Hybrid Corn CH011055 Breeding via Extraction and Segmentation
Solution Overview
Problem
Current corn breeding techniques face challenges in developing hybrid varieties that combine desirable traits such as high yield, disease resistance, and uniformity, while maintaining genetic stability and avoiding self-pollination, which limits the introduction of new genetic traits.
Innovation Solution
The development of the hybrid corn variety CH011055, which incorporates cytoplasmic or nuclear factors for male sterility and genetic modifications conferring traits like herbicide resistance, disease resistance, and altered metabolism, using techniques like backcrossing and genetic transformation to introduce specific alleles or transgenes, ensuring stable expression of desired characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional self-pollination breeding methods are used, then genetic uniformity is maintained, but introduction of new genetic traits is limited
Solution Approach 1:
The patent uses hybridization as an intermediary mechanism between two homozygous inbred plants to introduce new genetic traits. By crossing genetically distinct inbred lines, the invention creates hybrid offspring that combine desirable traits from both parents while maintaining controlled genetic composition through subsequent inbreeding generations.
Solution Approach 2:
The breeding method dynamically transitions between cross-pollination (to introduce genetic diversity) and self-pollination (to stabilize genetics). The process alternates between generating hybrid variability and fixing traits through inbreeding, allowing flexible manipulation of genetic composition across generations.
2Adaptability or versatility
If cross-pollination is used to combine desirable traits, then genetic diversity increases, but control over pollination becomes difficult
Solution Approach 1:
The invention extracts and removes the tassel (male flowering structure) from selected female parent plants to prevent unwanted self-pollination or cross-pollination. This manual removal of the male reproductive organ provides precise control over which plants receive pollen, enabling targeted cross-pollination while eliminating uncontrolled fertilization events.
Solution Approach 2:
The patent introduces pollen as a controllable intermediary substance that is manually applied or naturally transferred under controlled conditions. By managing pollen source, timing, and delivery, the breeding process achieves precise control over cross-pollination events while combining desirable traits from specific parental lines.
3Manufacturing precision
If multiple breeding generations are conducted to develop stable hybrids, then trait uniformity improves, but breeding time increases
Solution Approach 1:
The patent performs preliminary selection and development of homozygous inbred parent lines before the actual hybrid cross. By pre-establishing genetically stable parental varieties with desired traits already fixed through multiple generations of inbreeding, the method reduces the number of generations needed in the hybridization program while ensuring trait uniformity in the final product.
Solution Approach 2:
The breeding program is segmented into distinct phases: inbred line development, hybridization, and hybrid stabilization. Each phase has specific objectives and duration, allowing parallel development of multiple inbred lines that can be crossed simultaneously, thereby reducing overall breeding time while maintaining trait uniformity through systematic progression.
