Verbena Cultivar Lan Pursar Compact Habit Branching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a distinct cultivar of Verbena hybrida that exhibits specific traits such as compact growth, vigorous branching, and resistance to Powdery Mildew, which are not adequately met by existing Verbena varieties.
Innovation Solution
The cultivar 'Lan Pursar' is a naturally occurring branch mutation of Verbena hybrida, characterized by a compact, spreading habit, vigorous growth, freely branching and flowering, large purple and white 'star'-patterned flowers, and resistance to Powdery Mildew, achieved through asexual reproduction by vegetative cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If existing Verbena varieties are used, then general growth is achieved, but compact growth habit and vigorous branching are not adequately met
Solution Approach 1:
The patent describes a naturally occurring branch mutation that changes the growth parameters of the Verbena plant, resulting in a compact habit with vigorous branching. The mutation alters fundamental growth characteristics to achieve both compactness and branching vigor simultaneously, resolving the contradiction between these two traits.
2Reliability
If existing Verbena varieties are used, then general flowering is achieved, but resistance to Powdery Mildew is not adequately met
Solution Approach 1:
The new Verbena cultivar exhibits inherent resistance to Powdery Mildew through its genetic composition, allowing it to protect itself from disease without requiring additional interventions. This self-protecting characteristic is integrated into the plant's overall vigor and flowering capability, maintaining high productivity while achieving reliable disease resistance.
3Stability of the object's composition
If asexual reproduction by vegetative cuttings is used, then stable and true-to-type reproduction is achieved, but environmental condition variations may affect phenotype
Solution Approach 1:
The patent acknowledges that while asexual reproduction maintains genetic stability and true-to-type characteristics, the phenotype can vary with environmental conditions such as temperature and light intensity. This parameter change approach recognizes the interaction between genetic stability and environmental influences, accepting phenotypic variation while maintaining genetic fidelity.
