Soybean Variety 5PVKC48 Breeding for Yield Stability
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 soybean variety 5PVKC48, which is stable and high-yielding, with methods for crossing, introgressing transgenic or mutant traits, and characterizing the variety to produce plants and plant parts with improved agronomic characteristics, including resistance to diseases and environmental stresses, facilitating faster and more efficient breeding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional soybean breeding methods are used to combine desirable traits, then the variety achieves high yield and disease resistance, but the breeding process takes six to twelve years and requires extensive resources
Solution Approach 1:
The patent applies preliminary action by pre-screening and selecting parent lines with desired traits (high yield, disease resistance, stress tolerance) before crossing. The breeding program begins with careful selection of germplasm that possesses the traits needed to meet program goals, establishing a foundation that accelerates subsequent breeding steps while ensuring the final variety meets performance targets.
2Productivity
If multiple crossing and selection steps are performed to achieve stable high-yielding varieties, then the variety shows maximal yield over different conditions, but the process becomes complex and resource-intensive
Solution Approach 1:
The patent applies segmentation by dividing the breeding process into distinct phases: parent line selection, crossing, progeny evaluation, and variety development. Each phase has specific objectives and selection criteria, allowing the breeding program to systematically advance toward the goal of high-yielding stable varieties without overwhelming complexity. The multi-location and multi-year testing is segmented into manageable evaluation stages.
Solution Approach 2:
The patent applies universality by developing varieties that simultaneously achieve multiple desirable traits: high yield, disease resistance, and tolerance to abiotic stresses. The breeding program seeks to combine these diverse traits into a single variety that performs maximally across different environmental conditions, making the variety universally adaptable rather than optimized for a single function.
3Adaptability or versatility
If traditional breeding methods are used with frequent direction changes, then the breeding program can adapt to new goals, but the process becomes inefficient and extends the development time
Solution Approach 1:
The patent applies preliminary action by establishing a comprehensive breeding program framework at the outset, including selection of germplasm with desired traits and predefined breeding objectives. This preliminary planning reduces the need for direction changes during implementation, as the program is structured to systematically achieve multiple goals simultaneously through careful parent line selection and organized crossing schemes.
