Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current pepper breeding methods face challenges in identifying and developing superior pepper varieties with desirable traits such as disease resistance, nutritional quality, and environmental stress tolerance, due to the complexity of inheritance and the masking of true genotypic values by confounding traits and environmental factors.
Innovation Solution
The development of the jalapeno hybrid pepper XHP16841, which can be used in crossing and breeding programs to introduce desirable traits like herbicide tolerance, insect resistance, and enhanced nutritional quality through methods such as backcrossing, mutation breeding, and genetic transformation, utilizing techniques like CRISPR and TALENs for targeted genome editing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional breeding methods are used to identify superior pepper varieties, then breeding process is simplified, but true genotypic values are masked by confounding traits and environmental factors
Solution Approach 1:
Molecular markers serve as intermediaries between visible phenotypic traits and underlying genotypic values. These markers enable direct detection of desirable genetic traits (disease resistance, nutritional quality, stress tolerance) without being confounded by environmental factors or other traits, thus resolving the measurement precision problem while maintaining breeding process simplicity
Solution Approach 2:
The patent replaces traditional mechanical/visual selection methods with molecular-level detection techniques. Instead of observing phenotypic expressions that are masked by environmental factors, breeders use DNA-based molecular markers to directly identify genotypic values, achieving precise trait identification without the limitations of traditional approaches
2Adaptability or versatility
If complex breeding techniques like backcrossing and genetic transformation are employed, then desirable traits such as disease resistance and nutritional quality can be introduced, but breeding process complexity increases
Solution Approach 1:
Molecular markers are developed and validated in advance for specific desirable traits (disease resistance, nutritional quality, stress tolerance). This preliminary action enables breeders to directly select for these traits using simple marker-assisted selection, avoiding the need for complex multi-generation backcrossing or genetic transformation procedures while still achieving the desired trait diversity
Solution Approach 2:
The patent changes the selection parameter from phenotypic observation to genotypic detection. By using molecular markers that detect specific DNA sequences associated with desirable traits, the breeding process achieves high adaptability and trait diversity through simple selection based on marker presence, rather than complex breeding techniques
