Caladium Flare Plant Breeding for Uniform Habit and Growth Rate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Caladium cultivars lack uniform plant habit, rapid growth rate, and unique leaf coloration, which are desirable for container and garden performance.
Innovation Solution
The development of Caladium×hortulanum 'Flare' through cross-pollination between Caladium×hortulanum 'White Christmas' and 'Rosemary', resulting in a compact, upright plant with shiny lance-type leaves featuring rose red centers and greyed green and pink speckling, and improved growth habits compared to existing cultivars.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional Caladium cultivars are used, then they have established leaf characteristics, but they lack uniform plant habit and rapid growth rate
Solution Approach 1:
The patent applies parameter changes by creating a new cultivar with modified genetic parameters that simultaneously improve growth rate and plant habit uniformity. The cross-breeding program selected for specific traits including compact growth, upright habit, and uniform foliage, resulting in a cultivar that grows 2-3 times faster than conventional cultivars while maintaining consistent plant architecture.
2Ease of manufacture
If existing Caladium cultivars are used, then they have certain leaf coloration, but they lack unique and attractive leaf coloration with uniform distribution
Solution Approach 1:
The patent applies local quality by creating distinct color zones within the leaf structure. The new cultivar exhibits uniform distribution of color pigments with darker green margins transitioning to lighter green centers, and consistent speckling patterns throughout the foliage. This localized color differentiation enhances aesthetic appeal while maintaining overall uniformity across all leaves.
3Shape
If Caladium×hortulanum 'White Christmas' is used as parent, then white-colored leaves with dark green venation are obtained, but compact and upright plant habit is not achieved
Solution Approach 1:
The patent applies merging by combining desirable traits from both parent cultivars. The cross between 'White Christmas' and 'Rosemary' merged the unique leaf coloration and venation patterns from one parent with the compact, upright growth habit from the other, creating a new cultivar that exhibits both attractive foliage and improved plant architecture.
4Productivity
If Caladium×hortulanum 'Rosemary' is used as parent, then darker rose red leaves with mottled borders are obtained, but compact growth habit is not achieved
Solution Approach 1:
The patent applies copying by replicating the desirable compact growth habit trait from the 'Rosemary' parent in the new cultivar. Through selective breeding, the compact, upright plant architecture was copied and stabilized in the offspring, while also incorporating the unique leaf coloration characteristics to create a distinct new variety with both improved growth rate and maintained compactness.
