Verbena Poena Cultivar Deep Rose Flowering and Growth Habit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new cultivar of Verbena×hybrida that exhibits distinct characteristics such as deep rose flower color, early flowering, and a spreading habit, which are not adequately met by existing Verbena varieties.
Innovation Solution
A new cultivar 'Poena' of Verbena×hybrida, resulting from the open pollination of 'F0132-1' and an unknown parent, characterized by deep rose flowers, early flowering, and a semi-erect then spreading growth habit, has been developed and asexually reproduced, retaining its unique traits through successive propagations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If existing Verbena varieties are used, then common flowering characteristics are achieved, but distinct deep rose flower color and early flowering are not realized
Solution Approach 1:
The patent applies parameter changes by selecting and combining specific genetic parameters from parent plants to achieve deep rose flower color and early flowering. The breeder modified flower color parameters through controlled pollination of 'F0132-1' (scarlet flowering) with an unknown parent, resulting in the distinct deep rose coloration that is not present in conventional varieties.
Solution Approach 2:
The patent demonstrates preliminary action through the planned breeding program conducted in Enkhuizen, Netherlands, where the cross between 'F0132-1' and the unknown parent was deliberately arranged before flowering. This preliminary genetic combination ensured that the deep rose color and early flowering traits would be established in the F1 generation, allowing for controlled propagation through cuttings.
2Shape
If semi-erect then spreading growth habit is developed, then aesthetic appeal is improved, but control over plant morphology becomes more difficult
Solution Approach 1:
The patent applies dynamics by capturing a growth habit that transitions from semi-erect to spreading as the plant matures. This dynamic morphological change provides aesthetic appeal throughout the growing season, with the plant initially displaying upright growth and later developing spreading characteristics, effectively utilizing the temporal dimension of growth control.
Solution Approach 2:
The patent demonstrates local quality through the development of different growth characteristics in different parts of the plant. The semi-erect to spreading transition occurs specifically in the upper portions of the plant, while the base remains more controlled, allowing for localized morphological differentiation that enhances overall aesthetic appeal without requiring complete control of every plant aspect.
3Loss of time
If early flowering is achieved, then season extension is improved, but plant maturity requirements become more stringent
Solution Approach 1:
The patent applies parameter changes by modifying the flowering time parameter through selective breeding. The cross between 'F0132-1' and the unknown parent resulted in an F1 generation that flowers significantly earlier than conventional Verbena varieties, extending the seasonal bloom period while maintaining reliable maturity through controlled genetic parameters.
Solution Approach 2:
The patent demonstrates copying through the asexual propagation of the F1 generation via cuttings. This copying process allows the early flowering trait to be faithfully reproduced in subsequent generations without the variability introduced by sexual reproduction, ensuring consistent maturity and flowering time while maintaining the distinctive deep rose coloration.
