Dianthus Variety With Darkening Maroon Blooms and Compact Habit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new and distinct variety of Dianthus that exhibits a unique dark maroon flower color with a defined color transition and a compact plant habit, which are not adequately addressed by existing varieties.
Innovation Solution
The development of a new Dianthus variety, 'WP24 JAP01', which features dark maroon flowers that deepen in color throughout the flowering season and a short plant habit, achieved through open pollination and vegetative propagation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If existing Dianthus varieties are used, then general flowering characteristics are maintained, but unique dark maroon flower color with defined color transition and compact plant habit are not achieved
Solution Approach 1:
The patent applies parameter changes by selecting and propagating a plant with specific genetic traits that result in dark maroon flower color and compact growth habit. The open pollination event between 'JAP 08.01' and an unknown male variety produced offspring with novel color parameters (dark maroon with color progression) and size parameters (short plant habit), which were then fixed through vegetative propagation.
2Adaptability or versatility
If open pollination is used for variety development, then genetic diversity and unique characteristics are achieved, but breeding time and uncertainty are increased
Solution Approach 1:
The patent employs preliminary action by first performing open pollination to generate genetic diversity and identify promising offspring with desired traits (dark maroon color, compact habit). Once a suitable plant 'WP24 JAP01' is identified, vegetative propagation is immediately implemented to fix the traits and eliminate further breeding time, thereby resolving the time uncertainty inherent in open pollination.
Solution Approach 2:
The patent uses copying through vegetative propagation (stem cuttings) to reproduce the selected plant 'WP24 JAP01' exactly. This asexual reproduction method creates genetically identical copies that maintain the unique dark maroon flower color and compact habit without the variability and time loss associated with continued sexual breeding.
3Stability of the object's composition
If vegetative propagation is used, then true-to-type reproduction is achieved, but genetic improvement opportunities are limited
Solution Approach 1:
The patent performs the genetic diversity generation through open pollination first, then selects the best offspring before switching to vegetative propagation. This preliminary genetic exploration phase ensures that the traits being copied are already optimized, combining the benefits of genetic diversity from sexual breeding with the stability of asexual propagation.
