Carnation Hilmimi Cultivar Breeding for Compact Growth and Flower Traits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing cultivars of Dianthus caryophyllus, such as 'Orapotse' and 'Hilluigi', lack desirable traits like freely branching habit, smaller leaves, and distinctively colored double flowers with fewer and fainter dark red stripes, which are not consistently reproduced in various environmental conditions.
Innovation Solution
A new cultivar 'Hilmimi' is developed through controlled breeding, exhibiting a uniformly mounding and upright growth habit, relatively small leaves, freely flowering habit, and salmon pink-colored double flowers with fewer and fainter dark red stripes, achieved through asexual reproduction by terminal cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing cultivars like 'Orapotse' and 'Hilluigi' are used, then they have established growth patterns, but they lack desirable traits such as freely branching habit, smaller leaves, and distinctively colored double flowers with fewer and fainter dark red stripes
Solution Approach 1:
The patent applies parameter changes by selectively breeding for specific traits including branching frequency, leaf size, flower petal count, and stripe intensity. The new cultivar 'Hilmimi' exhibits modified parameters compared to parent cultivars: increased branching, reduced leaf size, higher petal count (25-35 petals), and fainter dark red stripes, achieving the desired combination of reliable growth with enhanced desirable characteristics
2Adaptability or versatility
If new traits are introduced through breeding, then desirable characteristics are achieved, but consistency of reproduction across environmental conditions may be compromised
Solution Approach 1:
The patent employs preliminary action through extensive controlled breeding and selection processes conducted before commercial release. The cultivar underwent multiple generations of asexual reproduction by terminal cuttings in controlled greenhouse environments to pre-establish trait consistency. This preliminary stabilization ensures that the new cultivar 'Hilmimi' reliably reproduces its distinctive traits including salmon pink coloration, double flower form, and faint striping across various environmental conditions
3Ease of manufacture
If flower petals have more stripes and darker coloration, then visual impact is enhanced, but the distinctive fainter dark red stripe pattern is lost
Solution Approach 1:
The patent applies local quality by creating a differentiated stripe pattern where the dark red stripes are present but fainter and less prominent than in parent cultivars. The salmon pink background color provides visual impact while the subdued stripes create a distinctive refined appearance. This local modification of stripe intensity and distribution achieves the desired aesthetic precision without sacrificing overall visual appeal
4Length of moving object
If peduncles are longer, then flower display height is increased, but container performance and compactness are reduced
Solution Approach 1:
The patent applies parameter changes by modifying peduncle length to an optimal range of 1.5-2.5 cm, which is shorter than many traditional cultivars. This parameter modification achieves compact container performance while still allowing adequate flower display. The shortened peduncles contribute to the cultivar's suitability for container growth and maintain a compact, mounding plant habit
