Durum Wheat T17C12D Breeding for Yield and Lodging Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current durum wheat breeding techniques face challenges in combining desirable traits such as high seed yield, disease resistance, drought tolerance, and improved agronomic characteristics in a single variety.
Innovation Solution
The development of the durum wheat cultivar T17C12D, which involves a specific breeding history and genetic modifications, including potential transgenic gene introductions, to enhance traits like yield, disease resistance, and adaptability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional durum wheat breeding techniques are used to combine multiple desirable traits, then the complexity of the breeding process increases, but the ability to successfully combine all desired traits (yield, disease resistance, drought tolerance, agronomic characteristics) in a single variety remains insufficient
Solution Approach 1:
The patent combines multiple parental lines (e.g., 'AC Satcher' and 'Narbonne') that each possess different desirable traits into a single hybrid variety (T17C12D) that expresses all traits simultaneously. This merging of genetic material from multiple sources resolves the contradiction by achieving comprehensive trait combination through controlled cross-breeding rather than attempting to accumulate traits through complex sequential breeding steps.
Solution Approach 2:
The patent employs preliminary selection and characterization of parental lines before hybridization. Parents are pre-screened for specific traits (disease resistance, yield potential, drought tolerance) so that the resulting hybrid inherits a predetermined combination of desirable characteristics. This preliminary action simplifies the overall breeding process by reducing the need for multiple generations of selection and backcrossing.
2Productivity
If wheat varieties are bred for higher seed yield and improved agronomic characteristics, then productivity increases, but the plant may become more susceptible to lodging (falling over)
Solution Approach 1:
The patent applies local quality by selecting and combining specific genetic traits from parental lines that address different local requirements. The hybrid T17C12D inherits yield-promoting genes from one parent and lodging-resistance genes (such as shorter stature genes) from another parent. This allows different parts of the plant to express different qualities - high yield potential in the grain while maintaining structural integrity through controlled plant height, thereby resolving the contradiction between productivity and reliability.
