Soybean Variety 5PVKB69 Breeding Stability and Yield
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 environmental tolerance, while existing methods are inefficient and directionally unstable, taking six to twelve years from the first cross to delivering finished seed to farmers.
Innovation Solution
The introduction of the novel soybean variety 5PVKB69, which includes methods for crossing, introgressing transgenic, mutant, or native traits, and characterizing soybean plants to produce stable, high-yielding varieties with improved agronomic characteristics, disease resistance, and environmental tolerance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional soybean breeding methods are used to combine desirable traits, then the resulting varieties achieve high yield and stability, but the development process takes six to twelve years and requires significant resources
Solution Approach 1:
The patent applies preliminary action by pre-screening and selecting parent lines with desirable traits (high yield, disease resistance, environmental tolerance) before initiating the breeding program. This advance preparation of genetically superior parent material accelerates the development process while ensuring the resulting varieties achieve stability and high yield across various conditions
2Productivity
If traditional breeding methods are used to combine multiple desirable traits, then stable high-yielding varieties are produced, but resource efficiency is reduced due to the lengthy six to twelve year process
Solution Approach 1:
The patent employs self-service through systematic selection and evaluation methods where the breeding program itself identifies and selects the most promising parent combinations and progeny. This self-directed approach optimizes resource allocation by focusing efforts on genetically superior lines that naturally exhibit high yield potential and stability, thereby improving resource efficiency while maintaining high productivity
3Adaptability or versatility
If conventional breeding approaches are used to introduce new traits, then the varieties achieve agronomic soundness, but the process lacks directional stability and requires multiple years of testing
Solution Approach 1:
The patent implements feedback through systematic evaluation and selection at multiple stages of the breeding process. Parent lines are selected based on proven performance, progeny are evaluated for trait inheritance and expression, and only those meeting predetermined standards for agronomic soundness and stability are advanced. This feedback-driven selection process ensures directional stability by consistently choosing lines that demonstrate the desired combination of traits across different environments
