Hypericum Seihero Cultivar Breeding for Large Red Fruit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Hypericum cultivars lack unique and attractive fruit coloration, with most varieties having small or unremarkable fruit characteristics, limiting their commercial appeal.
Innovation Solution
Development of the new Hypericum androsaemum cultivar 'Seihero' through controlled breeding, characterized by yellow flowers, large 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
1Reliability
If traditional Hypericum cultivars are used, then commercial availability is maintained, but fruit coloration is unattractive and not unique
Solution Approach 1:
The patent applies parameter changes by selectively breeding plants to modify specific traits - achieving large red fruit, yellow flowers, and dark green foliage through controlled changes in genetic parameters rather than using traditional cultivars with fixed characteristics
2Ease of operation
If existing Hypericum cultivars are used, then cultivation simplicity is maintained, but fruit size is small and unremarkable
Solution Approach 1:
The breeding program changed the size parameter of the fruit by selecting and propagating plants that produced larger berries, transforming the small fruit characteristic of existing cultivars into large, prominent fruit while maintaining ease of cultivation
3Ease of manufacture
If new breeding programs are implemented to improve fruit characteristics, then fruit coloration and size improve, but development time and complexity increase
Solution Approach 1:
The patent applies preliminary action by conducting controlled open-pollination breeding programs in advance to develop the desired fruit characteristics before commercial propagation, ensuring that the large red fruit trait is established and stabilized through asexual reproduction before market introduction
