Hilprot Carnation Cultivar Uniform Mounded Habit and Flower Traits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Carnation plant cultivars lack uniformity in plant habit and flower characteristics, with variations in environmental conditions affecting phenotype without genotype changes, and existing cultivars do not meet the desired traits of upright, spreading, and freely branching with large, double flowers.
Innovation Solution
The development of a new Carnation cultivar 'Hilprot' through cross-pollination of a proprietary Dianthus caryophyllus selection and 'Margarita', exhibiting stable, uniformly mounded, freely branching, and freely flowering habits with large purple and light pink double flowers, broader leaves, and increased petal count.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If existing Carnation cultivars are used, then they can be grown as potted and garden plants, but they lack uniformity in plant habit and flower characteristics
Solution Approach 1:
The patent applies parameter changes by selecting and stabilizing specific genetic parameters through controlled cross-pollination and asexual reproduction. The cultivar 'Hilprot' was developed by crossing a proprietary selection with 'Margarita', then selecting plants with desired traits (uniform mounded habit, freely branching, large double flowers) and propagating them asexually to fix these parameters genetically, reducing phenotypic variation under environmental conditions.
2Shape
If the plant habit is made upright and spreading, then the plant structure is improved, but the branching habit becomes more complex
Solution Approach 1:
The patent applies local quality by developing a cultivar with differentiated growth patterns in different regions. The plant exhibits upright growth in the central stem region while having outwardly spreading and freely branching lateral branches. This localized differentiation of growth habits creates the desired mounded overall shape while maintaining complex branching where needed for fullness and flower production.
3Shape
If large double flowers with more petals are produced, then the flower characteristics are improved, but the petal count and flower size increase complexity
Solution Approach 1:
The patent applies parameter changes by selectively breeding for increased petal count and specific flower morphology. The cross-pollination between the proprietary selection and 'Margarita' was used to combine genes for large flower size, double flower structure, and specific color patterns (purple with light pink margins). Asexual reproduction then stabilized these floral parameters to produce consistent large double flowers with numerous petals.

AI summary
A new and distinct cultivar of Carnation plant named ‘Hilprot’, characterized by its upright, outwardly spreading and uniformly mounded plant habit; freely branching habit; freely flowering habit; large purple-colored double flowers with light pink-colored margins that are positioned above and beyond the foliar plane on strong peduncles; and good garden performance.
