Verbena KLEVP15622 Compact Growth and Flower Traits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new Verbena varieties with distinct and desirable traits such as compact growth habit and specific flower characteristics that are not adequately met by existing Verbena varieties like 'VEAZ0006' (LANAI 'Bright Pink') and the proprietary varieties '60.00.12' and '75.00.12'.
Innovation Solution
The development of a new Verbena×hybrida variety, 'KLEVP15622', which exhibits a compact and upright growth habit, pink flowers with darker eyes, and good tolerance to powdery mildew, achieved through cross-pollination between proprietary varieties '60.00.12' and '75.00.12', and subsequently propagated via vegetative stem cuttings, ensuring reproductive stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If existing Verbena varieties like 'VEAZ0006' are used, then they provide basic flowering characteristics, but they lack compact growth habit and specific flower features such as darker eyes
Solution Approach 1:
The patent combines desirable traits from two different parent varieties: the compact growth habit and upright form from one parent, and the pink flower color with darker eye characteristics from the other parent. This merging of traits through controlled cross-pollination creates a new variety that simultaneously achieves both the compact shape and the specific flower characteristics that were previously unavailable in single varieties.
2Adaptability or versatility
If new traits are introduced through cross-pollination, then desirable characteristics like compact growth and flower features are achieved, but reproductive stability must be ensured
Solution Approach 1:
The patent performs preliminary selection and evaluation of parent plants before cross-pollination, choosing parents with specific desirable traits. After the cross-pollination produces new varieties, preliminary action is also taken in the form of rigorous testing and evaluation of the offspring to ensure they consistently reproduce the desired traits, thereby establishing reproductive stability before commercial propagation.
Solution Approach 2:
Once a stable new variety with desired traits is established through cross-pollination, the patent uses vegetative propagation (stem cuttings) to create identical copies of the parent plant. This asexual reproduction method ensures that all propagated plants are genetically identical clones, guaranteeing reproductive stability and consistent expression of the compact growth habit and flower characteristics across multiple generations.
3Adaptability or versatility
If propagation is achieved through seeds, then genetic diversity is possible, but true-to-type reproduction is difficult to guarantee
Solution Approach 1:
The patent employs vegetative propagation through stem cuttings to create genetically identical copies of the selected parent plant. This asexual reproduction method produces clones that are true-to-type, ensuring that every propagated plant has the exact same genetic makeup and will express the same compact growth habit, branching characteristics, and flower features, thereby guaranteeing trait consistency across large numbers of plants.
4Volume of moving object
If plant size is reduced for compact growth, then space efficiency improves, but overall plant biomass and flower production may be limited
Solution Approach 1:
The patent promotes extensive branching, creating multiple stems and growth points throughout the compact plant structure. This segmentation of the plant into numerous smaller branches and stems allows the plant to maintain a small overall footprint while distributing flower production across many individual flowering sites, thereby achieving both compact size and high flower production capacity.
