Caladium 'Burning Heart' Breeding for Uniform Habit and Color
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new Caladium plant cultivars with uniform plant habit, exceptional container and garden performance, and unique leaf coloration that can reproduce stably and consistently across different environmental conditions.
Innovation Solution
The development of Caladium×hortulanum 'Burning Heart' through cross-pollination between Caladium×hortulanum 'Red Flash' and 'Twist N Shout', which exhibits an intermediate height, vigorous growth, and distinctive bronze and salmon orange leaf coloration, differing from its parents and other cultivars, achieved through asexual reproduction by 'chipping' tubers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If cross-pollination breeding is performed to create new Caladium cultivars with unique leaf coloration, then leaf color diversity and attractiveness are improved, but plant height and growth uniformity may become inconsistent
Solution Approach 1:
The patent applies parameter changes by selecting specific genetic combinations from cross-pollination that result in intermediate plant height (20-30 inches) while maintaining unique bronze and salmon orange leaf coloration. The breeding process optimizes genetic parameters to achieve both color uniqueness and height consistency.
2Productivity
If rapid growth rate is achieved through selective breeding, then time to marketability is reduced, but plant uniformity and habit consistency may be compromised
Solution Approach 1:
The patent achieves rapid growth while maintaining uniformity by selecting for specific growth parameters. The new cultivar exhibits vigorous growth with intermediate height characteristics, reaching marketable size faster than parent cultivars while maintaining consistent plant habit through selective breeding for uniform genetic expression.
3Reliability
If asexual reproduction by tuber chipping is used to propagate the cultivar, then genetic stability and trait consistency are improved, but propagation speed and time to production may be reduced
Solution Approach 1:
The patent uses tuber segmentation (chipping) as a propagation method where tubers are divided into segments, each containing an axillary bud and cortical tissue. This segmentation approach ensures each segment develops into a complete plant with stable genetic traits, balancing propagation efficiency with genetic fidelity.
