Portulaca DPAZ17 Cultivar Large White Flowers Compact Habit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new Portulaca varieties with improved ornamental characteristics for commercial applications, specifically larger flowers and a more compact growth habit, which existing varieties do not adequately address.
Innovation Solution
The development of the Portulaca cultivar 'DPAZ17' through open pollination, characterized by large flowers, a compact and dense semi-trailing habit, and extended flower opening hours, which are stable through asexual reproduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If existing Portulaca varieties are used for ornamental applications, then they provide basic flowering characteristics, but they have small flowers and spreading growth habit which are not desirable
Solution Approach 1:
The patent applies parameter changes by selecting and breeding plants with specific genetic traits that result in larger flower size and compact growth habit. The cultivar 'DPAZ17' exhibits these altered parameters compared to existing varieties, achieving the desired ornamental characteristics through controlled breeding programs that modify plant morphology parameters.
2Duration of action of moving object
If existing Portulaca varieties are used, then they provide basic ornamental value, but their flowers remain closed for shorter duration
Solution Approach 1:
The patent applies preliminary action through selective breeding programs conducted before commercial deployment. The inventor performed controlled crossings and selected seedlings exhibiting the desired trait of extended flower opening duration, thereby preparing the cultivar with pre-established genetic characteristics that ensure prolonged floral display in commercial applications.
3Adaptability or versatility
If open pollination is used to create new varieties, then genetic diversity is introduced, but the pollen parent remains unidentified making breeding tracking difficult
Solution Approach 1:
The patent applies copying by maintaining detailed breeding records and propagating selected seedlings through vegetative cuttings to preserve and replicate the desired traits. This allows the cultivar to be reproduced true-to-type while maintaining the genetic diversity achieved through open pollination, effectively copying the successful genetic combination without needing to identify the original pollen parent.
