Hybrid Corn Variety 980006 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 980006, produced from a cross of inbred varieties SLB01 and XHA25, 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 process becomes slow and costly
Solution Approach 1:
The patent applies preliminary action by pre-selecting and characterizing parent inbred lines (SLB01 and XHA25) for desirable traits including yield components, plant health, and adaptability before crossing. This preliminary characterization of parental germplasm allows the F1 hybrid to inherit improved traits more efficiently, reducing the time required for subsequent breeding iterations while maintaining reliability improvements in grain yield and resistance
2Ease of manufacture
If existing hybrid corn varieties are used over time, then established production systems are maintained, but commercial competitiveness is lost
Solution Approach 1:
The patent applies dynamics by creating a systematic approach to hybrid development that balances stability in production systems with continuous improvement in competitiveness. The method involves dynamic selection of parent lines based on current performance criteria, allowing the breeding program to adapt and produce commercially competitive hybrids while maintaining established production methodologies
3Stability of the object's composition
If multiple inbreeding generations are performed to produce uniform inbred lines, then genetic uniformity is achieved, but the breeding process complexity increases
Solution Approach 1:
The patent applies copying by using defined homozygous inbred parent lines that breed true and are highly uniform. These standardized parental copies can be repeatedly crossed to produce consistent F1 hybrid populations, reducing the need for repeated inbreeding generations and simplifying the overall breeding process while maintaining genetic uniformity
