Viola Sunvioda Cultivar Compact Growth Stable Flower Color
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new compact Viola cultivars with attractive flower coloration that can reproduce stably and consistently exhibit unique characteristics such as compact growth, branching, and specific flower colors, which existing cultivars fail to provide effectively.
Innovation Solution
The development of a new Viola cultivar 'Sunvioda' through planned breeding, resulting in a compact, freely branching plant with yellow-orange flowers, achieved by crossing proprietary selections of Viola cornuta, which exhibits stable and true-to-type characteristics through vegetative cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing Viola cultivars are used, then they may have certain flower colors or growth habits, but they fail to provide compact growth combined with attractive flower coloration and stable reproduction
Solution Approach 1:
The breeding program systematically varied genetic parameters through controlled cross-pollination between specific parent selections (0V-128-1 and 0V-40-1) to achieve the desired combination of compact growth habit and attractive yellow-orange flower coloration. The selected cultivar 'Sunvioda' represents an optimized parameter set that simultaneously achieves compactness, branching habit, and stable true-to-type reproduction.
2Area of moving object
If larger flowers are bred, then flower size increases, but plant compactness may be compromised
Solution Approach 1:
The cultivar 'Sunvioda' exhibits local quality optimization where the plant maintains a compact overall structure (height approximately 15.4 cm) while producing relatively large flowers (diameter approximately 3.6 cm). This achieves disproportionate flower size relative to plant size, making the flowers prominent without requiring the plant to grow tall.
3Ease of manufacture
If distinct flower coloration is achieved, then attractivity improves, but consistency of color across generations may vary
Solution Approach 1:
The breeding program selected for stable inheritance of flower color characteristics that reproduce true-to-type through vegetative propagation. The yellow-orange coloration (Royal Horticultural Society Colour Chart 23B-23D) is genetically fixed and consistently expressed across generations, eliminating the need for annual re-breeding to maintain color consistency.
