Caladium Candyland Cultivar Breeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new and distinct cultivar of Caladium that exhibits specific traits such as compact, upright growth and unique leaf coloration, which are not adequately met by existing cultivars like Lance Whorton and Gingerland, and Florida Sweetheart.
Innovation Solution
The development of the Caladium cultivar 'Candyland' through cross-pollination between Caladium×hortulanum cultivars Lance Whorton and Gingerland, resulting in a plant with compact, bushy growth, strap-like leaves with green, red, and white colors, and specific leaf characteristics that distinguish it from its parents and other cultivars like Florida Sweetheart.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If cross-pollination between cultivars Lance Whorton and Gingerland is performed, then unique leaf coloration (green, red, and white) and compact growth are achieved, but the complexity of the breeding process increases
Solution Approach 1:
The patent uses controlled cross-pollination as an intermediary process between two parent cultivars (Lance Whorton and Gingerland) to produce the desired traits in the offspring. The breeding process acts as a mediator that combines genetic material from both parents to achieve the unique green, red, and white leaf coloration and compact growth habit of Candyland, resolving the contradiction by systematically managing the complexity through controlled hybridization.
2Volume of moving object
If plants are selected for compact, upright growth habit, then space efficiency is improved, but growth vigor may be reduced
Solution Approach 1:
The patent achieves compact plant size with maintained vigor by changing the genetic parameters through selective breeding. The Candyland cultivar exhibits a compact, upright growth habit with a height of about 15-20 cm and spread of 10-15 cm, while simultaneously maintaining vigorous, dense, and bushy growth. This resolves the contradiction by optimizing the balance between plant size and growth vigor through controlled cross-pollination and selection of specific genetic combinations.
3Adaptability or versatility
If multiple unique traits are combined in one cultivar, then the cultivar's distinctiveness is improved, but the difficulty of breeding and stabilization increases
Solution Approach 1:
The patent applies preliminary action by first establishing pure lines of parent cultivars (Lance Whorton and Gingerland) with specific desired traits, then performing controlled cross-pollination to combine these traits. The breeding process systematically combines compact growth, upright habit, strap-like leaves, and unique green, red, and white coloration. Through asexual reproduction by tuber divisions, the cultivar's stability is confirmed, resolving the contradiction by preliminarily preparing parent lines and systematically combining multiple distinct traits.
