Petunia Dopetsuspabu Cultivar Traits and Breeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new compact, freely branching, and early-flowering Petunia plants with attractive flowers that can reproduce stably and maintain their unique characteristics across varying environmental conditions.
Innovation Solution
A new cultivar of Petunia X hybrida, 'Dopetsuspabu', was developed through controlled cross-pollination, exhibiting a compact, upright to hanging habit, moderately vigorous growth, and large reddish purple flowers with random white spots, achieved through asexual reproduction by terminal vegetative cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If traditional Petunia breeding methods are used, then genetic diversity is maintained, but stability of unique traits across generations is compromised
Solution Approach 1:
The patent employs asexual reproduction through terminal vegetative cuttings to create exact genetic copies of the selected Petunia plant. This copying method ensures that the unique traits (compact habit, freely branching structure, early flowering, and flower characteristics) are replicated identically across generations without genetic variation, thereby achieving stability of unique traits while maintaining the genetic composition of the original plant.
2Volume of moving object
If compact plant habit is selected, then space efficiency is improved, but growth vigor may be reduced
Solution Approach 1:
The patent achieves a compact plant habit with reduced volume through selective breeding while simultaneously maintaining moderately vigorous growth. This is accomplished by changing the genetic parameters of the plant through controlled cross-pollination and selection, resulting in a cultivar that occupies less space but still exhibits healthy, vigorous growth characteristics.
3Loss of time
If early flowering is achieved, then time to market is reduced, but flower size or quality may be compromised
Solution Approach 1:
The patent achieves early flowering by changing the genetic parameters related to flowering time through selective breeding. The new Petunia cultivar flowers earlier than many traditional varieties while simultaneously maintaining large flower size (approximately 5 cm diameter) and high quality characteristics including attractive reddish purple coloration with white spots, thus improving time efficiency without compromising flower quality.
4Quantity of substance
If numerous flowers are produced, then aesthetic value is improved, but resource consumption increases
Solution Approach 1:
The patent achieves numerous flower production (typically 5-10 flowers per stem) by optimizing genetic parameters for flower production efficiency. The cultivar is bred to produce multiple flowers simultaneously on each stem, maximizing aesthetic value and visual impact while improving resource utilization efficiency compared to varieties that produce fewer, larger flowers.
