Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing soybean cultivars lack improved traits such as higher seed yield, disease resistance, drought tolerance, and altered fatty acid profiles, which are essential for enhancing agricultural productivity and nutritional value.
Innovation Solution
Development of a new soybean cultivar (26121416) with specific genetic modifications and breeding techniques to introduce desirable traits like herbicide tolerance, disease resistance, and altered fatty acid composition, combined with advanced molecular biology methods for genetic transformation and introgression of transgenic traits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional breeding methods are used to develop new soybean cultivars, then genetic diversity can be maintained, but the development process takes 6-12 years and requires multiple crossing generations
Solution Approach 1:
The patent applies preliminary action by pre-selecting parental lines with desired traits (herbicide tolerance, disease resistance, fatty acid composition) and performing molecular marker analysis before crossing. This advance preparation and selection process reduces the time required for subsequent breeding generations while ensuring genetic stability is maintained through careful parental selection.
2Adaptability or versatility
If multiple crossing generations are performed to combine desirable traits, then trait combination improves, but the breeding process becomes more complex and resource-intensive
Solution Approach 1:
The patent implements feedback through molecular marker-assisted selection during the breeding process. By using DNA markers to track inheritance of desired traits (herbicide tolerance, disease resistance, fatty acid composition), breeders can monitor progress in each generation and make informed decisions about which plants to advance, reducing the number of crossing generations needed while maintaining effective trait combination.
3Productivity
If conventional breeding is used to improve seed yield and nutritional value, then gradual improvement is achieved, but the rate of improvement is limited by natural genetic variation
Solution Approach 1:
The patent applies parameter changes by selecting parental lines with extreme or superior values for key parameters (seed yield, oil content, fatty acid composition, disease resistance) and using molecular markers to track these quantitative traits through generations. This targeted selection based on specific parameter optimization accelerates improvement rates compared to conventional breeding while maintaining genetic stability through controlled crossing.
