Engineering Contradiction Analysis
1Stability of the object's composition
If inbred wheat lines are used for hybrid seed production, then uniformity and repeatability of hybrid seed are improved, but plant vigor and seed yield are reduced
Solution Approach 1:
The breeding program segments the development process into distinct phases: creating highly homozygous inbred lines through multiple generations of self-pollination for uniformity, then crossing these inbreds to produce hybrid seeds that exhibit heterosis for vigor and yield. This segmentation allows each phase to optimize for its specific goal without compromise.
Solution Approach 2:
The invention changes the genetic parameter from homozygosity (inbred lines) to heterozygosity (hybrid plants) to achieve different objectives. Inbred lines are maintained at high homozygosity for uniformity, while hybrid plants are created with heterozygosity to maximize vigor and seed yield through heterotic effects.
2Adaptability or versatility
If multiple breeding objectives are pursued simultaneously, then comprehensive improvement of wheat varieties is achieved, but breeding program complexity increases
Solution Approach 1:
The breeding program uses universal methods and tools that can address multiple breeding objectives simultaneously. Marker-assisted selection, for example, can track multiple traits (disease resistance, yield components, quality attributes) in a single selection process, making the breeding system multi-functional and reducing overall complexity.
Solution Approach 2:
Molecular markers serve as intermediaries between phenotypic traits and genetic loci, enabling indirect selection for multiple traits. These markers facilitate the simultaneous pursuit of diverse breeding objectives by providing a unified selection mechanism that can monitor and select for multiple genetic loci controlling different traits.
