Solution Overview
Problem
Existing corn breeding techniques struggle to develop hybrids with uniformity and stability, incorporating desirable traits such as yield, disease resistance, and drought tolerance, while maintaining efficient hybrid production methods.
Innovation Solution
The development of the hybrid corn variety CH010458, which includes genetic modifications for traits like male sterility, herbicide resistance, and disease resistance, achieved through methods like backcrossing and genetic transformation, ensuring uniformity and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional breeding methods are used to develop corn hybrids, then uniformity and stability can be achieved, but the process is time-consuming and lacks efficiency
Solution Approach 1:
The patent applies preliminary action by pre-developing and maintaining inbred parental lines with desired traits before hybrid production. The inbred lines are prepared in advance through repeated self-pollination and selection, so that when hybrid seed production is needed, the parental lines are already ready for crossing, significantly reducing the time required for hybrid development while maintaining uniformity and stability.
2Reliability
If multiple desirable traits are incorporated into corn hybrids, then yield and resistance improve, but the complexity of breeding programs increases
Solution Approach 1:
The patent applies segmentation by dividing the complex breeding program into separate modular components: developing inbred lines with specific traits (disease resistance, yield potential), maintaining these lines independently through self-pollination, and then combining them in controlled crosses. This modular approach allows each trait to be optimized separately in parental lines before combining them in hybrids, reducing overall program complexity while achieving multiple desirable traits.
3Stability of the object's composition
If self-pollination is used to develop homozygous inbred plants, then uniformity is achieved, but genetic diversity is reduced
Solution Approach 1:
The patent applies merging by combining genetically diverse inbred parental lines through controlled cross-pollination to produce hybrid offspring. Each parental line is highly uniform due to self-pollination, but by merging different inbred lines with complementary traits, the hybrid inherits genetic diversity from both parents, achieving both uniformity within each parental contribution and genetic variability in the hybrid combination.
