Trailing Viola Cultivar with Rounded Flowers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new trailing Viola×wittrockiana cultivars with unique ornamental characteristics for commercial purposes, as existing varieties lack distinct features such as compact growth habit, large rounded flowers, and specific flower colors.
Innovation Solution
The cultivar 'KERVIOCHEEKY' was developed through planned breeding, combining traits like compact trailing habit, large uniquely rounded flowers, and bright yellow with dark blotch flower color, achieved through asexual reproduction by vegetative cuttings, which are stable across generations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If traditional Viola×williamsii varieties are used for trailing plants, then the plant exhibits spreading habit, but the flower shape is elongated rather than rounded
Solution Approach 1:
The patent merges two previously separate traits into one cultivar: the rounded flower shape typically found in Viola×wittrockiana and the trailing growth habit characteristic of Viola×williamsii. This combination was achieved through systematic breeding programs that crossed different Viola species, resulting in 'KERVIOCHEEKY' which simultaneously exhibits both the rounded pansy-type flowers and the compact trailing habit desired for container cultivation.
2Shape
If Viola×wittrockiana is used for flower production, then large rounded flowers are produced, but the plant habit is not compact enough for small containers
Solution Approach 1:
The patent applies local quality by differentiating between the characteristics of the flowering portion and the vegetative portion of the plant. The flowering stems and inflorescences maintain the large rounded flower shape characteristic of Viola×wittrockiana, while the vegetative growth habit is controlled to be compact and trailing, suitable for container cultivation. This is achieved through selective breeding that independently optimizes these different plant regions.
3Adaptability or versatility
If new cultivars are developed through breeding, then unique ornamental characteristics are achieved, but the breeding process requires significant time and resources
Solution Approach 1:
The patent employs preliminary action through the use of planned breeding programs that pre-select parent plants with desired traits before crossing. The parent lines were carefully chosen and characterized in advance, with known traits for flower shape, color, and growth habit. This preliminary characterization and selection of parent material accelerates the breeding process by reducing the need for extensive screening of offspring, as the desired traits are more likely to be inherited from the pre-selected parents.

AI summary
A new and distinct Viola×wittrockiana cultivar named ‘KERVIOCHEEKY’ is disclosed, characterized by a unique combination of a large, round “pansy” type flower, found on a trailing plant. Flower color is a bright Yellow with a Brown to Greyed-Purple blotch, flowers have a wavy petal margin. Plants have a compact, trailing plant habit. The new variety is a Viola×wittrockiana, suitable for outdoor landscape and container use.
