Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current soybean breeding methods face challenges in developing stable, high-yielding varieties with desirable traits such as disease resistance, drought tolerance, and improved nutritional quality, due to the unpredictability of genetic combinations and the need for extensive research and development efforts.
Innovation Solution
The development of the soybean variety 01046051, which combines improved traits through a specific breeding history and genetic transformation, including the introduction of a transgenic gene for glyphosate tolerance, and the use of advanced breeding techniques like backcrossing and marker-assisted selection to introduce desired traits while maintaining the 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 and trait combination are improved, but the unpredictability of genetic combinations and extensive R&D time are worsened
Solution Approach 1:
The patent applies preliminary action by pre-selecting parental lines with desired traits (high oil content, disease resistance, herbicide tolerance) and using marker-assisted selection to track inheritance of specific genetic markers. This preliminary preparation and selection process reduces the time required for variety development by avoiding random breeding and focusing on predetermined trait combinations.
Solution Approach 2:
The patent employs feedback through marker-assisted selection, where DNA markers are used to monitor and select plants inheriting desired traits at each generation. This feedback mechanism allows breeders to make informed selection decisions early in the breeding process, significantly reducing the time needed to develop stable varieties with predictable trait combinations.
2Productivity
If multiple desirable traits are combined in a single variety, then agronomic quality and yield are improved, but the complexity of breeding program and selection process are worsened
Solution Approach 1:
The patent applies segmentation by dividing the breeding program into distinct modules: selecting parental lines with specific traits, using molecular markers to track individual genetic loci, and combining traits through controlled crosses. This segmentation of the breeding process into manageable steps with specific selection criteria at each stage reduces overall program complexity while achieving multi-trait varieties.
Solution Approach 2:
The patent uses local quality by applying marker-assisted selection at specific genetic loci associated with desired traits (oil content, disease resistance, herbicide tolerance) rather than evaluating entire genomes. This localized approach to trait selection simplifies the breeding program by focusing on key genetic regions while maintaining overall variety quality.
3Adaptability or versatility
If transgenic genes are introduced for herbicide tolerance, then agronomic management flexibility is improved, but the complexity of genetic modification and regulatory approval are worsened
Solution Approach 1:
The patent merges multiple desirable traits including herbicide tolerance, disease resistance, and high oil content into single soybean varieties through controlled crossbreeding and selection. By combining these traits in one variety, the patent reduces the need for separate management practices and simplifies overall agronomic management despite the complexity of introducing transgenic genes.
Solution Approach 2:
The patent applies self-service by developing herbicide-tolerant soybean varieties that enable farmers to use glyphosate for weed control without affecting the crop. This self-protection mechanism reduces the need for additional herbicides and simplifies weed management, offsetting the complexity of genetic transformation through practical agronomic benefits.
