Senecio Cultivar Breeding for Compact, Uniform Plant Architecture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Senecio plants lack compact, upright, and uniformly mounded growth habits with freely branching and attractive inflorescences, and there is a need for new cultivars that exhibit unique and attractive floral characteristics.
Innovation Solution
Development of a new Senecio cultivar, 'Sene Isifuro', resulting from a controlled cross-pollination of proprietary selections S12-61-3 and S12-100-2, exhibiting compact, upright growth, vigorous branching, and unique spoon-shaped ray florets with distinct coloration, achieved through asexual reproduction by terminal vegetative cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If existing Senecio plants are used, then they have basic growth habits, but they lack compact, upright, and uniformly mounded growth habits with freely branching and attractive inflorescences
Solution Approach 1:
The patent applies parameter changes by selecting and breeding plants with specific growth parameters (compactness, upright habit, uniform mounding) to transform the overall plant architecture. The new cultivar 'Sene Isifuro' exhibits these improved parameters through controlled cross-pollination and selection, achieving a consistent compact and upright growth form that differs from the variable habits of existing Senecio plants.
2Shape
If existing Senecio cultivars are used, then they have basic inflorescence characteristics, but they lack unique and attractive floral characteristics with consistent spoon-shaped ray florets
Solution Approach 1:
The patent applies local quality by focusing on the specific shape characteristic of ray florets, creating a consistent spoon-shaped form that distinguishes the new cultivar. This localized trait enhancement in the inflorescence structure, particularly the ray floret morphology with dark violet upper surfaces and light violet lower surfaces, provides a reliable and attractive floral characteristic that is consistently reproduced across generations.
3Reliability
If asexual reproduction by terminal vegetative cuttings is used, then the unique features are stable and reproduced true to type, but the breeding process requires controlled environment and time
Solution Approach 1:
The patent applies preliminary action by establishing the desired traits through controlled cross-pollination and selection before mass propagation. The new cultivar 'Sene Isifuro' was developed through preliminary breeding work (cross-pollination in March 2013, selection in February 2016) to establish the compact growth habit and spoon-shaped ray florets, ensuring that subsequent asexual reproduction by cuttings will reliably reproduce these pre-established traits without requiring further breeding intervention.
