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 01067639, 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 desired 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 new soybean varieties, then genetic diversity is increased, but the process requires extensive research efforts and time due to complexity of genetic combinations
Solution Approach 1:
The patent applies preliminary action by pre-selecting parental lines with desired traits (herbicide tolerance, disease resistance, yield characteristics) before initiating the breeding program. This preliminary selection of parents with known, stable traits reduces the time required for subsequent breeding steps while maintaining genetic diversity through controlled crosses between these pre-characterized lines.
2Adaptability or versatility
If multiple traits are combined in a single variety, then agronomic quality is improved, but the genetic complexity increases making trait prediction difficult
Solution Approach 1:
The patent segments the breeding process into distinct phases: first developing parental lines with individual desired traits (herbicide tolerance, disease resistance separately), then combining them through controlled crosses. This segmentation allows each trait to be optimized independently before combination, reducing the overall genetic complexity while achieving multi-trait varieties with improved agronomic quality.
Solution Approach 2:
The patent applies local quality by introducing specific traits at particular genetic loci while maintaining the original variety's background genome. Through backcrossing and selection, desired traits (herbicide tolerance, disease resistance) are incorporated at specific locations without disrupting other important agronomic characteristics, allowing predictable trait expression in the final variety.
3Productivity
If genetic transformation is used to introduce desired traits, then breeding efficiency is improved, but the variety stability may be affected
Solution Approach 1:
The patent uses conventional crossing and backcrossing as intermediary steps between genetic transformation and final variety stabilization. Transformed plants serve as initial parents that are then crossed with elite lines and subjected to multiple generations of backcrossing and selection. This intermediary process allows the transformed traits to be integrated into a stable genetic background, maintaining variety stability while achieving breeding efficiency.
