developed through planned breeding, exhibiting a trailing habit, moderately vigorous growth, freely branching and flowering, long flowering period, and yellow-colored flowers, achieved through cross-pollination of proprietary selections and stabilized via asexual reproduction by vegetative cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cross-pollination breeding is conducted to develop new Calibrachoa cultivars with unique flower coloration, then flower color variety and plant habit characteristics are improved, but stability of reproduction and consistency of traits across generations face challenges
Solution Approach 1:
The patent applies parameter changes by systematically varying breeding parameters including selecting specific parent plants with desired traits (trailing habit, flower color), controlling pollination conditions, and selecting progeny with optimal combinations of characteristics. This approach enabled the development of 'Suncalkuki' with stable yellow flower coloration and trailing habit that reproduce true to type across generations
Solution Approach 2:
The patent employs copying through asexual reproduction methods such as vegetative propagation to create genetically identical copies of the selected Calibrachoa plant. This ensures that the unique combination of traits in 'Suncalkuki' (yellow flowers, trailing habit, branching pattern) is precisely replicated in subsequent generations, maintaining reproduction stability and trait consistency
2Shape
If selection for trailing plant habit and free branching is emphasized, then plant form and growth pattern are improved, but flowering period length and vigor may be compromised
Solution Approach 1:
The patent applies merging by combining multiple desirable traits from different parent plants into a single cultivar. The breeding program integrated trailing habit, free branching, and extended flowering period from various parental selections to create 'Suncalkuki,' which exhibits all three characteristics simultaneously without compromise
3Ease of manufacture
If intense selection for unique flower coloration is applied, then color distinctiveness is improved, but genetic diversity and adaptability to environmental variations may be reduced
Solution Approach 1:
The patent applies local quality by focusing selection on specific local characteristics (flower color, plant habit) while maintaining overall plant health and adaptability. The breeding program targeted unique yellow flower coloration in 'Suncalkuki' without compromising the plant's ability to adapt to environmental conditions, achieving both color distinctiveness and environmental tolerance
