Veronica Joca128 Plant Cultivar Dwarf Habit White Flowers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new cultivar of Veronica spicata that exhibits a unique combination of characteristics such as a dwarf plant habit, large white inflorescences, and a floriferous blooming habit, which are not adequately represented in existing cultivars like 'Ulster Blue Dwarf', 'Verswhite', and 'Icicle'.
Innovation Solution
The development of the new cultivar 'Joca128', which is derived from 'Ulster Blue Dwarf' and characterized by its dwarf plant habit, large white flowers, and numerous flowering stems, achieved through asexual propagation by softwood cuttings, ensuring stability and reproduction of these traits in successive generations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a new Veronica cultivar is developed with multiple desired traits (dwarf habit, large white flowers, floriferous blooming), then the ornamental value is improved, but the breeding complexity and time required increase
Solution Approach 1:
The patent uses asexual propagation by softwood cuttings to create exact genetic copies of the selected plant 'Joca128'. This copying method preserves all desired traits (dwarf habit, large white flowers, floriferous blooming) without the complexity of repeated hybridization, allowing rapid multiplication of the cultivar while maintaining trait stability across generations.
2Adaptability or versatility
If traditional open-pollinated breeding is used to create new Veronica cultivars, then genetic diversity is improved, but the stability and uniformity of traits in successive generations deteriorate
Solution Approach 1:
The patent performs preliminary selection of the parent plant 'Joca128' with all desired traits before propagation. By selecting a single plant that already possesses the complete combination of dwarf habit, large white flowers, and floriferous blooming, and then propagating it asexually, the method ensures trait stability in successive generations while having already captured the necessary genetic diversity in the parent selection phase.
3Stability of the object's composition
If asexual propagation is used to ensure trait stability, then the uniformity of characteristics is improved, but the genetic diversity and adaptability to new conditions deteriorate
Solution Approach 1:
The patent employs softwood cutting propagation to create uniform clones of 'Joca128', ensuring consistent expression of dwarf habit, large white flowers, and floriferous blooming. The genetic adaptability concern is resolved because the parent plant itself was selected from open-pollinated seeds, already incorporating beneficial genetic variations, which are then perfectly replicated through the copying process.
