Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of new inbred corn lines is a slow and costly process that requires expertise, and existing inbred parent corn lines lose commercial competitiveness over time, necessitating the need for improved germplasm with enhanced yield, disease resistance, and trait technologies.
Innovation Solution
The introduction of the inbred corn line 3ZZXH1005, which is a yellow dent inbred corn line with specific physiological and morphological characteristics, along with methods for producing and treating seeds to increase resistance to stress conditions, and techniques for breeding new inbred and hybrid corn plants using pedigree, backcrossing, haploid breeding, and mutation breeding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional inbreeding techniques are used to develop new inbred corn lines, then new germplasm can be obtained, but the process is slow and costly
Solution Approach 1:
The patent applies preliminary action by using mutation breeding to pre-induce genetic variations in corn lines before traditional inbreeding. This creates a foundation of genetic diversity that accelerates subsequent breeding steps, allowing new inbred lines to be developed faster while maintaining quality standards.
Solution Approach 2:
The patent changes the genetic parameter space by introducing mutated alleles through mutation breeding. This expands the available genetic variation beyond what traditional recombination can provide, enabling faster development of novel inbred lines with desirable traits.
2Productivity
If existing inbred parent corn lines are used repeatedly, then breeding efficiency is maintained, but they lose commercial competitiveness over time
Solution Approach 1:
The patent systematically changes the genetic parameters of existing inbred lines through mutation breeding, creating new alleles and genetic variations. This refreshes the genetic base of parent lines, restoring their commercial competitiveness while maintaining breeding program efficiency.
Solution Approach 2:
The patent skips the traditionally slow process of waiting for natural genetic variation to accumulate over many generations of inbreeding. Instead, mutation breeding rapidly introduces genetic diversity, accelerating the development of competitive new germplasm.
3Stability of the object's composition
If more inbreeding generations are conducted to improve line uniformity, then homozygosity increases, but vigor decreases
Solution Approach 1:
The patent changes the genetic composition parameter by introducing fresh mutations that can restore vigor lost during inbreeding. These new genetic variations provide novel alleles that may compensate for the depression effects of continued selfing, maintaining both uniformity and vigor.
