Veronica Atomic Violet Cultivar Disease Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Veronica hybrida cultivars lack distinct characteristics such as large flower size, unique flower color, and robust disease resistance, particularly in comparison to 'Darwin's Blue' and 'Purpleicious', and 'Atomic Pink', which have smaller flowers and lesser rust and mildew resistance.
Innovation Solution
The development of a new Veronica hybrida cultivar, 'Atomic Violet', characterized by dark purple-violet flowers, compact habit, healthy foliage, and superior mildew and rust resistance, achieved through asexual reproduction by vegetative cuttings in a controlled environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional Veronica hybrida cultivars are used, then disease resistance is insufficient, but flower size and color uniqueness are limited
Solution Approach 1:
The patent applies parameter changes by selecting and propagating plants with specific phenotypic parameters (larger flower corolla height and diameter, distinct dark purple-violet coloration, compact habit) to create a cultivar that simultaneously achieves superior disease resistance and improved floral characteristics. The controlled environment propagation ensures these parameters are stabilized and reproduced true to type.
2Stability of the object's composition
If asexual reproduction by vegetative cuttings is used, then true-to-type reproduction is achieved, but the process requires controlled environment
Solution Approach 1:
The patent employs copying through vegetative propagation by cuttings, where new plants are generated as genetic copies of the parent plant. This ensures true-to-type reproduction of the distinctive traits (flower size, color, habit, and disease resistance) while the controlled environment facilitates successful rooting and establishment of these copies.
3Adaptability or versatility
If open pollination is used, then genetic diversity is increased, but selection for specific traits becomes difficult
Solution Approach 1:
The patent applies preliminary action by conducting open pollination in a controlled nursery setting before selection, allowing genetic diversity to be generated in advance. Subsequently, plants are evaluated and selected based on specific traits (flower size, color, disease resistance), and the chosen plants are propagated asexually to preserve the selected characteristics.
