Hybrid Corn 980004 Yield and Pest 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
A new yellow dent hybrid corn variety, 980004, is developed by crossing inbred varieties SLA21 and 4XP811, with specific physiological and morphological characteristics, and treated seeds are used to enhance resistance to adverse conditions, incorporating seed treatments that provide additional crop flexibility and cost-effective control against pests and diseases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If new hybrid corn varieties are developed through traditional breeding processes, then improved grain yield and resistance characteristics are achieved, but the development process is slow and costly
Solution Approach 1:
The patent applies preliminary action by pre-selecting and characterizing inbred parent lines (SLA21 and 4XP811) with specific desirable traits before hybridization. The inbred lines are developed and evaluated in advance for yield components, stress resistance, and adaptability, allowing the hybrid to inherit these pre-validated characteristics and reducing the time needed for subsequent breeding cycles.
2Productivity
If existing hybrid corn varieties are used, then current production levels are maintained, but they lose commercial competitiveness over time
Solution Approach 1:
The patent applies parameter changes by systematically evaluating and selecting parent lines based on multiple quantitative parameters including yield components (ear weight, kernel rows, kernels per row), stress resistance levels, and adaptability metrics. The hybrid 980004 combines specific parameter combinations from its parents that optimize both productivity and commercial competitiveness, allowing it to outperform existing varieties.
3Object-affected harmful factors
If protective chemicals are applied to control pests and diseases, then crop protection is achieved, but the need for chemical application increases
Solution Approach 1:
The patent applies self-service by developing hybrid corn variety 980004 with inherent resistance traits to insects, weeds, and diseases through its parental genetics. The hybrid's own biological characteristics provide protection against harmful factors, reducing or eliminating the need for external protective chemicals while maintaining effective pest and disease control.
