Pentas 99/280-6 Breeding Program for Cold Tolerance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Pentas plant breeding methods are inefficient in producing consistent, superior varieties due to the unpredictability of genetic combinations and the lack of control over environmental factors, leading to high research costs and variability in plant traits.
Innovation Solution
Development of the Pentas clone 99/280-6, which exhibits cold tolerance and unique inflorescence, along with methods for vegetative propagation, crossing, and mutagenesis or transformation to produce plants with desirable traits such as herbicide resistance, insect resistance, and improved horticultural performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional breeding methods are used to develop new Pentas varieties, then genetic diversity is generated through crossing and selfing, but the outcomes are unpredictable and require 8-12 years to complete
Solution Approach 1:
The patent applies preliminary action by establishing a controlled breeding program with predetermined parental selections and systematic evaluation protocols before the breeding process begins. This allows the breeder to plan multiple generations in advance, track specific genetic combinations, and reduce unnecessary trial-and-error cycles, thereby shortening the overall breeding timeline while maintaining genetic diversity goals.
Solution Approach 2:
The patent implements feedback mechanisms through periodic objective evaluation of breeding line performance, comparing advanced lines against established standards at multiple stages. This continuous feedback allows the breeder to identify promising lines earlier, make informed decisions about which lines to advance or discard, and adjust the breeding program accordingly, reducing the time required to develop superior varieties.
2Measurement precision
If replicated evaluations are conducted to accurately assess genetic worth, then measurement precision improves, but resource expenditure and time requirements increase
Solution Approach 1:
The patent applies partial action by conducting replicated evaluations selectively rather than universally across all breeding lines. The breeder focuses intensive evaluation resources on lines showing promise in preliminary screenings, while applying less intensive evaluation to other lines. This approach maintains adequate measurement precision for decision-making while significantly reducing overall resource consumption compared to evaluating every line with the same level of replication.
3Adaptability or versatility
If multiple breeding lines are developed through conventional methods, then trait improvement opportunities increase, but research costs and complexity increase proportionally
Solution Approach 1:
The patent applies segmentation by dividing the breeding program into distinct phases or modules, each with specific objectives and evaluation criteria. Rather than managing all breeding lines simultaneously as a single complex program, the breeder segments the work into manageable components (e.g., initial crossing phase, selection phase, evaluation phase, advancement phase), making the overall program less complex and more controllable while still exploring multiple trait improvement opportunities.
