Erysimum Cdcery3 Cultivar Breeding for Compact Habit and Color Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Erysimum cultivars lack consistent large flower size, unique color retention, compact plant habits, and robust winter hardiness, making them less desirable for ornamental landscapes.
Innovation Solution
The development of the new Erysimum cultivar 'Cdcery3' through controlled breeding, which exhibits silverly dark green foliage, vibrant purple flowers with minimal fading, large flower and leaf size, strong stems, compact growth habit, and drought resistance and winter hardiness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing Erysimum cultivars are used, then they can be grown in ornamental landscapes, but they lack consistent large flower size, unique color retention, compact plant habits, and robust winter hardiness
Solution Approach 1:
The patent applies parameter changes by selectively breeding for specific traits including flower color intensity, plant height, branching pattern, and foliage characteristics. The cultivar 'Cdcery3' was developed through controlled crosses and selection to achieve vibrant purple flowers with minimal fading, compact growth habit (34 cm height), and well-branched structure, representing optimized parameter values for ornamental performance
2Shape
If existing Erysimum cultivars are used, then they can be grown in ornamental landscapes, but they lack consistent large flower size
Solution Approach 1:
The patent optimizes flower size and color retention parameters through selective breeding. The cultivar 'Cdcery3' produces large flowers (2.5 cm depth and diameter) with vibrant purple color that exhibits minimal fading, achieving both increased flower size and improved color fastness simultaneously through controlled breeding programs
3Shape
If existing Erysimum cultivars are used, then they can be grown in ornamental landscapes, but they lack compact plant habits
Solution Approach 1:
The patent modifies plant habit parameters by selecting for compact growth (34 cm height, 38 cm spread) with well-branched structure and upright stems. The cultivar 'Cdcery3' maintains this compact form while achieving good winter hardiness in USDA Zones 6-9, resolving the contradiction between compact habit and winter survival through targeted breeding
