Hildyna Carnation Cultivar Uniform Plant 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 changing genotype, and do not consistently exhibit desirable traits like vigorous growth, dark red flower color, and large, double flowers.
Innovation Solution
A new Carnation cultivar 'Hildyna' is developed through controlled breeding, characterized by an upright, freely branching, and uniformly mounded habit with large dark red double flowers, offering improved garden performance and stability across generations through asexual reproduction by terminal cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional Carnation cultivars are grown under varying environmental conditions, then phenotype varies, but genotype remains unchanged, resulting in lack of uniformity in plant habit and flower characteristics
Solution Approach 1:
The patent applies parameter changes by selecting and fixing specific genetic parameters through controlled breeding to achieve uniform phenotype expression. The new cultivar 'Hildyna' was developed through systematic breeding programs that selected for stable expression of upright plant habit, freely branching growth pattern, and large dark red double flowers, making these traits consistent across varying environmental conditions while maintaining the plant's ability to adapt.
2Manufacturing precision
If breeding programs aim to create uniform plant habit and numerous unique flowers, then desirable traits are achieved, but breeding complexity and time increase
Solution Approach 1:
The patent employs preliminary action through extensive pre-breeding work and selection of parental lines with desired traits before the final cross. The breeding program systematically evaluated multiple generations, selected superior individuals, and maintained detailed records to streamline the development of cultivar 'Hildyna' with its characteristic upright habit, freely branching growth, and large dark red double flowers, thereby reducing overall program complexity.
3Shape
If Carnation plants are selected for large dark red double flowers, then flower attractiveness increases, but plant vigor and garden performance may be compromised
Solution Approach 1:
The patent applies local quality by optimizing specific local characteristics of the plant - the flowers exhibit large dark red double form with excellent color intensity and petal quality, while the plant simultaneously maintains vigorous upright growth, freely branching habit, and strong adaptability to garden conditions. This localized optimization of flower traits without compromising overall plant health was achieved through careful selection of parental lines and systematic evaluation of progeny.
