Petunia Duesurstabu Cultivar Breeding for Phenotypic Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new trailing Petunia plants with unique and attractive flowers that exhibit stable and reproducible traits across various environmental conditions and cultural practices, as existing cultivars may vary significantly in phenotype due to environmental factors without genotype changes.
Innovation Solution
A new cultivar, 'Duesurstabu', resulting from a cross-pollination between proprietary selections of Petunia×hybrida, exhibits a mounding and spreading habit, early and freely flowering, with large light pink-colored flowers and red-purple venation, demonstrating stability through asexual reproduction by terminal cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing Petunia cultivars are grown under varying environmental conditions, then their phenotype varies significantly, but their genotype remains unchanged
Solution Approach 1:
The patent selects and stabilizes specific genetic parameters through controlled cross-pollination and multiple generations of selection. The cultivar 'Duesurstabu' exhibits stable phenotypic parameters (flower color, plant habit, flowering time) across varying environmental conditions, achieving adaptability without phenotypic variation by optimizing the genetic parameter combination.
2Ease of manufacture
If a new Petunia cultivar is developed with unique flower characteristics, then it achieves distinctive appearance, but it requires stable reproduction across generations
Solution Approach 1:
The patent performs preliminary selection and stabilization of desired traits through controlled cross-pollination before commercial propagation. The cultivar 'Duesurstabu' was developed by pre-selecting plants with stable light pink flowers, compact growth, and early flowering, then verifying trait stability through asexual reproduction by terminal cuttings before releasing the cultivar.
Solution Approach 2:
The patent uses asexual reproduction by terminal cuttings to create exact genetic copies of the selected plant. This copying method ensures that the unique characteristics (light pink flowers with red-purple venation, compact growth habit) are reproduced true to type across generations, maintaining both distinctiveness and reliability.
3Productivity
If Petunia plants are bred for compact growth and smaller leaves, then they achieve improved garden performance, but they may reduce overall plant size
Solution Approach 1:
The patent applies local quality by optimizing specific plant characteristics (compact growth habit, smaller leaves, shorter internodes) while maintaining or enhancing other properties (flower size, flowering abundance, vigor). The cultivar 'Duesurstabu' has compact overall size with smaller leaves but produces large flowers and exhibits vigorous flowering, achieving superior garden performance through localized trait optimization rather than uniform size reduction.
