Hypericum Alllangano Cultivar Stem Strength Fruit Density
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Hypericum hybrida cultivars lack strong stems and high fruit density, with limited variation in fruit color and shape, which restricts their use as attractive cut-flowers.
Innovation Solution
A new cultivar, 'Alllangano', bred for upright and spreading habit, dark green leaves, high fruit density, and glossy red-purple fruits, achieved through open-pollination and stabilized via vegetative cuttings, offering improved growth and fruit characteristics compared to its parents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If existing Hypericum hybrida cultivars are used, then they can be grown as cut-flowers, but they lack strong stems and high fruit density
Solution Approach 1:
The patent applies parameter changes by selecting and breeding for specific genetic traits that simultaneously improve stem strength and fruit density. The new cultivar 'Alllangano' exhibits these improved parameters through controlled open-pollination breeding, resulting in plants with both stronger stems and higher fruit density compared to existing cultivars.
2Adaptability or versatility
If existing Hypericum hybrida cultivars are used, then they can be grown as cut-flowers, but they have limited variation in fruit color and shape
Solution Approach 1:
The patent applies local quality by developing distinct fruit color and shape characteristics in the new cultivar. The fruits of 'Alllangano' exhibit a specific glossy red-purple color and particular shape that differentiate it from other cultivars, providing unique local qualities that enhance its attractiveness for cut-flower applications.
3Shape
If the female parent selection (KZ05-54-3) is used, then it has certain growth characteristics, but its leaves curl strongly downwards and it has oval-shaped fruits
Solution Approach 1:
The patent applies inversion by reversing the leaf curl characteristic from the female parent. While the female parent KZ05-54-3 has leaves that curl strongly downwards, the new cultivar 'Alllangano' exhibits leaves that curl upwards, representing an inverted trait that distinguishes it from its parent while maintaining other desirable characteristics.
4Strength
If new breeding is conducted to improve stem strength and fruit density, then these traits are enhanced, but the breeding process requires time and controlled environments
Solution Approach 1:
The patent applies preliminary action by conducting controlled open-pollination breeding in a controlled greenhouse environment to establish the desired traits before commercial propagation. The preliminary breeding work was completed in Cuijk, The Netherlands, with the new plant being discovered in September 2010 and subsequently propagated through vegetative cuttings since April 2012, establishing the trait stability before wider dissemination.
