Hypericum Seiro Cultivar Breeding for Unique Red Fruit Color
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Hypericum cultivars lack unique and large attractive fruit coloration, limiting their commercial appeal and diversity.
Innovation Solution
Development of the new Hypericum androsaemum cultivar 'Seiro' through controlled breeding, characterized by yellow flowers, large bright red fruit, dark green foliage, and a vigorous upright growth habit, which differs significantly from existing cultivars like 'Excellent Flair' in fruit, leaf, and stem color, as well as inflorescence size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If existing Hypericum cultivars are used, then the plant is readily available and easy to propagate, but the fruit coloration is not unique and large enough to provide strong commercial appeal
Solution Approach 1:
The patent applies parameter changes by selectively breeding for specific phenotypic parameters - large fruit size, bright red coloration, and yellow flower color - to create a cultivar with unique and attractive characteristics that stand out in the market while maintaining ease of propagation through asexual reproduction
2Device complexity
If new cultivars with unique fruit coloration are developed through controlled breeding, then commercial appeal is enhanced, but the development time and breeding complexity increase
Solution Approach 1:
The patent employs preliminary action by establishing a controlled breeding program with selected parent plants before the desired cultivar is achieved. The breeder prepared the breeding population, controlled pollination, and monitored progeny systematically from the outset, which streamlined the development process and reduced overall time compared to unstructured breeding approaches
3Reliability
If asexual reproduction by terminal stem cuttings is used, then true-to-type reproduction is achieved, but the propagation process becomes more labor-intensive
Solution Approach 1:
The patent applies self-service by utilizing the plant's own terminal stem cuttings to produce new plants that are true-to-type. The cutting process leverages the plant's natural regenerative capability, where the terminal bud and associated leaves form a self-contained unit that can root and grow into a genetically identical plant, reducing the need for external intervention while maintaining reliability
