Impatiens Imtrarestar Cultivar Star Pattern Breeding
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 with attractive dark foliage, differing from existing varieties in growth habit and flower color, while being stable across successive generations of asexual reproduction.
Innovation Solution
A new cultivar, 'Imtrarestar', is developed through planned breeding, characterized by its flat and spreading growth habit, carmine flowers with a white star pattern, and dark foliage, resulting from the cross-pollination of proprietary selections 'T3108-2' and 'T2463-1', and has been asexually reproduced in multiple locations to ensure stability and consistency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a new Impatiens cultivar is developed through cross-pollination to achieve distinct star pattern and carmine flower color, then flower appearance and pattern are improved, but breeding time and complexity increase
Solution Approach 1:
The patent applies preliminary action by conducting planned breeding programs that pre-select parent lines with desirable traits (carmine color, star pattern) before cross-pollination. The parent selections 'T3108-2' and 'T2463-1' were specifically chosen and prepared in advance to ensure the desired flower characteristics would be achieved in the offspring, reducing the time needed for multiple breeding cycles.
2Reliability
If the cultivar is asexually reproduced multiple times to ensure stability, then reliability of trait inheritance is improved, but propagation time and effort increase
Solution Approach 1:
The patent applies self-service through asexual reproduction by cuttings, where the plant propagates itself without requiring repeated cross-pollination. Once the stable cultivar 'Imtrarestar' was established, it can be reproduced indefinitely through cuttings that naturally root and grow into identical plants, maintaining trait stability without additional breeding intervention.
3Shape
If the cultivar is designed with trailing habit and large flowers, then aesthetic appeal is improved, but plant size and space requirements increase
Solution Approach 1:
The patent applies dimensionality change by directing the plant's growth horizontally along trailing branches rather than vertically upward. The cultivar 'Imtrarestar' develops a trailing habit where stems grow along the ground or containers, creating a spreading appearance that covers surface area without requiring significant vertical space, thus maintaining aesthetic appeal while adapting to space constraints.

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 carmine flowers with a distinct white star pattern.
