Solution Overview
Problem
Current soybean breeding methods face challenges in developing stable, high-yielding varieties with improved traits such as disease resistance, herbicide tolerance, and nutritional quality, which are difficult to predict and require extensive research efforts due to the complexity of genetic combinations and environmental factors.
Innovation Solution
The development of the soybean variety 01064026, which includes specific genetic loci conferring traits like herbicide resistance, disease resistance, and improved nutritional quality, achieved through a combination of traditional breeding techniques and genetic transformation, allowing for the introduction of desirable traits while maintaining the overall morphological and physiological characteristics of the soybean.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional breeding techniques are used to develop soybean varieties with improved traits, then genetic diversity and trait combinations can be explored, but the process requires extensive research efforts and time due to the complexity of genetic combinations and environmental factors
Solution Approach 1:
The patent applies preliminary action by pre-selecting parental lines with desired traits (herbicide resistance, disease resistance, nutritional quality) before crossing. The breeding program systematically identifies and combines specific genetic loci in advance, reducing the time needed for random screening and evaluation of numerous genetic combinations.
Solution Approach 2:
The patent changes the parameter of trait prediction accuracy by using molecular markers and genomic selection to predict offspring traits before phenotypic expression. This allows breeders to select desirable genetic combinations earlier in the breeding process, significantly reducing the time required for field testing and evaluation across multiple generations.
2Productivity
If multiple traits are combined in a single soybean variety to achieve high yield and improved quality, then the agronomic performance and nutritional value are enhanced, but the genetic complexity and difficulty of stable inheritance increase
Solution Approach 1:
The patent segments the complex trait combination process into distinct genetic loci that can be independently tracked and combined. Each desirable trait (herbicide resistance, disease resistance, oil composition) is associated with specific genetic markers that can be selected for individually, then combined in a systematic breeding program to achieve stable multi-trait varieties.
Solution Approach 2:
The patent employs feedback through molecular marker-assisted selection, where DNA markers linked to desired traits are used to monitor and select for the presence of specific genetic loci during breeding. This feedback mechanism ensures that multiple traits are stably inherited and combined in the desired proportions, reducing genetic complexity management while maintaining high productivity.
3Ease of manufacture
If genetic transformation is used to introduce specific traits such as herbicide resistance, then the trait introduction becomes more precise and efficient, but the overall morphological and physiological characteristics must be carefully maintained
Solution Approach 1:
The patent applies local quality by introducing specific genetic traits (herbicide resistance, disease resistance) at localized genetic loci through transformation or targeted breeding, while maintaining the overall genomic background and morphological characteristics of the parental lines. This allows precise trait introduction without disrupting the plant's overall physiological integrity.
Solution Approach 2:
The patent uses copying by selecting parental lines with stable and desirable morphological and physiological characteristics, then replicating these characteristics in the transformed or bred progeny. Molecular markers are used to ensure that the genomic regions controlling important agronomic traits are conserved and copied accurately from the parental lines to the improved varieties.
