Mimulus Mimapri Cultivar Hybridization Trait Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new cultivar of Mimulus aurantiacus that combines specific desirable traits such as large, orange-red flowers and glossy medium green foliage, which are not adequately met by existing varieties under varying environmental conditions.
Innovation Solution
The development of the Mimulus aurantiacus cultivar 'Mimapri' through controlled hybridization, which inherits traits like upright and tiered plant habit, and fixed characteristics through asexual reproduction, distinguishing it from other varieties like 'Jelly Bean Apricot'.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing Mimulus varieties are used, then they have basic flowering characteristics, but they do not adequately combine large orange-red flowers with glossy medium green foliage and upright habit under varying environmental conditions
Solution Approach 1:
The patent applies preliminary action by performing controlled hybridization before field deployment to pre-establish the desired trait combination. The cross between 'CO126-1' and 'CO134-1' was conducted in a controlled breeding environment to fix the upright habit, large orange-red flowers, and glossy medium green foliage traits before introducing the variety to varying environmental conditions, ensuring trait consistency while maintaining environmental adaptability
2Adaptability or versatility
If hybridization is performed to combine desirable traits, then new trait combinations are achieved, but the traits may not be firmly fixed and retained through successive generations
Solution Approach 1:
The patent performs preliminary selection and stabilization of traits through controlled hybridization in a controlled breeding environment before asexual reproduction. The hybridization between 'CO126-1' and 'CO134-1' was designed to fix specific traits (upright habit, large orange-red flowers, glossy medium green foliage) in the F1 generation, ensuring these traits would be firmly fixed and retained through successive generations of asexual reproduction
Solution Approach 2:
The patent uses asexual reproduction (vegetative propagation) to create exact genetic copies of the selected plant. This copying process ensures that the desired trait combination is precisely replicated in successive generations without genetic variation, maintaining trait stability while preserving the beneficial trait combination achieved through hybridization
