Dahlia Bkdars Cultivar Breeding for Stable Traits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new Dahlia plant cultivars with a freely branching habit, attractive ray floret coloration, long flowering period, and good garden performance, as existing varieties may lack these desirable traits or exhibit variability under different environmental conditions.
Innovation Solution
The Dahlia hybrida cultivar 'Bkdars' is developed through planned breeding, characterized by a compact, upright growth habit, dense foliage, early and continuous flowering, double inflorescences with light purple ray florets, and improved garden performance, distinguishing it from its parent and comparable varieties like 'Gallery Sisley'.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing Dahlia varieties are used, then they may have some desirable traits, but they lack the combination of freely branching habit, attractive ray floret coloration, long flowering period, and good garden performance
Solution Approach 1:
The breeding program segmented the desired traits into specific breeding objectives: freely branching habit, attractive ray floret coloration (light purple), long flowering period, and good garden performance. By selecting and combining these individual traits through systematic breeding, the cultivar 'Bkdars' achieves a reliable combination of all desirable characteristics that existing varieties lack individually or in combination.
2Manufacturing precision
If Dahlia varieties are bred for specific traits, then those traits are improved, but variability may occur under different environmental conditions
Solution Approach 1:
The cultivar 'Bkdars' exhibits self-service characteristics through its inherently stable genotype that automatically maintains consistent trait expression across varying environmental conditions. The plant's genetic constitution naturally ensures reliable flowering period, ray floret coloration, and growth habit without requiring external intervention or controlled environments, demonstrating both trait consistency and environmental adaptability simultaneously.
3Adaptability or versatility
If breeding programs focus on multiple traits simultaneously, then the overall plant performance is improved, but the breeding complexity and time required increase
Solution Approach 1:
The breeding program employed preliminary action by establishing clear breeding objectives and selecting parent plants with complementary traits before initiating the crossing program. The open-pollination of selected parent plants in July 2006 was designed with predetermined goals for freely branching habit, light purple ray florets, and long flowering period. This preliminary planning and selection approach streamlined the breeding process, enabling efficient development of cultivar 'Bkdars' with all desired traits combined without excessive time loss.
