Solution Overview

Problem

The development of new canola cultivars is a time-consuming and unpredictable process due to the complexity of inheritance and the need for precise breeding methods to combine desirable traits such as higher seed yield, disease resistance, and improved agronomic qualities, which requires significant research efforts and resources.

Innovation Solution

The introduction of the canola cultivar DN040845A, which is a high oleic, low linolenic acid cultivar resistant to Blackleg, Fusarium wilt, and White Rust, with genes conferring herbicide tolerance and improved nutritional quality, achieved through traditional breeding and dihaploid methodology, allowing for stable and uniform production with enhanced yield and disease resistance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional breeding methods are used to combine desirable traits, then multiple desirable traits (yield, disease resistance, nutritional quality) can be combined in a single cultivar, but the breeding process becomes time-consuming and unpredictable

Engineering Contradiction:
Improvecombination of desirable traitsVSAvoidbreeding process duration
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent employs molecular markers as intermediary tools to facilitate trait combination. These markers serve as genetic signposts that enable breeders to track and combine multiple desirable traits (yield, disease resistance, nutritional quality) in a systematic and predictable manner, significantly reducing the time required for traditional breeding while maintaining the ability to combine complex trait combinations in the DN040845A cultivar.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If conventional breeding approaches are employed, then cultivar development can proceed with standard resources, but the process lacks predictability and requires significant research efforts

Engineering Contradiction:
Improvepredictability of breeding outcomeVSAvoidbreeding methodology complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements molecular marker-assisted selection that provides continuous feedback on the genetic composition of breeding lines. This feedback mechanism allows breeders to monitor the presence and combination of desirable traits in real-time during the breeding process, enabling informed selection decisions and significantly improving the predictability of breeding outcomes without requiring overly complex methodologies.
