Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of new soybean cultivars is a time-consuming process that requires precise planning and efficient resource use, aiming to combine desirable traits such as higher seed yield, disease resistance, drought tolerance, and improved fatty acid profile, while existing methods are limited in achieving these goals efficiently.
Innovation Solution
The introduction of soybean cultivar 06210302, which involves crossing with itself or other cultivars, and methods like mutagenesis or transformation to introduce transgenic or mutant traits, along with tissue culture techniques for regenerating plants with specific characteristics, such as herbicide resistance and improved agronomic traits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional soybean breeding methods are used to combine desirable traits, then genetic diversity and trait combination are improved, but the breeding process becomes extremely time-consuming and resource-intensive
Solution Approach 1:
The patent applies preliminary action by pre-characterizing parental lines for specific desirable traits (herbicide tolerance, disease resistance, fatty acid profile) before crossing. This allows breeders to select parents with known trait combinations, reducing the time needed for screening and evaluation in later generations while ensuring the desired traits are present in the progeny.
Solution Approach 2:
The patent uses molecular markers to copy or track specific trait-associated DNA sequences through generations. By using marker-assisted selection, breeders can identify and select plants carrying desired traits without phenotypic expression, significantly accelerating the breeding process while maintaining trait combination accuracy.
2Stability of the object's composition
If multiple crossing and selection cycles are performed to achieve stable cultivars, then genetic uniformity and stability are improved, but productivity and resource efficiency deteriorate
Solution Approach 1:
The patent replaces mechanical/phenotypic selection methods with molecular marker-based selection. Instead of visually screening thousands of plants for desired traits through multiple generations, breeders use DNA markers to identify and select plants with desired genetic compositions in the early generations, reducing the number of cycles needed to achieve genetic uniformity while increasing breeding productivity.
Solution Approach 2:
The patent changes the selection parameter from phenotypic expression to genotypic identification. By using molecular markers to detect trait-associated DNA sequences, the selection process occurs at the molecular level rather than waiting for phenotypic expression, thereby reducing the time and cycles required to achieve stable, uniform cultivars while maintaining high breeding output.
3Productivity
If focus is placed on improving yield and compositional traits, then agronomic quality is improved, but resistance to diseases and environmental stresses may be compromised
Solution Approach 1:
The patent merges multiple trait selection criteria into a single integrated breeding program. By simultaneously selecting for yield, compositional traits (fatty acid profile), and resistance traits (disease and stress tolerance) using marker-assisted selection, the program maintains balanced improvement across all parameters without compromising any single trait, achieving high productivity while ensuring reliability through combined trait selection.
