Solution Overview

Problem

Current corn breeding techniques face challenges in developing uniform hybrid varieties with desirable traits such as high yield, disease resistance, and uniform germination due to genetic non-uniformity in cross-pollinated plants, requiring the development of stable inbred plants and specific breeding methods.

Innovation Solution

The development of the hybrid corn variety CH095541, which includes genetic loci for traits like male sterility, herbicide resistance, and disease resistance, utilizing cytoplasmic-male sterility and transgenes integrated at a single chromosomal location, along with tissue cultures capable of regenerating plants with specific physiological and morphological characteristics.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If cross-pollination is used to develop corn hybrids, then genetic diversity and trait combination are improved, but genetic uniformity and predictability of performance deteriorate

Engineering Contradiction:

Improvegenetic diversityVSAvoidgenetic uniformity

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The breeding process is segmented into distinct phases: first developing uniform inbred parental lines through self-pollination, then crossing them to produce hybrid offspring. This segmentation allows each phase to optimize for its specific goal - uniformity in parents, diversity in hybrids

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Inbred parental lines are developed and stabilized through multiple generations of self-pollination before the actual hybrid cross. This preliminary action ensures that the parental lines have uniform genetics, which then enables predictable hybrid performance when crossed

Inventive Principle:

Principle #10Preliminary action

2Stability of the object's composition

If self-pollination is used to develop inbred lines, then genetic uniformity and stability are improved, but genetic diversity and adaptability deteriorate

Engineering Contradiction:

Improvegenetic uniformityVSAvoidgenetic diversity

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

Self-pollination is used as a preliminary action to develop uniform inbred parental lines before the actual hybridization. The genetic uniformity achieved through selfing is temporary and serves only to create stable parents for subsequent crossing

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

Instead of directly selfing the final hybrid variety (which would lose heterosis), the process inverts by first selfing parental lines to achieve uniformity, then crossing them to restore genetic diversity in the hybrid offspring

Inventive Principle:

Principle #13The other way round (Inversion)

3Adaptability or versatility

If multiple breeding methods are used to combine desirable traits, then trait combination and adaptability are improved, but breeding complexity and time required deteriorate

Engineering Contradiction:

Improvetrait combinationVSAvoidbreeding complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The breeding program is segmented into separate inbred line development programs and hybrid cross programs. Each segment focuses on specific traits, making the overall complex process more manageable and systematic

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The inbred line development process serves multiple functions: it creates uniform parental material, concentrates desirable traits through selection, and establishes stable genetic lines that can be repeatedly crossed

Inventive Principle:

Principle #6Universality (Multi-functionality)
