Dahlia Cultivar BKDAMFOB Stable Traits via Cuttings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new Dahlia plant cultivars with sturdy container growth, freely basal branching, and attractive large inflorescences with specific ray floret coloration that can reproduce stably and consistently across varying environmental conditions.
Innovation Solution
The Dahlia hybrida cultivar 'BKDAMFOB' is developed through controlled breeding, exhibiting a broadly upright and bushy growth habit, semi-double inflorescences with yellow orange and orange red ray florets, and is propagated via terminal cuttings, maintaining its unique features across generations.

Engineering Contradiction Analysis
1Volume of moving object
If Dahlia plants are bred for large inflorescences, then the inflorescence size increases, but the plant becomes less suitable for container growth
Solution Approach 1:
The breeding program systematically varied genetic parameters through controlled crosses between selections with different inflorescence size characteristics, selecting for the optimal combination of large inflorescences and compact plant architecture suitable for containers
2Shape
If Dahlia plants are bred for specific ray floret coloration, then the coloration becomes more attractive and distinct, but the genetic stability across generations may be compromised
Solution Approach 1:
The breeding program implemented systematic evaluation and selection feedback loops, where each generation was assessed for both coloration quality and genetic stability, with only those plants demonstrating both traits advancing to the next breeding cycle
Solution Approach 2:
True-to-type reproduction was achieved through asexual propagation by terminal cuttings, which creates genetically identical copies of the selected plant, ensuring that the unique coloration pattern is precisely replicated across generations without genetic variation
3Shape
If Dahlia plants are bred for freely basal branching habit, then the plant becomes bushier and more compact, but the structural complexity increases
Solution Approach 1:
The plant architecture was optimized by promoting branching at the basal region rather than apical dominance, effectively segmenting the plant into multiple compact units that collectively form a dense, manageable structure suitable for containers
