Erysimum 'Cdcery1' Cultivar Breeding for Drought Resistance and Color Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Erysimum cultivars lack a combination of large, unique flower colors, compact growth habits, and drought resistance, with many exhibiting fading flower colors and less vigorous growth.
Innovation Solution
The development of the Erysimum 'Cdcery1' cultivar, which features silver-dark green foliage, vivid red flowers that do not fade, large flower and leaf size, strong upright stems, and low maintenance compact growth, achieved through controlled breeding and stable asexual propagation by stem cuttings and tissue culture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing Erysimum cultivars are used, then they have some ornamental value, but they lack a combination of large unique flower colors, compact growth habits, and drought resistance, with many exhibiting fading flower colors and less vigorous growth
Solution Approach 1:
The patent applies parameter changes by selecting and breeding plants with specific genetic traits that confer drought resistance while maintaining flower color stability. The cultivar 'Cdcery1' was developed through controlled breeding to optimize parameters including water use efficiency, flower pigmentation stability, and growth habit, resulting in a plant that resists drought conditions without experiencing color fading.
2Duration of action of moving object
If existing Erysimum cultivars are used, then they provide ornamental value, but they exhibit fading flower colors as they mature
Solution Approach 1:
The patent employs feedback mechanisms in the breeding process by continuously evaluating offspring for both flower color retention and growth vigor. Plants are assessed throughout their development cycle, and those exhibiting both persistent vivid coloration and strong growth are selected for further propagation, creating a feedback loop that reinforces both desired traits simultaneously.
3Area of moving object
If existing Erysimum cultivars are used, then they have some flower size, but they lack large flower and leaf size combined with compact plant habit
Solution Approach 1:
The patent applies local quality by directing genetic expression to specific regions of the plant. The breeding program selected for large flower size and large leaf area while maintaining a compact overall plant architecture, creating localized enhancement of organ size without proportionally increasing total plant height. This results in a cultivar with impressive individual flower and leaf dimensions within a compact growth form.
