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 XB29AM14, which is the result of careful breeding and selection, combining traits such as resistance to aerial web blight, aphid antibiosis, and improved fatty acid profiles, through a process involving cross-pollination and genetic marker-assisted breeding to ensure uniformity and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional soybean breeding processes are used to combine multiple desirable traits, then disease resistance and yield improvement can be achieved, but the breeding process becomes extremely time-consuming and resource-intensive
Solution Approach 1:
The patent applies preliminary action by using molecular marker technology to pre-identify and select parent lines that carry desired trait genes before actual crossing. This allows breeders to predict offspring characteristics in advance, eliminating the need for lengthy field testing of each generation to assess disease resistance and other traits, thus dramatically reducing breeding time while maintaining reliability
2Productivity
If multiple generations of selection and crossing are performed to achieve stable high-yielding varieties, then agronomic soundness and yield are improved, but the development process requires extensive resources and cannot be changed in direction
Solution Approach 1:
The patent replaces the traditional mechanical/phenotypic selection system with a molecular marker-based selection system. Instead of growing and evaluating multiple generations in the field to assess yield and agronomic traits, breeders use DNA markers to directly identify and select plants with desired genetic combinations, substituting lengthy agricultural processes with rapid laboratory analysis, thereby reducing resource consumption
3Adaptability or versatility
If careful breeding and selection are conducted to combine desirable traits from parental germplasm, then traits like disease resistance and fatty acid profile can be combined, but the process requires precise planning and efficient resource use
Solution Approach 1:
The patent implements feedback by using molecular marker data to continuously monitor and guide the breeding process. Marker information provides real-time feedback on the genetic composition of breeding lines, allowing breeders to make informed decisions about which lines to advance, cross, or discard, thereby simplifying program management while achieving complex multi-trait combinations
