Petunia Cultivar Petnitbl Trailing Habit and Dark Blue Flowers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new and distinct cultivar of Petunia hybrida that exhibits a unique combination of traits such as a trailing and spreading plant habit, freely branching and flowering, and dark blue, velvet-like single flowers, which are not adequately met by existing Petunia cultivars.
Innovation Solution
The development of the 'Petnitbl' cultivar, resulting from a cross-pollination between proprietary selections 'Y1003' and 'Z4120', which showcases a stable and true-to-type phenotype with characteristics like medium-sized, dark blue, single flowers and a vigorous, spreading growth habit, suitable for hanging baskets and other landscape applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing Petunia cultivars are used, then common traits are achieved, but unique combination of trailing habit, free branching, and dark blue velvet-like flowers is not obtained
Solution Approach 1:
The patent combines multiple desirable traits from different parent plants into a single cultivar. The female parent 'Y1003' contributed trailing habit and dark blue flower color, while the male parent 'Z4120' contributed free branching and flowering characteristics. The resulting cultivar 'Petnitbl' merges these traits into a unified plant that exhibits all four characteristics simultaneously, resolving the contradiction between achieving common traits and obtaining unique trait combinations.
Solution Approach 2:
The patent applies local quality by selecting specific traits from each parent plant rather than taking a uniform approach. The female parent's trailing habit and dark blue coloration were selectively combined with the male parent's free branching pattern and flowering behavior. This selective combination of specific local traits from each parent created a unique cultivar that wouldn't exist through conventional uniform breeding approaches.
2Adaptability or versatility
If cross-pollination breeding is performed, then new trait combinations are achieved, but stability and true-to-type reproduction must be ensured
Solution Approach 1:
The patent employed preliminary action through extensive preliminary breeding work and selection processes. Multiple generations of cross-pollination and selection were performed to stabilize the combined traits before the final cultivar was established. The breeder conducted systematic selection over several years, ensuring that the desired trait combination became fixed and stable in the cultivar 'Petnitbl' before commercial release, thus ensuring true-to-type reproduction.
Solution Approach 2:
The patent utilized feedback mechanisms through continuous observation and evaluation of progeny plants. The breeder monitored the expression of trailing habit, free branching, dark blue coloration, and flowering patterns across generations, using this feedback information to select plants that best exhibited the desired trait combination. This iterative feedback process ensured that the new cultivar stabilized with consistent, true-to-type reproduction of all four key traits.
