Bean Line SVGG1317 for Uniform Hybrid Trait 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 tolerance to environmental stress, as they often result in unpredictable genetic diversity and non-uniform populations.
Innovation Solution
Development of the bean line SVGG1317, 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 backcrossing, and the production of F1 hybrid seeds with consistent characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional breeding methods are used to combine desirable traits, then genetic diversity is increased, but population uniformity decreases resulting in unpredictable performance
Solution Approach 1:
The patent applies preliminary action by first developing homozygous inbred parent lines through multiple generations of self-pollination and selection before crossing them. This preliminary homozygization ensures that when the cross is made, the F1 hybrid population will be uniform. The method also involves preliminary evaluation of parent lines for desirable traits before proceeding to hybridization, ensuring that genetic diversity is intentionally introduced only at the crossing stage rather than through unpredictable segregation.
2Stability of the object's composition
If inbred plants are developed through self-pollination and selection, then population uniformity is achieved, but genetic diversity is reduced limiting trait combination
Solution Approach 1:
The patent merges the benefits of inbreeding (uniformity) with the benefits of crossbreeding (genetic diversity) by developing multiple homozygous inbred parent lines, each with different desirable traits, and then crossing them to produce F1 hybrids. This combining approach allows uniform populations to be achieved while still incorporating genetic diversity from multiple parental sources, enabling the combination of traits like yield, disease resistance, and stress tolerance in a uniform hybrid population.
3Adaptability or versatility
If multiple breeding pools are combined to develop new lines, then genetic diversity increases, but breeding process complexity increases
Solution Approach 1:
The patent segments the breeding process into distinct phases: first developing multiple homozygous inbred parent lines through self-pollination and selection, then evaluating them for specific desirable traits, and finally crossing selected parents to produce F1 hybrids. This segmentation allows genetic diversity to be systematically introduced and managed at each stage rather than all at once, reducing overall breeding process complexity while maintaining genetic diversity.
