Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Corn breeding aims to combine desirable traits like yield, disease resistance, and uniformity, but existing methods struggle to develop stable inbred plants with predictable performance due to genetic non-uniformity in hybrid populations.
Innovation Solution
The development of the corn variety CV593904, which includes a cytoplasmic or nuclear factor for male sterility and additional heritable traits such as herbicide tolerance and disease resistance, along with a process for producing hybrid seeds by crossing inbred plants to ensure genetic stability and uniformity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cross-pollination is used to combine desirable traits from different plants, then genetic diversity and trait combination are improved, but genetic non-uniformity and performance predictability deteriorate
Solution Approach 1:
The breeding process is segmented into distinct phases: creating diverse hybrid populations through cross-pollination, then separating and selecting uniform individual plants from those populations. This segmentation allows the system to first benefit from genetic diversity in trait combination, then achieve uniformity and predictability in the selected progeny.
Solution Approach 2:
The patent applies local quality by selecting and propagating only those individual plants within the hybrid population that exhibit the desired uniform traits. Each selected plant becomes a localized uniform source, creating pockets of genetic consistency that can be reliably propagated, while the overall breeding program maintains diversity through the initial cross-pollination phase.
2Stability of the object's composition
If self-pollination is used to develop homozygous inbred plants, then genetic uniformity is improved, but breeding flexibility and trait combination capability deteriorate
Solution Approach 1:
The patent employs preliminary action by first creating diverse hybrid populations through controlled cross-pollination before proceeding to self-pollination and selection. This preliminary diverse population serves as a reservoir of genetic variation, allowing breeders to subsequently select for specific uniform traits while maintaining the flexibility to combine different parental lines in various configurations.
3Reliability
If extensive breeding programs are implemented to develop superior inbred plants, then desired characteristics are improved, but time and resource investment increase
Solution Approach 1:
The patent implements feedback mechanisms through systematic evaluation of hybrid populations, where plants are assessed for desired characteristics and selected accordingly. This feedback loop allows for efficient identification and propagation of superior uniform plants, reducing the time required compared to unguided breeding approaches, while maintaining the development of reliable desirable characteristics.
