Petunia Cultivar Duepotimpipin Compact Mounding Habit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new compact and early-flowering Petunia plants with unique flower colors and growth habits that can reproduce stably through asexual methods, addressing the limitations of existing Petunia varieties in terms of compactness, flower size, and color variation.
Innovation Solution
A new cultivar of Petunia×hybrida, 'Duepotimpipin', is developed through controlled breeding, exhibiting a compact and mounding habit, moderately vigorous growth, freely branching, early and continuous flowering, and rounded pink and white flowers, differing from parent selections in flower color and size, and showing improved compactness and smaller flowers compared to 'Compact Famous Dark Pink'.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If traditional Petunia breeding methods are used, then flower color and size variation is achieved, but plant compactness and early-flowering traits are not sufficiently improved
Solution Approach 1:
The patent applies parameter changes by selecting and breeding for specific quantitative traits including plant height (15-20 cm), flower diameter (3-4 cm), and time to first flower (6-8 weeks). These parameter specifications directly address the contradiction by defining precise targets for both compactness and early-flowering performance, transforming qualitative breeding goals into measurable quantitative parameters that can be systematically optimized.
2Shape
If larger flowers are produced, then flower size and visual impact are improved, but plant compactness and mounding habit are reduced
Solution Approach 1:
The patent applies local quality by specifying that flowers should be relatively large (3-4 cm diameter) while the overall plant remains compact (15-20 cm height). This principle allows different parts of the plant to have different size characteristics - the flowers are locally enlarged for visual impact while the plant body maintains a compact mounding form, resolving the contradiction between flower size and plant volume.
3Productivity
If vigorous growth habit is selected, then plant productivity and flowering output are improved, but plant compactness and ease of cultivation are reduced
Solution Approach 1:
The patent applies parameter changes by defining a moderate vigor level rather than extreme values. The specifications call for moderate vigor that produces 6-8 weeks to first flower and continuous blooming, rather than extremely vigorous growth. This intermediate parameter selection balances productivity with ease of cultivation, making the plant suitable for both commercial production and home gardening while maintaining compactness.
