Hybrid Corn 570076 Breeding for Yield and Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of new hybrid corn varieties is a slow and costly process that requires expertise, and existing hybrids lose commercial competitiveness over time, necessitating the creation of novel varieties with improved characteristics such as increased grain yield and resistance to insects, weeds, and diseases.
Innovation Solution
The development of hybrid corn variety 570076, produced from a cross of inbred varieties SSH88 and LLH37, which exhibits improved grain yield and resistance traits, along with seed treatment options to enhance crop flexibility and protect against adverse conditions, is achieved through careful breeding and selection processes, including self-pollination and cross-pollination techniques to produce uniform and vigorous F1 hybrid progeny.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hybrid corn varieties are developed through traditional breeding processes, then grain yield and resistance traits are improved, but the development time and cost increase significantly
Solution Approach 1:
The patent applies preliminary action by pre-selecting and characterizing parent inbred lines for desirable traits before hybridization. The breeding program systematically evaluates parental lines for grain yield, moisture content, and resistance traits prior to crossing, ensuring that only optimized parents are used to produce F1 hybrids. This preliminary selection and characterization of parental material accelerates the overall breeding timeline while maintaining improvement in grain yield and resistance traits.
2Productivity
If existing hybrid corn varieties are used over time, then production is maintained, but commercial competitiveness is lost due to declining yield performance
Solution Approach 1:
The patent applies parameter changes by systematically varying and optimizing key agronomic parameters in new hybrid varieties, including grain yield potential, moisture content at maturity, and resistance trait profiles. Each new hybrid is developed with modified parameter combinations that outperform existing varieties, thereby extending the productive lifespan of commercially viable corn varieties and maintaining competitiveness over time.
3Object-affected harmful factors
If protective chemicals are applied to control pests and diseases, then crop protection is achieved, but environmental impact and production costs increase
Solution Approach 1:
The patent applies self-service by developing hybrid corn varieties with built-in resistance traits that enable the crop to protect itself against pests and diseases without external chemical intervention. The F1 hybrids inherit resistance characteristics from selected parental lines, allowing the plants to defend themselves naturally against harmful organisms, thereby reducing dependence on protective chemicals while maintaining effective pest and disease control.
