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 not efficiently combined in a single variety.
Innovation Solution
The development of the soybean variety 01068821, which includes a single locus conversion conferring traits like herbicide resistance, disease resistance, and improved nutritional quality, achieved through genetic transformation and backcrossing techniques, allowing for the integration of desirable genes into the soybean genome.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional breeding methods are used to develop soybean varieties, then basic agronomic traits are maintained, but multiple improved traits (disease resistance, drought tolerance, herbicide resistance) cannot be efficiently combined in a single variety
Solution Approach 1:
The patent applies genetic transformation technology to directly modify the genetic parameters of soybean varieties, introducing multiple improved traits (disease resistance, drought tolerance, herbicide resistance) simultaneously through genetic engineering rather than traditional sequential breeding methods
Solution Approach 2:
The patent creates composite genetic structures by combining multiple transgenic events and traits within a single soybean variety, effectively creating a 'composite' variety that integrates diverse improved characteristics from different parental lines and genetic sources
2Reliability
If multiple traits are introduced through genetic transformation, then agronomic quality and resistance traits are improved, but the complexity of the breeding process increases
Solution Approach 1:
The patent divides the complex breeding process into distinct stages: initial cross-breeding to establish base variety, followed by sequential genetic transformation events, and final trait integration through backcrossing. This segmentation allows systematic introduction and stabilization of multiple traits without overwhelming complexity
Solution Approach 2:
The patent performs preliminary genetic transformations and trait integrations during the breeding stages before final variety release. By pre-establishing resistance genes and traits in intermediate breeding lines, the final variety inherits stabilized traits without requiring complex post-development modifications
3Adaptability or versatility
If backcrossing techniques are used to integrate desirable genes, then trait combination is improved, but the time required for variety development increases
Solution Approach 1:
The patent maintains continuous breeding cycles with overlapping generations, performing genetic transformations and backcrossing operations in parallel where possible. This continuous action approach reduces idle time between breeding stages and accelerates the overall variety development timeline while maintaining thorough trait integration
