Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Corn breeding aims to combine desirable traits like higher yield, disease resistance, and uniformity, but existing methods struggle to produce stable inbred plants with predictable performance due to genetic non-uniformity in hybrid populations.
Innovation Solution
The development of the corn variety CV413662, which includes a cytoplasmic or nuclear factor for male sterility and genetic modifications such as herbicide tolerance, insect resistance, and specific metabolic traits, along with tissue cultures capable of regenerating plants with consistent morphological and physiological characteristics.
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 worsen
Solution Approach 1:
The breeding process is segmented into distinct phases: creating diverse hybrid populations through cross-pollination, then separating and selecting uniform individuals through self-pollination and selection. This segmentation allows the system to first gain genetic diversity, then achieve uniformity in selected lines, resolving the contradiction between trait combination and performance predictability.
Solution Approach 2:
The patent changes the pollination parameter from cross-pollination to self-pollination in subsequent generations. This parameter change transforms the population from genetically diverse to genetically uniform, enabling predictable performance while maintaining the desirable traits组合ed in earlier generations.
2Reliability
If self-pollination is used to create uniform inbred plants, then genetic uniformity and performance consistency are improved, but the ability to combine diverse desirable traits worsens
Solution Approach 1:
Cross-pollination and trait combination are performed as a preliminary action in the first generation to create diverse hybrids. Subsequent self-pollination and selection then preserve these combined traits while achieving uniformity. The preliminary cross-pollination step ensures desirable traits are combined before the uniformity step.
Solution Approach 2:
The breeding process is segmented into distinct phases: creating diverse hybrid populations through cross-pollination, then separating and selecting uniform individuals through self-pollination and selection. This segmentation allows the system to first gain genetic diversity, then achieve uniformity in selected lines, resolving the contradiction between trait combination and performance predictability.
3Reliability
If extensive breeding programs are conducted to develop superior inbreds, then desirable characteristics are improved, but breeding time and resource investment worsen
Solution Approach 1:
The patent implements feedback through evaluation of hybrid plants and selection of superior individuals based on observed characteristics. This feedback mechanism accelerates the breeding process by directing energy toward lines that demonstrably exhibit desirable traits, reducing the time required to develop superior inbreds compared to random selection.
Solution Approach 2:
The patent changes the pollination parameter from cross-pollination to self-pollination in subsequent generations. This parameter change transforms the population from genetically diverse to genetically uniform, enabling predictable performance while maintaining the desirable traits组合ed in earlier generations.
