Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current crop breeding methods face challenges in developing uniform and stable bean varieties with desirable traits such as high yield, disease resistance, and uniform pod characteristics, often resulting in unpredictable performance due to genetic non-uniformity in hybrid plants.
Innovation Solution
The development of the bean line RS 08061277, which is a uniform and stable variety achieved through pedigree selection and genetic manipulation, including backcrossing and genetic transformation, to introduce traits like herbicide tolerance and disease resistance, ensuring consistent performance across generations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cross-pollination between different plant varieties is used, then genetic diversity and trait combination are improved, but genetic non-uniformity and performance predictability deteriorate
Solution Approach 1:
The breeding program segments the plant population into distinct homozygous inbred lines through multiple generations of self-pollination and selection. This segmentation creates uniform genetic backgrounds that can be reliably crossed to produce consistent F1 hybrids with predictable performance, while still allowing combination of desirable traits from different lines.
Solution Approach 2:
The patent emphasizes developing homozygous inbred lines that are genetically uniform and homogeneous. These uniform lines produce consistent F1 hybrids when crossed, eliminating the genetic non-uniformity that causes unpredictable performance. The homogeneity is achieved through multiple generations of self-pollination and selection for desired traits.
2Stability of the object's composition
If self-pollination over many generations is used, then genetic uniformity and breeding stability are improved, but breeding flexibility and trait combination capability deteriorate
Solution Approach 1:
The breeding program performs preliminary self-pollination and selection over multiple generations to create a library of homozygous inbred lines with different desirable traits. This preliminary action establishes genetically uniform lines that are stable and predictable, while the diversity is pre-established in the pool of inbred lines available for future crossing programs.
Solution Approach 2:
The patent develops a universal breeding system where homozygous inbred lines serve as stable genetic foundations that can be crossed together or with other lines to produce F1 hybrids. This multi-functional approach allows the same inbred line infrastructure to support various breeding objectives and trait combinations, maintaining both stability and flexibility.
3Reliability
If pedigree breeding and recurrent selection are used, then inbred line development is improved, but breeding complexity and time required deteriorate
Solution Approach 1:
The patent employs self-pollination as a self-service mechanism where the plant naturally pollinates itself, eliminating the need for complex人工 pollination systems. This self-service approach simplifies the breeding process while maintaining genetic uniformity in the inbred lines, reducing both operational complexity and time requirements compared to manual crossing programs.
