Petunia Cultivar Sunsurf Pidami Double-Flower Genetics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Petunia cultivars lack semi-trailing and mounding plants with large, attractive double-type flowers that offer a long flowering period and good garden performance under varying environmental conditions.
Innovation Solution
A new Petunia×hybrida cultivar, 'Sunsurf Pidami', resulting from a cross-pollination between proprietary selections Px858-01 and Px2812-01, exhibiting a semi-trailing and mounding habit, vigorous growth, freely branching and flowering, large purplish pink double-type flowers, and good garden performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If conventional Petunia cultivars are used, then they have simple single-type flowers, but they lack large attractive double-type flowers with long flowering period
Solution Approach 1:
The patent applies parameter changes by crossing Petunia cultivars with different floral characteristics to transform the flower type from single to double-type. The cross-pollination between Petunia cultivar A (single-type flowers) and Petunia cultivar B (double-type flowers) produces offspring with stabilized double-type flowers, achieving both the desired flower shape and extended flowering period through genetic parameter modification.
2Shape
If Petunia cultivars with large double-type flowers are developed, then flower size and attractiveness improve, but plant growth vigor and branching may be reduced
Solution Approach 1:
The patent applies local quality by selecting and stabilizing specific traits in different parts of the plant. The new Petunia cultivar exhibits vigorous growth habit and freely branching characteristics in the vegetative parts while simultaneously producing large double-type flowers in the reproductive parts. This localized optimization allows the plant to maintain both productive growth and large flower development without compromise.
3Shape
If new Petunia cultivars are created through cross-pollination, then flower characteristics improve, but stability and true-to-type reproduction may be compromised
Solution Approach 1:
The patent applies preliminary action by conducting multiple generations of selection and asexual reproduction to stabilize the new Petunia cultivar before commercial release. The inventor performed cross-pollination, then systematically selected plants exhibiting the desired double-type flower characteristics over several generations. Asexual reproduction methods were employed to propagate and stabilize the cultivar, ensuring true-to-type reproduction while maintaining the improved flower characteristics.
