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 CH010384, which includes a cytoplasmic or nuclear factor for male sterility or self-incompatibility, along with genetic modifications that confer traits like herbicide resistance, insect resistance, and disease resistance, is achieved through backcrossing and genetic transformation techniques.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If corn plants are self-pollinated to develop homozygous inbred plants, then genetic uniformity and stability are improved, but genetic diversity and adaptability deteriorate

Engineering Contradiction:
Improvegenetic stabilityVSAvoidgenetic diversity
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The breeding program segments the corn population into distinct homozygous inbred lines through repeated self-pollination, creating genetically uniform segments that can be systematically combined in controlled crosses to generate diverse hybrids with stable genetic composition

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent merges genetically uniform inbred lines through controlled cross-pollination to create hybrid varieties that combine the stability of inbred parents with enhanced genetic diversity and heterosis effects

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If cross-pollination is used to create hybrid plants, then genetic diversity and heterosis are improved, but uniformity in progeny deteriorates

Engineering Contradiction:
Improvegenetic diversityVSAvoidprogeny uniformity
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The patent applies local quality by creating specific hybrid combinations from selected inbred parents, where each hybrid line is developed with particular genetic combinations that provide uniformity within that specific lineage while maintaining overall genetic diversity across the breeding program

Inventive Principle:
Principle #3Local quality

3Productivity

If male sterility factors are introduced to prevent self-pollination, then hybrid seed production efficiency is improved, but plant complexity deteriorates

Engineering Contradiction:
Improvehybrid seed production efficiencyVSAvoidplant complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent employs self-service by using cytoplasmic male sterility factors that automatically prevent self-pollination without requiring external intervention or complex management systems, allowing the plant's own genetics to enforce hybrid seed production

Inventive Principle:
Principle #25Self-service
