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 environmental stress tolerance, often resulting in unpredictable performance due to genetic non-uniformity in hybrid plants.
Innovation Solution
The development of the bean line SVGG2118, which is homozygous and uniform, incorporating specific genetic loci for traits like herbicide tolerance, insect resistance, and modified carbohydrate metabolism through genetic engineering techniques, ensuring consistent physiological and morphological characteristics across generations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional breeding methods are used to develop bean varieties, then genetic diversity is increased, but uniformity and predictability of performance deteriorate
Solution Approach 1:
The patent segments the breeding process into distinct phases: developing homozygous inbred lines through self-pollination, evaluating them individually, and then crossing selected lines to produce uniform F1 hybrids. This segmentation allows genetic diversity to be explored in the breeding pool while ensuring uniformity in the final product through controlled crosses of homozygous parents.
Solution Approach 2:
The patent applies preliminary action by first developing and evaluating homozygous inbred lines before producing the final hybrid variety. This preliminary self-pollination and selection phase ensures that parental lines are genetically stable and uniform, which then guarantees uniformity in the F1 hybrid offspring while maintaining access to diverse genetic backgrounds.
2Reliability
If self-pollination is used to develop homozygous lines, then uniformity is improved, but genetic diversity is reduced
Solution Approach 1:
Self-pollination is applied as a preliminary action to develop homozygous inbred lines with uniform genetics. This preliminary uniformity is essential before crossing, as it ensures that the F1 hybrids will be uniform. The genetic diversity is preserved in the broader breeding pool from which these uniform lines are selected.
Solution Approach 2:
The patent uses copying by creating multiple copies of the same homozygous genotype through repeated self-pollination. This produces uniform populations of true-breeding progeny that can be reliably crossed. The copying process ensures genetic stability while the selection of diverse parental lines maintains overall genetic diversity in the breeding program.
3Measurement precision
If multiple breeding generations are evaluated, then trait selection accuracy is improved, but breeding time is extended
Solution Approach 1:
The patent applies preliminary action by conducting multiple generations of self-pollination and evaluation before the crossing stage. This preliminary work ensures that parental lines are fully homozygous and their traits are well-characterized, which improves selection accuracy. The time investment is made in the preliminary phase to ensure reliability in the final hybrid product.
