Bean Line SVGW1212 for Uniform Trait-Stable Breeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bean breeding methods struggle to produce uniform varieties with desirable traits such as high yield, resistance to insects or pathogens, and improved agronomic quality, as they often result in unpredictable genetic diversity and non-uniform populations.
Innovation Solution
Development of the bean line SVGW1212, which is homozygous and uniform, allowing for the introduction of heritable traits like herbicide tolerance, insect resistance, and modified carbohydrate metabolism through genetic engineering, and the use of breeding techniques like backcrossing and marker-assisted selection to maintain desired characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional breeding methods are used to combine desirable traits, then genetic diversity is increased, but uniformity and predictability of performance deteriorate
Solution Approach 1:
The breeding program segments the combination of desirable traits into separate homozygous inbred lines, each line being uniformly purebred for specific traits. This segmentation allows precise control over which traits are combined in which lines, achieving both genetic diversity across lines and uniformity within each line.
Solution Approach 2:
The patent changes the genetic parameter from heterozygous mixed populations to homozygous inbred lines through multiple generations of self-pollination and selection. This parameter change transforms the population from non-uniform to uniform, enabling predictable performance while maintaining trait combinations.
2Manufacturing precision
If self-pollination and selection are performed over many generations to create homozygous plants, then uniformity is improved, but breeding time and complexity increase
Solution Approach 1:
The patent performs preliminary action by creating homozygous inbred lines before the actual breeding program. These pre-prepared uniform lines serve as stable genetic foundations that can be crossed to produce uniform F1 hybrids, eliminating the need to spend multiple generations achieving uniformity during the breeding process itself.
Solution Approach 2:
The patent uses copying by producing multiple copies of homozygous inbred lines that are genetically identical and uniformly purebred. These copies can be replicated across different environments and used consistently, reducing the time needed to develop new varieties since the uniform genetic background is already established.
3Adaptability or versatility
If cross-pollination between different genotypes is performed, then genetic variation is increased, but population uniformity deteriorates
Solution Approach 1:
The patent segments the genetic variation into distinct homozygous inbred lines, each representing a specific genetic combination. When these segmented lines are crossed, the variation is maintained in the F1 generation while each line's uniformity ensures predictable and uniform performance across the population.
Solution Approach 2:
The patent applies local quality by making different parts of the genetic composition have different properties - specific homozygous inbred lines are developed for specific local traits or characteristics. This allows each line to have optimized local quality while the overall population maintains uniformity through controlled crossing of these specialized lines.
