Petunia Cultivar Sunsurf Bumiusa Compact Habit and Branching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for compact, freely branching, and freely flowering Petunia plants with uniform mounding habit and attractive flower coloration that can perform well in various environmental conditions, as existing cultivars may vary significantly in phenotype due to environmental factors without changing their genotype.
Innovation Solution
A new cultivar of Petunia×hybrida, 'Sunsurf Bumiusa', was developed through controlled cross-pollination, exhibiting compact and uniformly mounding habit, vigorous growth, early and continuous flowering, and vivid violet-colored flowers, which are stable and reproduce true to type through asexual reproduction by terminal cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If existing Petunia cultivars are grown under varying environmental conditions, then their genotype remains stable, but their phenotype varies significantly
Solution Approach 1:
The patent applies parameter changes by selecting and breeding for specific genetic parameters that confer environmental stability. The new cultivar 'Sunsurf Bumiusa' was developed through controlled cross-pollination and subsequent selection of plants that maintained consistent phenotypic characteristics across different environmental conditions. This involved changing the genetic parameters of the parent plants to produce offspring with enhanced phenotypic stability.
2Length of moving object
If Petunia plants are bred for compact size, then plant height is reduced, but flowering frequency may be compromised
Solution Approach 1:
The patent applies local quality by differentiating the characteristics of different parts of the plant. The cultivar 'Sunsurf Bumiusa' exhibits compact overall plant size while maintaining vigorous lateral branching and high flowering frequency. The plant achieves this by concentrating growth resources in lateral branches rather than vertical growth, creating local areas of high productivity (flowering zones) within a compact form.
3Productivity
If Petunia plants are bred for vigorous growth, then plant size increases, but compactness is reduced
Solution Approach 1:
The patent applies dimensionality change by redirecting the vigorous growth energy from the vertical dimension to the horizontal dimension. The cultivar 'Sunsurf Bumiusa' exhibits vigorous growth manifested as dense lateral branching and spreading habit rather than vertical elongation. This creates a compact, mounding form while maintaining high growth vigor through increased lateral branch production and leaf area.
