Solution Overview
Problem
Current soybean breeding methods face challenges in developing stable, high-yielding varieties with improved traits such as disease resistance, drought tolerance, and herbicide resistance, 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 01091555, which involves a specific breeding history and genetic modifications, including the introduction of transgenic genes for herbicide resistance and disease tolerance, using techniques like backcrossing and genetic transformation to combine desirable traits into a single locus conversion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional breeding methods are used to combine multiple desirable traits (disease resistance, drought tolerance, herbicide resistance), then the variety stability and yield potential can be improved, but the breeding time and research effort required increase significantly
Solution Approach 1:
The patent applies preliminary action by pre-introducing multiple transgenic traits (glyphosate resistance, dicamba resistance, and disease resistance genes) into the soybean variety during controlled breeding operations. This allows the traits to be combined in advance through backcrossing and selection, rather than requiring extensive field testing of multiple trait combinations over many years. The variety 01091555 was developed with these traits预先 integrated, reducing the time needed for stable variety establishment.
2Adaptability or versatility
If multiple transgenic traits are introduced into a single soybean variety, then the agronomic performance and resistance profiles are improved, but the genetic complexity and difficulty of trait combination increase
Solution Approach 1:
The patent applies merging by combining multiple transgenic traits (glyphosate resistance, dicamba resistance, and disease resistance) into a single soybean variety 01091555. Through backcrossing operations and selective breeding, the patent integrates these separate genetic elements into one unified variety, achieving the desired trait combination while managing genetic complexity through controlled breeding procedures.
Solution Approach 2:
The patent uses backcrossing as an intermediary method to transfer multiple transgenic traits from donor lines into the target variety. The backcrossing process acts as a mediator that gradually introduces and stabilizes multiple genetic traits while maintaining the genetic background of the original variety, thereby managing the complexity of trait combination.
3Productivity
If extensive breeding operations are conducted to achieve high yield and multiple resistances, then the agronomic quality is improved, but the cost and resources required for research and development increase
Solution Approach 1:
The patent applies preliminary action by pre-establishing the genetic foundation for high yield and multiple resistances through controlled transgenic operations and backcrossing. This preliminary genetic engineering and breeding work consolidates the desired traits early in the development process, reducing the need for extensive field trials and resource-intensive research operations in later stages.
