Flovelbl Viola Cultivar Breeding for Stable Traits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new Viola cultivars with outwardly spreading habits, large flowers, and attractive flower coloration that can reproduce stably and true to type, as existing cultivars may vary significantly with environmental conditions and lack desired traits like early flowering and long flowering periods.
Innovation Solution
A new Viola cultivar 'Flovelbl' was developed through planned breeding, combining traits such as mounding and spreading plant habit, early and continuous flowering, and large pale violet-colored flowers, achieved by crossing proprietary selections of Viola×williamsii, which are stable and reproduce via vegetative cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing Viola cultivars are used, then they may have some desirable traits, but they vary significantly with environmental conditions and lack stable reproduction
Solution Approach 1:
The patent applies parameter changes by modifying the genetic parameters of Viola through controlled cross-pollination between specific parent plants. The breeding program selected parents with complementary traits and produced offspring with stabilized genetic parameters that maintain consistency across different environmental conditions while reproducing true to type through vegetative cuttings
2Area of moving object
If Viola cultivars with large flowers are developed, then flower size increases, but flowering period may be reduced
Solution Approach 1:
The patent merges multiple desirable traits from different parent plants into a single cultivar. The cross-pollination combined the large flower trait from one parent with the long flowering period trait from another parent, producing 'Flovelbl' that simultaneously exhibits both large flowers (3.2 cm diameter) and extended flowering duration from early spring through summer
3Length of moving object
If Viola cultivars with upright habits are selected, then plant height increases, but spreading ability is reduced
Solution Approach 1:
The patent creates an asymmetric plant habit where the vertical growth is moderated to allow horizontal spreading. The 'Flovelbl' cultivar exhibits a mounding, outwardly spreading habit with freely branching lateral stems that extend horizontally, creating an asymmetric form that optimizes both vertical presence and ground coverage area
