Innovation Solution
The introduction of soybean variety 5PPAN44, which is self-pollinated to ensure homozygosity and phenotypic stability, along with methods for crossing, introgressing transgenic or mutant traits, and characterizing the variety to produce stable, high-yielding soybeans with improved agronomic characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional soybean variety development methods are used, then multiple desirable traits can be combined, but the process takes six to twelve years and is time-consuming
Solution Approach 1:
The patent applies preliminary action by pre-selecting and characterizing parent lines with specific desirable traits before crossing. The breeder's goal is to combine improved combinations of desirable traits through planned crosses between pre-characterized parents, reducing the time needed for trait discovery and selection during the breeding process.
Solution Approach 2:
The patent implements feedback through systematic evaluation and characterization of breeding lines at multiple stages. The variety is evaluated for yield, disease resistance, and other traits across different environments, with data fed back into selection decisions to guide further breeding steps and ensure the combination of desirable traits is achieved efficiently.
2Reliability
If traditional breeding methods are used, then stable varieties can be developed, but the process requires extensive resources and is inefficient
Solution Approach 1:
The patent applies segmentation by dividing the breeding process into distinct, manageable stages: parent line selection, crossing, F1 evaluation, and variety development. Each stage has specific objectives and evaluation criteria, allowing for systematic progression and efficient resource allocation while maintaining variety stability through controlled breeding steps.
Solution Approach 2:
The patent utilizes parameter changes by evaluating breeding lines under different environmental conditions and measuring multiple traits (yield, disease resistance, maturity). This multi-parameter approach ensures stable variety development by selecting lines that perform consistently across varying parameters, while the systematic measurement approach improves breeding efficiency.
3Adaptability or versatility
If multiple crosses and selections are performed to achieve high yield and resistance, then desirable traits are combined, but the directionality and planning precision are compromised
Solution Approach 1:
The patent applies preliminary action by establishing clear breeding objectives and selecting parent lines with specific desirable traits before initiating crosses. The breeder's goal is to combine improved combinations of desirable traits through planned crosses between pre-characterized parents, ensuring breeding directionality is maintained throughout the process.
Solution Approach 2:
The patent implements feedback through systematic evaluation of breeding lines for yield, disease resistance, and other traits. This feedback mechanism ensures that selection decisions align with breeding objectives, maintaining directionality while achieving the combination of desirable traits through data-driven selection at each breeding stage.
