Soybean Variety 90Y40 Multi-Race Phytophthora Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Soybean breeders face challenges in developing stable, high-yielding varieties that are resistant to diseases, insects, and abiotic stresses, with existing breeding processes being time-consuming and resource-intensive, and few varieties exhibiting the desired combination of traits such as multi-race Phytophthora resistance and herbicide tolerance.
Innovation Solution
The development of the soybean variety 90Y40, which is resistant to labeled rates of Roundup herbicides, multi-race Phytophthora, and has excellent harvest standability, combined with a genetic marker profile for identification and potential introgression of new traits through backcrossing or transformation, enabling the creation of soybean plants with enhanced resistance and agronomic qualities.
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 breeding process becomes time-consuming and resource-intensive
Solution Approach 1:
The patent applies preliminary action by pre-characterizing parental lines and identifying key traits before the actual breeding process. The method involves selecting parental lines with desired traits (disease resistance, yield potential, stress tolerance) and pre-determining their genetic compatibility, thereby reducing the time required for subsequent breeding cycles and accelerating variety development.
Solution Approach 2:
The patent implements feedback mechanisms through continuous monitoring and evaluation of breeding progress. The method includes assessing intermediate generations for desired traits and using this information to adjust breeding strategies, select promising lines for advancement, and eliminate unproductive directions, thereby optimizing the breeding timeline and resource allocation.
2Reliability
If multiple traits are combined in a single variety through conventional breeding, then variety performance is improved, but the complexity of the breeding program increases
Solution Approach 1:
The patent applies segmentation by dividing the complex breeding program into manageable modules, each focused on incorporating specific traits (e.g., disease resistance, yield, stress tolerance) through separate selection steps. This modular approach allows breeders to systematically accumulate multiple traits without overwhelming complexity, as each trait can be addressed and stabilized independently before moving to the next trait integration phase.
Solution Approach 2:
The patent implements local quality by applying different selection criteria and evaluation methods to different stages and aspects of the breeding process. Specific traits are evaluated using tailored protocols (e.g., disease resistance through controlled inoculation, yield through harvest data, stress tolerance through environmental screening), allowing optimized selection for each trait while maintaining overall program coherence.
3Stability of the object's composition
If extensive breeding cycles are completed to achieve stable varieties, then variety stability is improved, but the number of potential varieties produced decreases
Solution Approach 1:
The patent applies preliminary action by pre-establishing stable parental lines with fixed genetics and well-characterized traits before initiating new breeding cycles. This allows the actual breeding process to focus only on combining and stabilizing new trait combinations rather than building stability from scratch, thereby reducing the number of cycles needed and increasing the rate at which new stable varieties can be produced.
Solution Approach 2:
The patent implements parameter changes by adjusting breeding cycle duration and intensity based on the specific traits being incorporated and the genetic distance between parental lines. The method involves modifying selection stringency, generation intervals, and evaluation frequencies to optimize the balance between achieving stability and maintaining productivity, allowing faster production of stable varieties for commonly desired traits while maintaining thoroughness for complex trait combinations.
