Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current soybean breeding methods face challenges in developing stable, high-yielding soybean 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 01052030, which incorporates specific genetic traits through backcrossing and genetic transformation, including transgenic genes for herbicide resistance and dicamba tolerance, to produce plants with consistent morphological and physiological characteristics, and the use of tissue culture methods for regeneration and propagation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional breeding techniques are used to develop soybean varieties, then genetic diversity is achieved, but the breeding process becomes time-consuming and unpredictable
Solution Approach 1:
The patent applies preliminary action by using backcrossing to pre-establish a genetic background that is 95-99% identical to the recurrent parent before introducing specific transgenic traits. This preliminary genetic setup accelerates the breeding process by reducing the number of generations needed to achieve stable, predictable varieties with desired traits.
Solution Approach 2:
The patent applies local quality by introducing specific transgenic loci (herbicide resistance, dicamba tolerance) into an otherwise uniform genetic background through backcrossing. This allows precise localization of genetic modifications while maintaining the superior agronomic traits of the recurrent parent, achieving both genetic diversity where needed and uniformity where desired.
2Adaptability or versatility
If conventional breeding techniques are used to develop soybean varieties, then natural genetic combinations are achieved, but the results are difficult to predict
Solution Approach 1:
The patent applies parameter changes by controlling the genetic composition parameters through backcrossing to achieve a specific identity percentage (95-99%) between the developed variety and the recurrent parent. This quantitative control over genetic similarity enables predictable outcomes while maintaining essential genetic diversity for trait expression.
Solution Approach 2:
The patent uses the recurrent parent variety as an intermediary genetic background that mediates between the donor parent's desirable traits and the breeding goals. Through repeated backcrossing to this intermediary, the method achieves predictable integration of specific traits while maintaining the recurrent parent's superior agronomic characteristics.
3Adaptability or versatility
If multiple breeding objectives are combined in a single variety, then comprehensive improvement is achieved, but the complexity of selection and development increases
Solution Approach 1:
The patent applies merging by combining multiple desirable traits (herbicide resistance, dicamba tolerance, disease resistance, yield characteristics) into a single integrated variety through backcrossing. This consolidates multiple breeding objectives into one unified genetic package, simplifying the selection process while achieving comprehensive improvement.
Solution Approach 2:
The patent applies local quality by introducing specific trait loci at particular genetic locations while maintaining the uniform agronomic background of the recurrent parent. This localized introduction of traits simplifies the breeding program by focusing selection on specific genetic regions rather than managing complexity across the entire genome.
