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 CV572727, which is an inbred corn plant with specific physiological and morphological characteristics, including the option for cytoplasmic or nuclear factors that confer male sterility or other desirable traits like herbicide tolerance and disease resistance, allowing for controlled pollination and hybrid seed production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional corn breeding techniques are used to develop hybrids, then various desirable traits can be combined, but genetic non-uniformity results in unpredictable performance
Solution Approach 1:
The breeding process is segmented into distinct phases: developing homozygous inbred lines through self-pollination, then crossing these standardized lines to produce uniform hybrids. This segmentation ensures genetic consistency within each phase while achieving trait combination across phases.
Solution Approach 2:
The patent changes the genetic uniformity parameter by enforcing homozygosity in parental lines through multiple generations of self-pollination and selection. This parameter change ensures that all plants in a hybrid population have identical heterozygous genotypes, making performance predictable.
2Stability of the object's composition
If self-pollination is used to develop uniform inbred plants, then genetic uniformity is achieved, but breeding complexity increases
Solution Approach 1:
The patent applies preliminary action by performing multiple generations of self-pollination and selection before the actual hybrid crossing. This preliminary development of homozygous inbred lines simplifies the subsequent hybridization process and ensures uniform results.
Solution Approach 2:
Self-pollination is utilized as a natural mechanism to achieve homozygosity. The plant serves itself by transferring its own pollen, eliminating the need for complex external intervention while achieving the desired genetic uniformity.
3Adaptability or versatility
If cross-pollination is used to produce hybrid plants, then desirable traits from different parents are combined, but genetic non-uniformity occurs
Solution Approach 1:
The patent achieves homogeneity by crossing two homozygous inbred lines, ensuring that all F1 hybrid offspring have identical heterozygous genotypes. This homogeneity in genetic composition provides both uniformity and predictable performance while combining traits from both parents.
