Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of stable, high-yielding, and agronomically sound yellow field pea cultivars that exhibit resistance to diseases and insects, tolerance to drought and heat, and improved agronomic quality remains a challenge in existing breeding practices.
Innovation Solution
The development of the field pea cultivar 3997496, which is resistant to Powdery Mildew and has medium maturity, along with methods for crossing, mutagenesis, and transformation to introduce traits such as herbicide resistance, insect resistance, and enhanced nutritional quality, and the use of regenerable cells for tissue culture to produce plants with desired characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional breeding practices are used to develop yellow field pea cultivars, then breeding process is relatively simple, but the cultivars lack resistance to diseases and insects, tolerance to drought and heat, and have limited agronomic quality improvement
Solution Approach 1:
The patent combines traditional breeding methods with modern biotechnological approaches including genetic transformation, tissue culture, and marker-assisted selection to develop cultivars with enhanced disease resistance, insect resistance, and environmental tolerance while maintaining manageable breeding processes
Solution Approach 2:
The patent uses tissue culture and regenerable cells as intermediaries to facilitate the integration of transgenes into the pea genome, enabling the development of disease-resistant and insect-resistant cultivars through controlled in vitro propagation and selection processes
2Productivity
If focus is placed on maximizing grain production, then yield increases, but other agronomic qualities and stress tolerances may be compromised
Solution Approach 1:
The patent develops pea cultivars that simultaneously exhibit multiple desirable traits including high grain yield, disease resistance, insect resistance, drought tolerance, and heat tolerance through genetic transformation and selective breeding, making the cultivar adaptable to diverse environmental conditions while maintaining productivity
Solution Approach 2:
The patent modifies genetic parameters and physiological characteristics of pea plants through transformation with specific genes that enhance stress tolerance and agronomic quality, allowing the cultivar to maintain high yield under varying environmental conditions including drought and heat stress
3Productivity
If genetic transformation and tissue culture methods are used to introduce desired traits, then cultivar improvement is accelerated, but the breeding process becomes more complex and requires specialized facilities
Solution Approach 1:
The patent employs preliminary selection of regenerable cells and establishment of tissue culture protocols before genetic transformation to streamline the breeding process, enabling efficient integration of desired traits while reducing overall process complexity through pre-optimized procedures
Solution Approach 2:
The patent utilizes the plant's own regenerable cells and natural regeneration capabilities in tissue culture to propagate transformed plants, eliminating the need for complex external intervention systems and simplifying the overall breeding process while maintaining high breeding efficiency
