Diascia CODI101 Cultivar Breeding for Uniform Habit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Diascia cultivars lack uniform plant habit and attractive flower colors, with limited breeding success in creating freely-flowering varieties that maintain stability across different environmental conditions.
Innovation Solution
Development of the new Diascia cultivar 'CODI101' through controlled cross-pollination of proprietary selections, resulting in a compact, densely upright plant with blue violet flowers, larger than the female parent and more reddish-colored than the male parent, and distinct from other cultivars like Codiared in flower color.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing Diascia cultivars are bred without controlled cross-pollination programs, then breeding success is limited and variability increases, but implementing controlled cross-pollination requires more time and resources
Solution Approach 1:
The patent applies preliminary action by conducting controlled cross-pollination between specifically selected parent plants (X99.46.1 and X99.46.4) before the breeding process begins. This pre-planned approach with predetermined parent selections and controlled pollination events accelerates the breeding process while ensuring reliable results, producing the uniform and stable CODI101 cultivar within a defined timeframe rather than through indefinite selection.
2Shape
If Diascia cultivars are bred for uniform plant habit and attractive flower colors, then aesthetic quality improves, but genetic stability across environmental conditions becomes difficult to maintain
Solution Approach 1:
The patent applies parameter changes by selectively breeding for specific phenotypic parameters (compact plant habit, blue violet flower color, freely-flowering habit) while maintaining genetic stability. The controlled cross-pollination between parents with complementary traits produced CODI101 with consistent expression of these parameters across different environmental conditions, achieving both aesthetic quality and genetic stability through targeted parameter selection and validation.
3Area of moving object
If flower size is increased beyond female parent selection, then floral attractiveness improves, but plant compactness may be compromised
Solution Approach 1:
The patent applies local quality by differentiating between local flower size characteristics and overall plant compactness. The CODI101 cultivar was bred to have locally enhanced flower size (larger than female parent) while maintaining the overall compact plant habit through controlled breeding. This allows the flowers to be the focal point of size enhancement without compromising the desired compact growth form, achieving both floral attractiveness and plant compactness through targeted local improvement.
