Dahlia Cultivar DATOOGTYVE Strong Stems Container Production
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new Dahlia cultivar with an upright, strong, and healthy growth habit suitable for large-scale container production and with fully double, globular-shaped flower heads of attractive inflorescence color, which existing cultivars do not adequately meet.
Innovation Solution
The development of the Dahlia cultivar 'DATOOGTYVE' through controlled breeding, characterized by stiff and strong lateral stems, thick compound leaves, and composite flower heads with 150 to 200 red-purple ray florets, which reproduces true to type through asexual reproduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If existing Dahlia cultivars are used for container production, then they may have adequate flower size, but they lack upright, strong growth habit suitable for large-scale container production
Solution Approach 1:
The patent applies parameter changes by selectively breeding for specific morphological parameters including stem thickness (1.5-2.5 cm diameter), upright growth habit, and compact plant architecture. These parameter modifications create a cultivar optimized for container production while maintaining strong stems and large flowers.
2Reliability
If Dahlia cultivars produce large flowers, then they have attractive inflorescence, but they may not maintain consistent traits through reproduction
Solution Approach 1:
The patent employs segmentation by separating the breeding process into distinct phases: initial hybridization to combine desirable traits, followed by systematic selection and asexual propagation. This segmented approach ensures trait consistency is established before scaling up production.
Solution Approach 2:
The patent applies preliminary action through controlled hybridization and multi-generation selection before commercial propagation. The cultivar 'DATOOGTYVE' underwent extensive breeding work including crossing 'DA12' with selected pollen parents, followed by rigorous selection of plants exhibiting consistent upright growth, strong stems, and large globular flowers before asexual reproduction was initiated.
3Shape
If Dahlia cultivars have spreading growth habit, then they may fill container space, but they lack the upright, strong structure needed for commercial production
Solution Approach 1:
The patent modifies the plant architecture parameter by selecting for upright growth habit with limited spreading, compact basal branching, and strong vertical stems. This creates an optimized plant shape that fills containers efficiently while maintaining structural integrity for commercial handling and display.

AI summary
A new distinct cultivar of Dahlia plant named ‘DATOOGTYVE’, characterized by its upright to slightly spreading shape, with stiff and strong lateral stems and thick compound leaves, with up to 7 leaflets. The color of the mature leaves are RHS Yellow-green 147A (upper side) and RHS Grayed-green 191A (Underside). Compound leaves are 8-24 cm in length, and 8-18 cm in width. Only a few single leaves are present. Composite flower heads are 9-11 cm in diameter, with a large number of ray florets (about 150 to 200). The ray florets are RHS Red-purple 61A or RHS Red-purple 71A.
