Hybrid Corn Variety Breeding for Uniform and Stable Trait Integration
Find Innovative SolutionsGenerate Solutions
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 CH010490, which includes genetic modifications for traits like male sterility, herbicide resistance, and disease resistance, achieved through methods such as backcrossing and genetic transformation, ensuring uniformity and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional breeding techniques are used to develop hybrid corn varieties, 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 developing and maintaining inbred parental lines with predetermined desirable traits before hybridization. The parental lines CV-884850 and CV-821576 were developed through prior breeding efforts to possess specific characteristics (disease resistance, yield potential), allowing the hybrid CH010490 to inherit these traits in a single generation, thus accelerating the breeding process.
2Adaptability or versatility
If multiple desirable traits are incorporated into a single hybrid variety, then agronomic quality improves, but the complexity of breeding and selection increases
Solution Approach 1:
The patent applies segmentation by dividing the breeding program into distinct parental lines, each optimized for specific traits. Inbred line CV-884850 contributes certain desirable characteristics while CV-821576 contributes complementary traits. This segmentation allows breeders to independently develop and evaluate each parental line's contribution to the final hybrid's agronomic quality.
Solution Approach 2:
The patent demonstrates universality through the development of inbred parental lines that serve multiple functions: they are used for hybrid seed production, for evaluating trait inheritance patterns, and as potential parents for future hybrid combinations. The parental lines CV-884850 and CV-821576 have been developed to provide both yield contribution and resistance traits, making them multi-functional breeding materials.
3Reliability
If hybrid corn varieties are developed through extensive breeding programs, then yield and resistance traits improve, but the cost and resource requirements increase
Solution Approach 1:
The patent applies copying by creating true-breeding inbred parental lines that can be replicated and used repeatedly for hybrid seed production. Once the parental lines CV-884850 and CV-821576 are developed with desired disease resistance traits, they can be propagated and used as parents for multiple seasons of hybrid production, amortizing the initial breeding investment across many production cycles.
