Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing corn breeding methods struggle to develop hybrids with uniformity and desirable traits such as yield, disease resistance, and drought tolerance, while maintaining genetic stability and commercial viability.
Innovation Solution
The development of the hybrid corn variety CH010466, which includes genetic modifications for traits like male sterility, herbicide resistance, and disease resistance, achieved through backcrossing and genetic transformation techniques, ensuring uniformity and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional corn breeding techniques are used, then hybrid production can be maintained, but uniformity and desirable traits such as increased yield, disease resistance, and improved agronomic qualities are difficult to achieve
Solution Approach 1:
The patent applies preliminary action by developing homozygous inbred lines through multiple generations of self-pollination and selection before creating hybrids. This preliminary development of stable, uniform parent lines ensures that the resulting hybrids will exhibit consistent desirable traits and uniformity, resolving the contradiction between achieving reliable uniformity and maintaining efficient hybrid production.
2Stability of the object's composition
If self-pollination is used to develop homozygous inbred plants, then genetic stability is achieved, but the process requires multiple generations and time
Solution Approach 1:
The patent implements continuity of useful action by employing recurrent selection methods where inbred lines are continuously self-pollinated and selected for desirable traits over multiple generations. This continuous process of self-pollination and selection maintains genetic stability while efficiently progressing toward homozygosity, resolving the contradiction between achieving genetic stability and minimizing time loss.
3Productivity
If cross-pollination is used to create hybrid plants, then heterosis and improved traits are achieved, but uniformity in the hybrid population may be reduced
Solution Approach 1:
The patent applies local quality by creating cross-pollination between specifically selected homozygous inbred lines that each possess particular desirable traits. By carefully choosing parent lines with complementary characteristics and controlling the cross-pollination process, the patent achieves uniformity in the hybrid population while maintaining improved traits through heterosis, resolving the contradiction between productivity and manufacturing precision.
