Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Echinacea cultivars lack distinct characteristics such as compact growth, vibrant pink flowers, abundant branching, uniform growth, and fast crop time, which are desirable traits for horticultural applications.
Innovation Solution
Development of a new Echinacea cultivar 'BullEchipur 118' with compact growth, vibrant pink flowers, abundant branching, uniform growth, and fast crop time, achieved through asexual propagation in vitro.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If existing Echinacea cultivars are used, then general growth habits are maintained, but compact growth and uniformity are not achieved
Solution Approach 1:
The patent applies parameter changes by selecting and breeding plants with specific growth parameters (compactness, uniformity, branching density) to transform the overall growth characteristics of the cultivar. The in vitro propagation process also involves parameter optimization for media composition and culture conditions to achieve consistent compact growth.
Solution Approach 2:
The patent applies local quality by focusing on specific local characteristics of the plant (apical dominance, lateral branch density, internode length) to achieve overall compact growth. The selection process targets specific local traits that collectively produce the desired uniform compact appearance.
2Quantity of substance
If existing Echinacea cultivars are used, then flower production occurs, but vibrant pink color and large flower size are not achieved
Solution Approach 1:
The patent applies preliminary action by conducting in vitro multiplication early in the breeding process to generate large numbers of clones from selected parent plants. This allows systematic selection for flower color intensity and size before field trials, streamlining the breeding process despite the complexity of selecting for multiple floral traits.
Solution Approach 2:
The patent applies parameter changes by selecting for specific floral parameters (petal color intensity in the pink spectrum, flower diameter, number of flowers per plant) and propagating plants that exhibit optimal combinations of these parameters.
3Productivity
If existing Echinacea cultivars are used, then flowering occurs, but fast crop time is not achieved
Solution Approach 1:
The patent applies preliminary action by conducting in vitro propagation and pre-hardening of plants before field planting. This preliminary growth phase allows selection for early-flowering genotypes and establishes uniform, vigorous plants that will complete their crop cycle faster in the field.
Solution Approach 2:
The patent applies parameter changes by selecting for physiological parameters associated with rapid development (growth rate, time to first flower, flowering duration) and optimizing cultivation conditions to accelerate these developmental parameters.
4Stability of the object's composition
If existing Echinacea cultivars are used, then propagation occurs, but stable and uniform traits across generations are not maintained
Solution Approach 1:
The patent applies copying by using in vitro propagation to create genetically identical clones of selected parent plants. This cloning process ensures that the desirable traits (compact growth, pink flowers, fast crop time) are copied precisely across generations without genetic variation, maintaining stability while enabling high-volume propagation.
Solution Approach 2:
The patent applies parameter changes by optimizing in vitro propagation parameters (media composition, hormone concentrations, culture conditions) to achieve high propagation rates while maintaining genetic and phenotypic stability across multiple generations of clones.
