Pericallis 'Dosenmapu' Compact Cultivar Breeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new compact Pericallis plants with attractive medium-sized inflorescences that offer distinct characteristics such as compact growth habit, dark green leaves, and specific ray floret colors, which are not adequately met by existing cultivars like Senecio cruentus 'Sunsenedibu'.
Innovation Solution
A new cultivar of Pericallis x hybrida, 'Dosenmapu', is developed through cross-pollination of proprietary selections SN-0328 and SN-0348, exhibiting a compact, broadly upright growth habit, dark green leaves, and medium-sized daisy-type inflorescences with dark purple ray florets, differing from its parents and other cultivars like 'Sunsenedibu' in size, leaf color, and floret characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If existing cultivars like Senecio cruentus 'Sunsenedibu' are used, then they provide flowering characteristics, but they lack compact growth habit and specific ray floret colors
Solution Approach 1:
The patent applies parameter changes by selecting and breeding plants with specific genetic parameters that control growth habit compactness and ray floret color. The new cultivar 'Dosenmapu' exhibits a compact mounded growth habit and dark purple ray florets, representing specific parameter values that were selected through controlled cross-pollination and stabilized through asexual reproduction.
2Area of moving object
If larger inflorescences are developed, then aesthetic appeal is enhanced, but plant size increases reducing compactness
Solution Approach 1:
The patent applies local quality by concentrating the inflorescence development in a compact mounded form rather than allowing dispersed growth. The new cultivar produces numerous medium-sized inflorescences (5-7 cm diameter) that are densely packed within a compact plant framework (23-25 cm height), creating local density in the floral region while maintaining overall plant compactness.
3Ease of manufacture
If dark purple ray florets are selected, then distinct color characteristics are achieved, but genetic diversity may be reduced
Solution Approach 1:
The patent applies copying by using asexual reproduction through vegetative terminal cuttings to replicate the exact genetic makeup of the selected plant with dark purple ray florets. This method produces identical clones that maintain the specific color characteristic (dark purple, closer to 83A) while preserving the complete genetic profile, ensuring both color consistency and genetic stability across generations.
