Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of new soybean varieties is a time-consuming process that requires precise planning and efficient resource use, aiming to combine desirable traits such as high yield, disease resistance, and tolerance to environmental stresses, while existing methods are inefficient and directionally unstable.
Innovation Solution
The introduction of soybean variety 5PKNT86, which is a stable, high-yielding variety with improved agronomic characteristics, combined with methods for crossing, introgressing transgenic or mutant traits, and characterizing the variety to produce plants with enhanced traits for specific environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional soybean breeding methods are used to combine desirable traits, then the variety can achieve high yield and disease resistance, but the development process takes 6-12 years and requires extensive resources
Solution Approach 1:
The patent applies preliminary action by pre-characterizing variety 5PKNT86 with multiple desirable traits (high yield, disease resistance, stress tolerance) before using it as a parent in breeding programs. This allows breeders to start with a pre-optimized genetic base rather than developing traits from scratch, significantly reducing the 6-12 year breeding cycle while maintaining reliability of trait combination
2Reliability
If multiple crossing and selection steps are performed to achieve stable high-yielding varieties, then the agronomic soundness and yield stability are improved, but the complexity of the breeding program increases
Solution Approach 1:
The patent applies copying by providing variety 5PKNT86 as a standardized, well-characterized parent that can be repeatedly used across multiple breeding programs. Breeders can copy its proven genetic contributions (yield, disease resistance, stress tolerance) into different backgrounds through controlled crosses, reducing program complexity while maintaining yield stability across environments
3Adaptability or versatility
If breeders attempt to combine multiple desirable traits in a single variety, then the overall agronomic performance is improved, but the difficulty of detecting and measuring trait inheritance increases
Solution Approach 1:
The patent applies feedback by providing comprehensive, pre-characterized data on variety 5PKNT86's performance across multiple traits (yield, disease resistance, stress tolerance) and its inheritance patterns. This feedback information allows breeders to track and measure trait inheritance more easily when using 5PKNT86 as a parent, reducing the difficulty of detecting multi-trait inheritance while maintaining versatile agronomic performance
