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 face challenges in efficiently combining these traits in a single variety.
Innovation Solution
The development of the soybean variety XR35AN11, which is the result of careful breeding and selection, combining traits such as disease resistance, drought tolerance, and improved agronomic characteristics, achieved through a comprehensive breeding program involving cross-pollination and genetic marker profiling to ensure homozygosity and phenotypic stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional soybean breeding processes are used to combine multiple desirable traits, then the variety achieves improved yield, disease resistance, and drought tolerance, but the breeding process becomes time-consuming and resource-intensive
Solution Approach 1:
The patent applies preliminary action by using molecular marker technology to identify and select plants with desired traits (disease resistance, drought tolerance, yield) at early breeding stages. This allows breeders to predict trait inheritance before actual phenotypic expression, significantly reducing the time required to develop varieties with multiple desirable traits while maintaining reliable disease resistance through marker-assisted selection
2Reliability
If traditional soybean breeding processes are used to combine multiple desirable traits, then the variety achieves improved yield, disease resistance, and drought tolerance, but the breeding process becomes resource-intensive
Solution Approach 1:
The patent implements feedback through molecular marker-assisted selection, where DNA markers provide continuous feedback on the presence of desired traits during the breeding process. This allows breeders to make informed selection decisions at each generation, efficiently combining drought tolerance with other traits while minimizing resource consumption by avoiding unnecessary field trials and phenotypic assessments
3Productivity
If multiple desirable traits are combined into a single soybean variety, then the variety achieves superior agronomic performance, but the breeding program requires precise planning and efficient resource use
Solution Approach 1:
The patent applies segmentation by breaking down the complex breeding program into manageable components: identifying specific molecular markers for each desired trait (yield, disease resistance, drought tolerance), selecting for each trait independently through marker-assisted selection, and then combining these selected lines. This segmented approach simplifies the overall breeding program complexity while achieving superior grain yield through the combination of multiple desirable traits
