Hybrid Corn CH010367 Breeding Segmentation and Male Sterility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in corn breeding is to develop hybrid varieties that combine desirable traits such as high yield, disease resistance, and uniformity, while maintaining genetic stability and avoiding self-pollination.
Innovation Solution
The development of the hybrid corn variety CH010367, which includes genetic modifications for traits like male sterility, herbicide resistance, and disease resistance, and is produced through crossing specific inbred parent plants to ensure genetic stability and prevent self-pollination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cross-pollination is used to develop hybrid corn varieties, then genetic diversity and desirable traits are improved, but self-pollination control and genetic stability become more difficult to maintain
Solution Approach 1:
The invention segments the breeding population into distinct inbred parental lines with specific desirable traits, allowing controlled cross-pollination between segments while maintaining genetic stability within each segment through inbreeding
Solution Approach 2:
The patent uses male sterility systems and physical isolation barriers as intermediaries to control pollination, ensuring that cross-pollination occurs only between intended parental lines while preventing unwanted self-pollination or contamination
2Stability of the object's composition
If inbred parental plants are developed through self-pollination, then genetic uniformity is improved, but loss of genetic diversity and inbre depression occur
Solution Approach 1:
The invention merges multiple inbred parental lines, each developed through self-pollination for genetic uniformity, into a hybrid combination that restores genetic diversity and vigor through heterosis while maintaining the uniformity benefits of inbreeding within each parent
3Productivity
If hybrid corn varieties are produced through crossing inbred plants, then yield and desirable traits are improved, but complexity of breeding program and production increases
Solution Approach 1:
The patent applies preliminary action by developing and maintaining established inbred parental lines with known desirable traits before hybrid production, and by pre-establishing male sterility systems or isolation protocols to simplify the actual crossing process
Solution Approach 2:
The invention uses self-service mechanisms such as cytoplasmic male sterility that automatically prevent self-pollination without requiring manual intervention, and natural isolation characteristics of the inbred lines that reduce the need for complex management during hybrid seed production
