Verbena Duempflapus Compact Habit and Large Flower Breeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new compact and semi-upright Verbena plants with numerous large and attractive flowers, as existing varieties do not meet the desired criteria for compactness, branching, flowering habit, and flower size.
Innovation Solution
A new Verbena cultivar, 'Duempflapus', was developed through planned breeding, combining traits such as compact and semi-upright growth, vigorous and freely branching habits, and large purple flowers, distinct from its parents and comparable varieties like 'Lan Bule', with stable reproduction via terminal cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If existing Verbena varieties are used, then they may have large flowers, but they lack compactness and semi-upright growth habit
Solution Approach 1:
The patent combines desirable traits from different parent plants (compact growth habit from one parent, large flower size from another) to create a new cultivar that integrates both characteristics. The cross-pollination between Verbena hybrida V10-1499-002 and F-22-1209 resulted in offspring that merged the compact semi-upright habit with large flower production.
Solution Approach 2:
The patent modifies specific plant parameters through selective breeding - changing the growth habit parameter to be compact and semi-upright while maintaining or enhancing the flower size parameter. This parameter change is achieved through controlled cross-pollination and selection of desirable traits in the progeny.
2Quantity of substance
If existing Verbena varieties are used, then they may have numerous flowers, but they lack vigorous and freely branching habits
Solution Approach 1:
The patent merges the flowering quantity trait with the branching habit trait through cross-pollination. The resulting cultivar combines numerous flowers with a freely branching habit, creating a stable composition where both traits are inherited together through asexual reproduction by terminal cuttings.
Solution Approach 2:
The patent uses terminal cuttings as a propagation method that creates stable, true-to-type reproductions. This asexual reproduction method ensures that the branching habit and flowering characteristics remain consistent across generations, providing stability without requiring complex genetic inheritance.
3Shape
If compact Verbena plants are developed, then plant habit improves, but flower color may be affected
Solution Approach 1:
The patent applies local quality by maintaining distinct flower color characteristics while developing compact plant habit. The flower color (purple to violet) remains a distinct local trait that is preserved despite the changes in overall plant morphology and compactness achieved through breeding.
