Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Soybean breeding faces challenges in predicting phenotypic expression due to genetic complexity and environmental factors, making it difficult to reproduce stable, high-yielding varieties consistently.
Innovation Solution
Development of the soybean variety GLL0059, which includes a transgene conferring herbicide resistance and other desirable traits, along with methods for producing hybrid seeds and plants through selfing, backcrosses, and genetic transformation, enabling the creation of regenerable cells for tissue culture and introduction of genes for resistance, nutritional enhancement, and industrial usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional breeding methods are used to develop soybean varieties, then variety diversity can be achieved, but phenotypic expression cannot be predicted due to genetic complexity and environmental factors
Solution Approach 1:
The patent replaces conventional phenotypic selection methods with molecular marker-based genotypic selection. By using DNA markers linked to desirable traits, breeders can directly assess genotype without relying on phenotypic expression, thereby eliminating the unpredictability caused by environmental factors and genetic complexity while maintaining variety diversity.
2Stability of the object's composition
If multiple breeding methods are applied to create stable varieties, then variety stability can be improved, but breeding time and complexity increase
Solution Approach 1:
The patent applies preliminary action by using molecular markers to identify and select plants with desired genotypes early in the breeding process, before phenotypic expression occurs. This allows breeders to make informed selection decisions at the seedling stage rather than waiting for mature plant evaluation, significantly reducing the time required to develop stable varieties while maintaining genetic stability through marker-assisted selection.
3Ease of manufacture
If conventional breeding selection is used, then desirable traits can be selected, but the breeder can only work with phenotype and not directly with genotype
Solution Approach 1:
The patent replaces phenotypic observation with molecular marker analysis, enabling direct genotypic assessment. By using DNA-based markers that are tightly linked to target genes, breeders can directly evaluate genotype information without relying on phenotypic expression, thereby recovering the lost genotype information and improving trait selection accuracy and ease.
