Mandevilla Sunparacore Breeding for Trait Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new Mandevilla plant cultivars with freely-branching, dark red-colored flowers that exhibit stable and reproducible traits across varying environmental conditions and cultural practices.
Innovation Solution
The development of Mandevilla×amabilis 'Sunparacore' through planned breeding, characterized by a compact, vigorous, and freely branching habit with medium-sized dark red flowers, which maintains its unique features through asexual reproduction by cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If open-pollination breeding is used to create new Mandevilla cultivars, then genetic diversity and novel traits are introduced, but trait stability and reproducibility across generations are compromised
Solution Approach 1:
The patent applies preliminary action by performing controlled open-pollination breeding to generate desired genetic variation, then immediately following with asexual reproduction through cuttings to lock in and stabilize the selected traits. This two-stage approach first introduces genetic diversity through controlled pollination, then ensures trait stability by propagating the selected plant asexually, preventing further genetic recombination.
2Reliability
If asexual reproduction by cuttings is used, then trait stability and reproducibility are maintained, but genetic diversity is reduced
Solution Approach 1:
The patent performs the genetic diversity generation through controlled open-pollination first, then uses asexual reproduction as a follow-up action to stabilize and propagate the selected traits. The preliminary breeding phase creates the genetic variation, and the subsequent cutting propagation phase preserves the desired traits without further genetic change.
3Measurement precision
If controlled greenhouse environment is used for plant discovery and selection, then trait observation and selection accuracy are improved, but environmental adaptability data is limited
Solution Approach 1:
The patent first performs precise plant discovery and selection in a controlled greenhouse environment where conditions can be tightly regulated and observed. This preliminary controlled phase ensures accurate identification of desired traits. The controlled environment serves as a preliminary screening stage before the plants would be deployed in broader environmental conditions.
