Dianthus Breeding for Maculated Pink Flowers and Upright Form
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new and distinct varieties of Dianthus plants that exhibit unique floral and plant form characteristics, such as pink flowers with a maculated pattern and an upright, round plant form, which are not currently available in existing varieties.
Innovation Solution
The development of a new Dianthus variety, 'KLEDA26818', which is derived from a cross between 'DSA-2024-3W503' and an unknown male parent, featuring pink flowers with a maculated pattern and an upright, round plant form, achieved through asexual propagation by stem cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If open cross pollination is used to create new varieties, then genetic diversity and unique characteristics are achieved, but breeding time and complexity increase
Solution Approach 1:
The patent applies preliminary action by performing open cross pollination during specific seasons (May-August 2015) to pre-establish the genetic combination before formal variety development. This preliminary breeding action allows the unique maculated pattern and upright round form to emerge naturally, reducing subsequent breeding time while maintaining genetic diversity.
2Reliability
If asexual propagation by stem cuttings is used, then true-to-type reproduction is achieved, but propagation time and root establishment requirements increase
Solution Approach 1:
The patent applies copying through asexual propagation by stem cuttings, where the new variety 'KLEDA26818' is reproduced exactly as the parent plant. This method creates identical genetic copies that maintain the distinctive pink maculated flowers and upright round plant form, ensuring true-to-type reproduction while establishing a reliable propagation system for commercial production.
3Shape
If unique floral patterns like maculation are developed, then visual distinctiveness is improved, but breeding complexity and selection difficulty increase
Solution Approach 1:
The patent applies local quality by focusing on the specific maculated pattern characteristic of the flowers - the concentrated coloration in specific areas creates the distinctive visual effect. This localized color concentration in the petals provides clear selection criteria during breeding, reducing complexity by focusing on this specific local trait rather than requiring control of multiple flower characteristics simultaneously.
