Colocasia Cultivar With Compact Growth and High Leaf Count
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Colocasia varieties lack attributes such as vigorous but compact growth, unique leaf colors and textures, and stable asexual propagation, which are desirable for both ornamental and food crop applications.
Innovation Solution
The development of the Colocasia esculenta cultivar 'Hawaiian Luau' through controlled pollination, combining 'Maui Gold' as the male parent and a proprietary breeding line '2001-28' as the female parent, resulting in a plant with dark grey-blue leaves, matte surface, and light yellow-green veins, achieved via huli propagation and tissue culture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional Colocasia varieties are used, then propagation is achieved through traditional methods, but they lack vigorous compact growth, unique leaf colors and textures, and stable asexual propagation
Solution Approach 1:
The patent applies parameter changes by selecting and breeding for specific phenotypic parameters including dark grey-blue leaf color, matte surface texture, light yellow-green veins, and compact growth habit. These parameter changes result in a new cultivar 'Hawaiian Luau' that simultaneously achieves stable propagation and unique aesthetic characteristics not found in existing varieties.
2Productivity
If Colocasia plants are bred for vigorous growth, then plant productivity increases, but plant size may become too large for container use
Solution Approach 1:
The patent applies local quality by creating a cultivar with compact overall plant habit while maintaining vigorous local growth characteristics including high leaf count, prolific basal branching, and rapid development. The plant achieves a balanced form factor suitable for containers with dimensions of 30-45 cm height and 25-35 cm spread, while exhibiting vigorous growth rate and high productivity through multiple basal branches and high leaf count.
3Ease of manufacture
If traditional propagation methods are used, then propagation process is simple, but reproduction may not be true to type across generations
Solution Approach 1:
The patent applies self-service by developing a cultivar that reproduces true to type through self-vegetative propagation without requiring complex intervention. The huli propagation method allows the plant to propagate itself asexually, producing clones that maintain the distinctive dark grey-blue leaf color, matte texture, and compact growth habit across multiple generations, ensuring genetic stability and true-to-type reproduction.

AI summary
A new cultivar of Colocasia plant named ‘Hawaiian Luau’ that is characterized by vigorous but compact plant habit with multiple basal branches giving rise to a high leaf count and a rapidly produced full plant for growing in containers or in the landscape. The leaves of ‘Hawaiian Luau’ are dark grey-blue in color with a matte surface texture. The leaf veins and midrib of ‘Hawaiian Luau’ are light yellow-green in color, is disclosed.
