Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current pepper breeding techniques face challenges in developing stable, high-yielding pepper hybrids with improved fruit appearance, eating and processing qualities, and agronomic traits, as existing methods struggle to consistently combine desirable parental traits effectively.
Innovation Solution
The development of the hybrid pepper variety SKYHAWK, which includes specific physiological and morphological characteristics, and methods for vegetative propagation, tissue culture, and introduction of desired traits such as disease resistance and improved nutritional quality, using techniques like backcrossing and genome editing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional breeding techniques are used to develop pepper hybrids, then some desirable traits can be combined, but the process is time-consuming and inconsistent in combining multiple desirable parental traits
Solution Approach 1:
The patent employs genome editing technologies (CRISPR/Cas9, TALENs, zinc finger nucleases) to directly modify genetic parameters and introduce desirable traits in a single step, eliminating the need for multiple generations of traditional crossbreeding. This changes the breeding approach from gradual trait accumulation over many generations to precise, targeted genetic modification that achieves the desired trait combination immediately.
2Productivity
If multiple desirable traits are combined through traditional breeding, then fruit quality and yield can be improved, but the process becomes increasingly complex and difficult to control
Solution Approach 1:
The patent replaces the mechanical, trial-and-error process of traditional crossbreeding with precise molecular biology tools. Instead of manually crossing plants and selecting offspring over multiple generations, the invention uses genome editing to directly write the desired genetic information into the plant genome, substituting a controlled biochemical process for an uncontrolled mechanical breeding process.
3Reliability
If conventional breeding methods are used to improve disease resistance, then some resistance can be achieved, but the process is slow and may not provide adequate resistance to emerging diseases
Solution Approach 1:
The patent applies preliminary action by pre-programming disease resistance genes into pepper varieties before they are deployed to farmers. Using genome editing, resistance genes are introduced in advance, allowing the plants to be pre-equipped with defense mechanisms against known and emerging diseases, rather than relying on slow post-deployment breeding programs to respond to disease outbreaks.
