Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sweet corn breeding methods fail to produce stable, high-yielding hybrids with improved agronomic, horticultural, and eating qualities, as well as enhanced resistance to diseases and environmental stresses.
Innovation Solution
Development of a hybrid sweet corn plant designated AIRLIE, which can be propagated vegetatively and genetically modified to incorporate traits such as male sterility, herbicide resistance, disease resistance, and improved nutritional quality, using methods like backcrossing and genome editing techniques.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional sweet corn breeding methods are used, then existing varieties can be maintained, but stable high-yielding hybrids with improved agronomic, horticultural, and eating qualities cannot be produced
Solution Approach 1:
The breeding program segments the development process into distinct phases: creating inbred lines through multiple generations of self-pollination, then crossing these inbreds to produce F1 hybrids. This segmentation allows for systematic improvement of yield stability by first establishing genetically uniform lines and then combining them in controlled crosses.
Solution Approach 2:
The patent applies preliminary action by developing and stabilizing inbred parental lines before creating the final hybrid varieties. Multiple generations of self-pollination and selection are performed in advance to establish pure lines with desirable traits, ensuring that the subsequent F1 hybrids inherit stable, high-yielding characteristics.
2Object-affected harmful factors
If conventional breeding methods are used, then existing varieties can be maintained, but resistance to diseases and environmental stresses cannot be enhanced
Solution Approach 1:
The patent merges multiple breeding objectives into a unified program where disease resistance, stress tolerance, and high yield are simultaneously pursued. Inbred lines are developed that combine multiple resistance traits, and these lines are then crossed to produce F1 hybrids that inherit and express all desired resistance characteristics.
Solution Approach 2:
Inbred lines serve as intermediary elements that carry and stabilize multiple resistance genes before being used to create final hybrid varieties. These inbreds act as mediators that consolidate genetic material for disease and stress resistance, making the breeding program more efficient and less complex than direct hybrid development.
3Adaptability or versatility
If genetic modification techniques are applied, then traits like male sterility and herbicide resistance can be incorporated, but manufacturing and regulatory complexity increases
Solution Approach 1:
The patent replaces conventional mechanical breeding operations with genetic modification techniques to introduce specific traits such as male sterility and herbicide resistance. This substitution allows for precise, targeted modification of plant characteristics without requiring complex multi-generation breeding programs for each individual trait.
