Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current soybean breeding methods face challenges in developing stable, high-yielding varieties with desirable traits such as disease resistance, drought tolerance, and improved nutritional quality, as they rely on conventional breeding techniques that are time-consuming and unpredictable, and often result in varied genetic combinations that are difficult to predict.
Innovation Solution
The development of the soybean variety 01051871, which includes a single locus conversion that can confer traits like herbicide resistance, disease resistance, and improved nutritional quality, achieved through genetic transformation and backcrossing techniques, allowing for precise introduction of desired genes while maintaining the morphological and physiological characteristics of the original variety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional breeding techniques are used, then genetic diversity is achieved, but breeding time and unpredictability increase
Solution Approach 1:
The patent applies preliminary action by pre-selecting parental lines with desired traits (disease resistance, yield, quality) before crossing. The breeding program systematically evaluates parent plants for specific characteristics and prepares breeding populations in advance, reducing the time needed for random selection and multiple generations of selection.
Solution Approach 2:
The patent implements feedback mechanisms through systematic evaluation and selection processes. Breeders assess intermediate generations for desired traits, use molecular markers to track genetic progress, and adjust breeding strategies based on performance data, thereby reducing unpredictability and accelerating the breeding process.
2Adaptability or versatility
If conventional breeding techniques are used, then trait combination is achieved, but prediction accuracy decreases
Solution Approach 1:
The patent uses feedback through molecular marker analysis and performance evaluation to monitor genetic progress at each breeding stage. This allows breeders to predict the likelihood of achieving desired trait combinations with greater accuracy, selecting the most promising lines for advancement.
Solution Approach 2:
The patent replaces traditional mechanical/phenotypic selection with molecular marker-assisted selection. By using DNA markers linked to desired traits, breeders can predict trait inheritance with higher precision without waiting for phenotypic expression, thereby improving prediction accuracy for trait combinations.
3Manufacturing precision
If single locus conversion is used, then breeding precision is improved, but genetic stability may be compromised
Solution Approach 1:
The patent applies local quality by introducing specific desirable traits (single locus conversions) into an otherwise stable elite genetic background. This allows precise modification of specific characteristics (e.g., disease resistance, herbicide tolerance) while maintaining the proven performance and stability of the parental variety's genome.
Solution Approach 2:
The patent uses preliminary action through backcrossing to recover the parental genome. By repeatedly crossing the converted line back to the original variety and selecting for the parental genome, the patent ensures that the final line has >95% genetic identity to the parent, thereby maintaining genetic stability while incorporating the desired conversion.
