Dianthus KLEDP17262 Mutation Breeding for Upright Habit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new and distinct variety of Dianthus caryophyllus that exhibits unique red-purple flowers with lighter red-purple borders and an upright habit, which is not met by existing varieties.
Innovation Solution
A new variety, 'KLEDP17262', is developed through a whole plant mutation from 'KLEDP14206' (Oscar 'Purple Wings'), characterized by red-purple flowers with lighter red-purple borders and an upright habit, propagated via vegetative stem cuttings, maintaining its traits in successive generations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a new Dianthus variety is developed through mutation to achieve unique red-purple flowers with lighter borders and upright habit, then flower color and plant form are improved, but breeding time and complexity increase
Solution Approach 1:
The patent applies preliminary action by establishing a systematic mutation breeding program that pre-selects for desired traits. The breeder intentionally induces mutations and maintains multiple generations of plants with specific characteristics (upright habit, red-purple flowers with lighter borders) before commercial release, rather than waiting for random mutations to occur naturally in production fields.
Solution Approach 2:
The patent applies parameter changes by inducing genetic mutations that alter specific plant parameters - particularly flower color ( achieving red-purple with lighter borders) and plant architecture (upright habit). These parameter changes are achieved through controlled mutation breeding followed by selection of plants exhibiting the desired phenotypic changes.
2Stability of the object's composition
If vegetative propagation is used to maintain true-to-type reproduction, then genetic consistency is improved, but propagation speed and rooting efficiency may be limited
Solution Approach 1:
The patent applies copying through vegetative propagation methods where new plants are created as genetic copies of the parent plant. Stem cuttings are taken from mother plants and rooted to produce clones that identicaly reproduce the desired traits (flower color, plant form). This ensures genetic consistency while enabling multiplication of the improved variety.
3Shape
If selection for specific flower color and habit is implemented, then ornamental value is improved, but selection criteria and evaluation complexity increase
Solution Approach 1:
The patent applies local quality by focusing selection on specific local characteristics of the plant - particularly the flower color (red-purple with lighter borders) and the upright growth habit. Rather than evaluating all plant traits equally, the breeder concentrates selection pressure on these specific local qualities that provide ornamental value, making the selection process more targeted and efficient.
