Innovation Solution
The development of the field pea cultivar 4004764, which can be used in crossing, selfing, backcrossing, and genetic transformation to introduce traits like herbicide resistance, disease resistance, and enhanced nutritional quality, and can be edited using techniques like CRISPR-Cas9 for specific genetic modifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional pea breeding methods are used, then existing cultivars can be maintained, but the development of stable, high-yielding cultivars with improved traits remains challenging
Solution Approach 1:
The breeding program segments the development process into distinct phases: selecting parent lines with specific desirable traits, crossing them to create F1 hybrids, selfing to produce F2 populations, and selecting stable lines. This segmentation allows systematic improvement of yield while maintaining stability through controlled breeding steps.
Solution Approach 2:
The patent performs preliminary actions by pre-selecting parent lines with desired traits (disease resistance, insect resistance, drought tolerance) before crossing. This preliminary selection ensures that the resulting cultivars inherit stable, improved traits from the outset, facilitating both high yield and reliability.
2Adaptability or versatility
If multiple traits are combined in a single variety, then agronomic quality improves, but the breeding complexity increases
Solution Approach 1:
The patent merges multiple desirable traits (disease resistance, insect resistance, drought tolerance, high yield) into a single cultivar by strategically selecting parent lines that possess different combinations of these traits and crossing them. The F2 population generation allows recombination of traits, enabling the merging of multiple characteristics while managing breeding complexity through systematic selection.
3Manufacturing precision
If genetic engineering techniques are used to introduce specific traits, then trait precision improves, but the overall breeding program complexity increases
Solution Approach 1:
The patent uses genetic engineering as an intermediary tool to introduce specific traits (such as herbicide resistance or disease resistance genes) into the breeding program. These engineered traits serve as mediators that can be integrated into the traditional breeding process, allowing precise trait introduction while the rest of the breeding program follows conventional methods, thus managing overall complexity.
