Soybean XB31AG09 Breeding Segmentation and Merging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current soybean breeding processes are time-consuming and resource-intensive, aiming to develop stable, high-yielding varieties with desirable traits like disease resistance, drought tolerance, and improved fatty acid profiles, but few varieties achieve commercial success due to the complexity of combining these traits effectively.
Innovation Solution
The development of the soybean variety XB31AG09, which combines glyphosate resistance, multi-race Phytophthora resistance, and moderate sudden death syndrome tolerance, along with other desirable traits, through careful breeding and selection, enabling improved yield potential and stress tolerance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional soybean breeding processes are used to combine multiple desirable traits, then the variety achieves comprehensive traits including disease resistance and yield, but the breeding process becomes extremely time-consuming and resource-intensive taking 6-12 years
Solution Approach 1:
The patent segments the breeding process by first developing a foundational line with core resistance traits (Phytophthora, sudden death syndrome, cyst nematode) and then using this pre-developed line as a parent in subsequent crosses. This segmentation allows other desirable traits to be introduced more efficiently without repeating the entire multi-year resistance development process.
Solution Approach 2:
The patent performs preliminary action by developing XB31AG09 with multiple disease resistances and agronomic traits before it is used as a parent. This pre-equipped genetic foundation enables faster development of new varieties, as breeders can focus on adding specific traits rather than developing resistance from scratch each time.
2Reliability
If breeders select for multiple resistance traits and high yield simultaneously, then the resulting variety has superior performance, but the selection process becomes increasingly complex with over 500,000 potential varieties to evaluate
Solution Approach 1:
The patent merges multiple resistance traits (Phytophthora, sudden death syndrome, cyst nematode) and agronomic traits (yield, maturity, plant height) into a single integrated variety XB31AG09. This consolidation creates a unified genetic platform that simplifies subsequent breeding programs, as breeders start with a variety that already possesses multiple key traits rather than having to combine them separately.
Solution Approach 2:
XB31AG09 serves as a universal parent that can be used across multiple breeding programs to introduce its resistance and agronomic traits into different backgrounds. This multi-functional variety reduces the need to develop separate resistance lines for different breeding objectives, thereby simplifying overall breeding program complexity.
3Reliability
If breeders pursue stable, high-yielding varieties with multiple resistances, then commercial success increases, but the resource investment and breeding program costs become prohibitively high
Solution Approach 1:
The patent performs preliminary action by developing XB31AG09 with multiple disease resistances and agronomic traits before it is used as a parent. This pre-equipped genetic foundation enables faster development of new varieties, as breeders can focus on adding specific traits rather than developing resistance from scratch each time.
Solution Approach 2:
The patent recovers and utilizes the valuable resistance traits from XB31AG09 through repeated use as a parent in crossing programs. By recovering these proven traits in multiple new varieties, the initial resource investment in developing XB31AG09 is amortized across many commercial varieties, reducing the per-variety development cost.
