Dahlia Cultivar DATYVE Strong Stems Container Production
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Dahlia cultivars lack an upright, strong, and healthy growth habit suitable for large-scale container production with attractive, fully double flowers, and there is a need for a cultivar that reproduces true to type with specific leaf and flower characteristics.
Innovation Solution
The development of the Dahlia cultivar 'DATYVE' with upright to slightly spreading shape, stiff and strong lateral stems, thick compound leaves, and globular-shaped flower heads with 120-150 ray florets in orange-red and yellow colors, achieved through controlled breeding and asexual reproduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional Dahlia cultivars are used, then they may have certain flower characteristics, but they lack upright, strong, and healthy growth habit suitable for large-scale container production
Solution Approach 1:
The breeding program systematically altered genetic parameters to produce stems with enhanced mechanical strength properties. The new cultivar 'DATYVE' exhibits stiff and strong lateral stems with upright growth habit, representing a parameter change in stem structural properties that enables large-scale container production while maintaining aesthetic quality
Solution Approach 2:
The controlled breeding program was conducted in advance to develop the desired growth habit before commercial production. The cultivar was stabilized through successive generations of asexual reproduction, ensuring the upright, strong growth habit is firmly fixed and retained, allowing immediate deployment in large-scale container production without further development needs
2Shape
If traditional Dahlia cultivars are used, then they may have certain flower characteristics, but they do not produce fully double flowers with globular-shaped flower heads and attractive inflorescence color
Solution Approach 1:
The breeding program targeted specific floral parameters including ray floret number (120-150 per head), color distribution (RHS Orange-red N30B and RHS Yellow 2A near base transitioning to RHS 17C at apex), and overall globular shape. These parameter changes produce consistently high-quality fully double flowers with attractive inflorescence characteristics
Solution Approach 2:
The breeding program utilized systematic observation and selection feedback to refine flower quality. The new cultivar demonstrates consistent globular-shaped flower heads with 120-150 ray florets and specific color patterns across multiple generations, indicating effective feedback mechanisms were employed to stabilize these precise floral characteristics
3Reliability
If new cultivars are developed through breeding, then desirable growth and flower characteristics are achieved, but stability through successive generations must be established
Solution Approach 1:
The breeding program conducted preliminary stabilization work through controlled crosses and multiple generations of asexual reproduction before releasing the cultivar. The combination of characteristics is firmly fixed and retained through successive generations, meaning the time-consuming stabilization process was completed in advance, ensuring immediate reliability upon commercial deployment
Solution Approach 2:
Asexual reproduction by terminal cuttings was used to create identical copies of the selected parent plant, ensuring the new cultivar reproduces true to type. This copying mechanism efficiently propagates the stabilized genetic combination without the variability introduced by sexual reproduction, rapidly establishing reliability across production batches

AI summary
A new distinct cultivar of Dahlia plant named ‘DATYVE’, characterized by its upright to slightly spreading shape, with stiff and strong lateral stems and thick compound leaves, with up to 12 leaflets. The color of the mature leaves are RHS Green 139A (upper side) and RHS Grayed- green 191A (Underside). Compound leaves are 6-24 cm in length, and 8-18 cm in width. Hardly no single leaves are present. Composite flower heads are 9-10 cm in diameter, with a large number of ray florets (about 120 to 150). The ray florets are RHS Orange-red N30B and RHS Yellow 2A near base.
