Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current plant breeding techniques face challenges in combining desirable traits such as disease resistance, drought tolerance, and high yield in a single hybrid grain sorghum variety, while maintaining uniformity and stability across different environmental conditions.
Innovation Solution
Development of the hybrid sorghum variety PHLQVBM through crossing proprietary sorghum inbred varieties, incorporating locus conversion and transformation methods to introduce specific traits, and utilizing cytoplasmic male sterility systems for efficient seed production and trait inheritance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional plant breeding techniques are used, then uniformity and stability across environments are maintained, but combining multiple desirable traits (disease resistance, drought tolerance, high yield) in a single hybrid is difficult
Solution Approach 1:
The breeding program segments the combination process by first developing inbred lines with specific traits through separate breeding programs, then combining them in controlled crosses. This allows systematic integration of multiple traits while maintaining uniformity through the structured approach of creating uniform inbred parents before hybridization.
Solution Approach 2:
The patent applies preliminary action by developing and stabilizing inbred lines with specific desirable traits before creating the final hybrid. This preliminary breeding work ensures that each parent line is uniform and stable, which then translates to consistent hybrid performance while combining the desired traits from both parents.
2Productivity
If inbred varieties are developed through traditional breeding, then uniformity is achieved, but the time to combine multiple traits and achieve high yield is extended
Solution Approach 1:
The patent uses preliminary action by pre-developing inbred lines with specific traits before the final hybridization. This allows the complex trait combination process to be broken down into manageable stages, reducing the overall time required compared to attempting to combine all traits in a single breeding program.
Solution Approach 2:
The patent merges the benefits of traditional inbred breeding with modern hybridization approaches. By combining uniform inbred lines with complementary traits in a controlled cross, the program achieves high yield and multiple desirable traits simultaneously in the F1 hybrid, bypassing the time-consuming process of developing such a complex variety from scratch through traditional methods.
3Adaptability or versatility
If cross-pollination is used to create hybrids, then trait combination is enhanced, but control over pollination and seed production becomes more complex
Solution Approach 1:
The patent uses an intermediary approach by employing controlled cross-pollination techniques with careful isolation and hand-pollination protocols. This intermediary control mechanism allows the breeder to ensure cross-pollination between specific parent lines while preventing unwanted self-pollination or cross-contamination, thus simplifying the overall control despite the complexity of hybridization.
