Impatiens Imtrabastar Cultivar Star Pattern and Trailing Habit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new cultivar of Impatiens walleriana that exhibits a distinct star pattern on large flowers and a flat, spreading growth habit, which is not met by existing cultivars like 'Imtrarose', and requires stable asexual reproduction to maintain its unique characteristics.
Innovation Solution
A new cultivar 'Imtrabastar' is developed through planned breeding, combining the proprietary selections 'T3108-1' and 'T2427-1', characterized by red-purple flowers with a star pattern, a trailing habit, and attractive dark foliage, which is asexually reproduced and maintained through cuttings, resulting in a stable and true-to-type plant with specific growth and flowering traits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a new Impatiens cultivar is developed with large flowers and distinct star pattern, then the aesthetic value and distinctiveness are improved, but the breeding complexity and time required increase
Solution Approach 1:
The patent applies preliminary action by conducting planned breeding programs that pre-select parent plants with desirable traits (large flowers, star pattern, trailing habit) before crossing. The parental selections 'T3108-1' and 'T2427-1' were specifically chosen and prepared in advance to ensure the offspring would inherit the desired characteristics, thereby reducing the time needed for multiple breeding cycles.
2Reliability
If a new cultivar with unique characteristics is created, then the distinctiveness and market value are improved, but the stability of these characteristics during asexual reproduction may be compromised
Solution Approach 1:
The patent applies copying by using asexual reproduction through cuttings to create exact genetic copies of the new cultivar 'Imtrabastar'. This ensures that the unique characteristics (large red-purple flowers with star pattern, trailing habit, dark foliage) are perfectly replicated in all subsequent generations without genetic variation, maintaining 100% stability of the desired traits.
3Quantity of substance
If the plant is made to produce large flowers with distinct patterns, then the ornamental value is improved, but the number of flowers per plant may be reduced
Solution Approach 1:
The patent applies merging by combining multiple desirable traits from different parent lines into a single cultivar. The cross between 'T3108-1' (providing large flowers with star pattern) and 'T2427-1' (providing trailing habit and floriferousness) results in 'Imtrabastar' which simultaneously exhibits large flowers, distinct star pattern, AND high flower production capacity, eliminating the trade-off between flower size and quantity.
4Shape
If the plant is designed with a trailing habit and flat spreading growth type, then the architectural form is improved, but the plant height may be reduced
Solution Approach 1:
The patent applies dimensionality change by shifting the growth orientation from vertical (height) to horizontal (spread). The cultivar 'Imtrabastar' was bred to exhibit a trailing and flat spreading growth habit, where the plant achieves its architectural form through lateral extension rather than vertical growth, creating a ground-covering or hanging plant suitable for baskets and containers.

AI summary
A new Impatiens plant, characterised particularly as to novelty by a flat and strong outward spreading growth habit, freely branching with branches that tend to grow horizontally, resulting in a big and floriferous plant with large red-purple flowers with a distinct white star pattern.
