Solution Overview

Problem

Current corn breeding techniques face challenges in developing uniform corn hybrids with desirable traits such as high yield, disease resistance, and uniform germination due to genetic non-uniformity in cross-pollinated plants, which requires the development of stable inbred plants and careful selection processes.

Innovation Solution

The development of the corn variety CV079395, which is an inbred corn plant with specific morphological and physiological characteristics, including the option for cytoplasmic or nuclear factors that can confer male sterility or self-incompatibility, allowing for controlled pollination and the introduction of heritable traits like herbicide tolerance and disease resistance through genetic transformation or backcrossing, ensuring a homogeneous population of inbred seeds and plants.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If cross-pollination is used in corn breeding, then genetic diversity and adaptability 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 homozygous inbred lines through self-pollination to achieve genetic uniformity, then crossing these stabilized lines to introduce genetic diversity. This segmentation allows each phase to optimize for its specific goal without compromising the other.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Homozygous inbred plants are developed and stabilized through multiple generations of self-pollination before the crossing step. This preliminary action ensures genetic uniformity is established beforehand, so that when cross-pollination occurs, the resulting hybrids have predictable and uniform performance.

Inventive Principle:
Principle #10Preliminary action

2Stability of the object's composition

If self-pollination is used to develop homozygous inbred plants, 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:

The breeding program is divided into separate segments: one dedicated to developing homozygous inbred lines through self-pollination (prioritizing uniformity), and another dedicated to crossing these lines (prioritizing diversity). This segmentation resolves the contradiction by allowing each process to optimize for its specific objective.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention combines self-pollination and cross-pollination methods in a sequential breeding strategy. Self-pollination is used first to establish homozygous lines, then cross-pollination is used to create hybrids. By merging these opposing approaches in sequence, both genetic uniformity and genetic diversity are achieved at different stages.

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If multiple breeding generations and selection processes are used to develop superior inbred plants, then desired traits and performance are improved, but breeding time and process complexity increase

Engineering Contradiction:
Improvedesired traitsVSAvoidbreeding time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent employs molecular marker-assisted selection to replace traditional phenotypic selection methods. This substitution allows for more efficient and accurate identification of desired genetic traits, reducing the number of generations needed to develop superior inbred lines while maintaining reliability.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
