Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current corn breeding techniques face challenges in developing uniform corn hybrids with desirable traits such as high yield, disease resistance, and uniformity, as they often result in unpredictable performance due to genetic non-uniformity among hybrid plants.
Innovation Solution
The development of the corn variety CV498625, which is a stable inbred line with specific traits like male sterility, herbicide tolerance, and disease resistance, achieved through backcrossing and genetic transformation techniques, ensuring uniformity and desirable characteristics in progeny plants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional corn breeding techniques are used to develop hybrids, then various desirable traits can be combined in a single variety, but the resulting hybrid plants exhibit genetic non-uniformity leading to unpredictable performance
Solution Approach 1:
The breeding process is segmented into distinct phases: developing homozygous inbred parental lines through self-pollination, then crossing these standardized inbreds to produce uniform F1 hybrids. This segmentation ensures genetic uniformity within each phase while allowing trait combination across phases.
Solution Approach 2:
The patent changes the genetic uniformity parameter by enforcing homozygosity in parental inbred lines through multiple generations of self-pollination and selection. This parameter change ensures that all plants in the F1 hybrid generation are genetically identical, making performance predictable while still combining desirable traits from different parental lines.
2Stability of the object's composition
If self-pollination is used to develop uniform inbred lines, then genetic uniformity is achieved, but the breeding process requires multiple generations and extensive selection time
Solution Approach 1:
Homozygous inbred parental lines are developed in advance through multiple generations of self-pollination and selection before the hybridization step. This preliminary action ensures genetic uniformity is established beforehand, allowing the subsequent F1 hybrid generation to immediately exhibit uniformity without requiring additional generational cycles.
3Adaptability or versatility
If cross-pollination is used to produce hybrid plants, then genetic diversity is introduced, but the resulting population is non-uniform and performance becomes unpredictable
Solution Approach 1:
The patent applies different genetic strategies to different parts of the breeding program: homozygous inbred lines are maintained with complete genetic uniformity for parental stocks, while controlled cross-pollination between specific inbred lines produces F1 hybrids with uniform heterozygosity. This local quality approach ensures uniformity is maintained where needed (parental lines and F1 hybrids) while introducing diversity where beneficial (combining traits from different inbreds).
