Regpin Geranium Cultivar Eliminating Cooling Treatment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Regal Geranium cultivars require cooling treatments for flower development, limiting their early flowering capabilities and uniformity under varying environmental conditions.
Innovation Solution
A new cultivar, 'Regpin', developed through planned breeding in Dresden, Germany, exhibits an upright, vigorously growing, freely branching habit with large bi-colored pink and dark purple flowers, and does not require cooling treatments for flowering, showcasing enhanced vigor and uniformity compared to parent selections and similar cultivars like 'Regdar'.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cooling treatment is applied for flower development, then flower development is promoted, but flowering time is delayed and process complexity increases
Solution Approach 1:
The patent extracts and eliminates the requirement for cooling treatment from the flower development process. The new cultivar 'Regpin' naturally initiates and develops flowers without requiring the external cooling stimulus that conventional Regal Geranium cultivars need, thereby removing this process step entirely.
Solution Approach 2:
The patent changes the physiological parameters of the plant through breeding to alter its flowering response. The new cultivar has modified sensitivity to temperature cues and flowering initiation thresholds, allowing it to flower reliably without the cooling treatment that conventional varieties require.
2Reliability
If cooling treatment is applied for flower development, then flower initiation is promoted, but cultivation complexity increases
Solution Approach 1:
The patent removes the cooling treatment step from the cultivation process entirely. The new cultivar 'Regpin' initiates flowers under normal greenhouse conditions without requiring the additional equipment, space, or management procedures associated with providing cooling treatments.
Solution Approach 2:
The new cultivar performs self-service regarding flower initiation by using its own metabolic processes and responding to standard environmental conditions to trigger flowering, rather than requiring external intervention through cooling treatments.
3Adaptability or versatility
If conventional breeding is used, then genetic diversity is maintained, but uniformity and vigor are reduced
Solution Approach 1:
The patent combines multiple parent selections through controlled cross-pollination to create a new cultivar that merges desirable traits. The resulting 'Regpin' cultivar shows heterosis (hybrid vigor) with improved uniformity, vigor, and flower characteristics compared to the parents, while maintaining the genetic diversity achieved through the breeding process.
