Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current soybean breeding processes are time-consuming and resource-intensive, aiming to develop stable, high-yielding varieties with desirable traits like disease resistance, drought tolerance, and improved fatty acid profiles, but few varieties meet all these criteria effectively.
Innovation Solution
The development of the soybean variety XB39N09, which combines traits such as glyphosate resistance, multi-race Phytophthora resistance, moderate iron deficiency chlorosis tolerance, strong emergence, and excellent harvest standability, achieved through careful breeding and selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional soybean breeding processes are used to develop varieties with multiple desirable traits, then the varieties achieve improved disease resistance, drought tolerance, and fatty acid profiles, but the breeding process becomes time-consuming and resource-intensive
Solution Approach 1:
The patent applies preliminary action by pre-selecting and characterizing parental lines with specific desirable traits (glyphosate resistance, Phytophthora resistance, iron deficiency chlorosis tolerance, strong emergence, and harvest standability) before crossing. This preliminary characterization of parents P1 and P2 allows the breeding program to systematically combine traits without restarting the selection process, thereby reducing overall breeding time while maintaining reliability of disease resistance traits
2Productivity
If multiple traits are combined in a single soybean variety, then the variety achieves superior agronomic performance and yield potential, but the breeding complexity and resource requirements increase
Solution Approach 1:
The patent applies segmentation by dividing the multi-trait breeding objective into separate parental lines, where P1 contributes glyphosate resistance and Phytophthora resistance, while P2 contributes iron deficiency chlorosis tolerance, strong emergence, and harvest standability. This segmentation allows each parent to be optimized for specific traits independently, reducing breeding program complexity while achieving superior productivity through combination in the progeny
Solution Approach 2:
The patent applies merging by combining the segregated traits from parental lines P1 and P2 into a single integrated variety. The crossing program systematically merges glyphosate resistance, Phytophthora resistance, iron deficiency chlorosis tolerance, strong emergence, and harvest standability into one variety, achieving superior agronomic performance and yield potential through trait integration
