Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing soybean cultivars lack improved combinations of desirable 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 26141923 with specific genetic modifications and breeding techniques to introduce 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 soybean breeding methods are used, then cultivar development is achievable, but the process takes 6-12 years and requires significant resources
Solution Approach 1:
The patent employs molecular markers and DNA-based selection methods to identify desirable traits early in the breeding process, allowing breeders to select plants with desired characteristics before traditional phenotypic expression occurs. This preliminary genetic screening accelerates the breeding cycle by eliminating the need to wait for plants to mature and express traits phenotypically.
Solution Approach 2:
The patent replaces traditional mechanical/phenotypic selection methods with molecular biology techniques including DNA extraction, PCR amplification, and marker-assisted selection. This substitution of mechanical breeding approaches with molecular methods significantly reduces the time required to develop new cultivars while maintaining genetic stability.
2Productivity
If existing soybean cultivars are used, then current agricultural practices can be maintained, but seed yield and disease resistance are insufficient
Solution Approach 1:
The patent combines multiple desirable traits from different parental lines into a single cultivar through controlled crossing and selection. Molecular markers are used to track and ensure the simultaneous inheritance of multiple traits including disease resistance genes and yield-related characteristics, merging previously separate trait improvements into one integrated cultivar.
Solution Approach 2:
The patent applies marker-assisted selection to specifically target and enhance particular genetic loci associated with disease resistance and yield, rather than relying on general phenotypic selection. This allows for precise improvement of specific traits while maintaining the overall genetic background and other desirable characteristics of the cultivar.
3Adaptability or versatility
If conventional breeding approaches are used, then simple selection is possible, but improved combinations of desirable traits cannot be achieved
Solution Approach 1:
The patent replaces complex manual phenotypic evaluation and selection processes with automated molecular marker analysis systems. DNA extraction, PCR amplification, and marker detection can be performed in high-throughput formats, allowing simultaneous assessment of multiple traits and individuals, thereby simplifying the overall breeding program management despite the advanced technology involved.
Solution Approach 2:
The patent develops a universal marker-assisted selection system that can simultaneously evaluate multiple traits including disease resistance, yield components, and quality characteristics using the same molecular platform. This multi-functional approach allows breeders to select for improved combinations of desirable traits within a single integrated breeding program rather than requiring separate selection programs for each trait.
