Solution Overview
Problem
Current soybean breeding methods face challenges in developing stable, high-yielding soybean varieties with improved traits such as disease resistance, herbicide tolerance, and nutritional quality, which are difficult to predict and require extensive research and time due to the complexity of genetic combinations and environmental factors.
Innovation Solution
The development of the soybean variety 01072767, which includes specific genetic modifications and locus conversions for traits like herbicide resistance, disease resistance, and improved nutritional quality, achieved through genetic transformation and backcrossing techniques, allowing for the introduction of desirable traits while maintaining the original variety's morphological and physiological characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional breeding methods are used to develop soybean varieties with improved traits, then genetic diversity and trait combinations can be explored, but the process requires extensive time and resources due to the complexity of genetic combinations and environmental factors
Solution Approach 1:
The patent applies preliminary action by pre-characterizing parental germplasm for specific traits (herbicide tolerance, disease resistance, yield components) before breeding. This allows breeders to select parents with known, verified traits, reducing the time needed for trait evaluation in later generations and accelerating variety development while maintaining genetic diversity.
Solution Approach 2:
The patent changes the parameter of trait prediction accuracy by using detailed phenotypic and genotypic characterization of parental lines. This enables more reliable prediction of progeny performance, reducing the number of generations needed for selection and thereby decreasing overall breeding time while maintaining adaptability.
2Productivity
If multiple traits are combined in a single soybean variety to improve yield and resistance, then the agronomic quality and productivity increase, but the breeding complexity and difficulty of selecting superior combinations increase
Solution Approach 1:
The patent segments the breeding program into distinct phases: parental characterization, hybridization, progeny evaluation, and variety registration. Each phase focuses on specific traits (e.g., parental lines are characterized for herbicide tolerance, disease resistance, and yield components separately), making the complex multi-trait breeding process more manageable and systematic.
Solution Approach 2:
The patent applies local quality by selecting parental germplasm with specific, localized trait strengths (e.g., one parent excels in herbicide tolerance, another in disease resistance). This allows the breeder to combine complementary traits from specialized parents, achieving high productivity without overwhelming complexity in the breeding program.
3Measurement precision
If extensive phenotypic and genotypic characterization is performed on parental germplasm to predict progeny performance, then the accuracy of trait prediction improves, but the initial research and analysis requirements increase
Solution Approach 1:
The patent performs preliminary phenotypic and genotypic characterization of parental germplasm before breeding operations. This upfront investment in measurement (evaluating yield components, disease resistance, herbicide tolerance) creates a knowledge base that improves prediction accuracy for progeny, reducing the need for extensive testing in later generations and balancing the research input requirement.
