Multi Tropic Red Hibiscus Breeding for Continuous Flowering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Hibiscus rosa-sinensis cultivars lack compact, uniform, and continuously flowering varieties with attractive, long-lasting flowers, and there is a need for new cultivars that offer distinct leaf and flower characteristics.
Innovation Solution
The development of a new cultivar, 'Multi Tropic Red', which is the result of a breeding program aimed at creating compact, uniformly mounding, and freely branching Hibiscus plants with shiny dark green leaves and bright red flowers with darker centers, exhibiting improved flower longevity and distinct characteristics compared to existing cultivars like 'Arionicus' and 'Juno'.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing Hibiscus rosa-sinensis cultivars are used, then they have basic flowering capability, but they lack compact uniform growth, continuous flowering, and long-lasting flowers
Solution Approach 1:
The patent applies parameter changes by selecting and breeding plants with specific genetic parameters that control growth habit, flowering continuity, and flower longevity. The cultivar 'Multi Tropic Red' exhibits changed parameters including compact mounding growth form, continuous flowering capability, and extended flower lifespan compared to parent plants, resulting from selective breeding that modified these biological parameters.
2Adaptability or versatility
If existing Hibiscus rosa-sinensis cultivars are used, then they have basic leaf and flower characteristics, but they lack distinct and attractive features
Solution Approach 1:
The patent applies local quality by developing distinct characteristics in specific parts of the plant: shiny dark green leaves with particular texture, and bright red flowers with darker centers. These localized quality enhancements in leaves and flowers create the distinctive aesthetic appeal of 'Multi Tropic Red' while maintaining overall plant uniformity through vegetative propagation.
Solution Approach 2:
The patent uses vegetative propagation by terminal cuttings to create exact genetic copies of the selected plant, ensuring that the distinctive aesthetic characteristics (shiny dark green leaves, bright red flowers with darker centers) are reproduced true-to-type in successive generations, maintaining both distinctiveness and stability.
3Duration of action of moving object
If the female parent selection GB 2006-0006 is used, then it has basic Hibiscus characteristics, but it produces orange red flowers with shorter longevity
Solution Approach 1:
The patent applies preliminary action by conducting open-pollination breeding in September 2006 and then systematically evaluating the progeny over time. The inventor screened and selected the superior plant in August 2007 that exhibited improved flower longevity and color, before propagating it vegetatively. This preliminary selection and evaluation process identified the optimal genotype that combines long-lasting flowers with desirable aesthetic traits.
