Corn Inbred 2737P Purple Kernel Color and Disease Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current corn breeding techniques face challenges in developing hybrids with desirable traits such as high oil content, disease resistance, and uniformity, which are essential for maximizing yield and minimizing susceptibility to pests and environmental stresses, while also being difficult to predict and reproduce.
Innovation Solution
The development of a novel inbred corn line, 2737P, which exhibits high anthocyanin content, purple kernel color, and specific agronomic characteristics, along with methods for genetic modification and locus conversion to introduce desired traits like male sterility, herbicide resistance, and disease resistance, allowing for the creation of hybrid seeds with improved qualities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current corn breeding techniques are used to develop hybrids with desirable traits, then traits such as disease resistance and oil content can be improved, but the predictability and reproducibility of these traits remain difficult
Solution Approach 1:
The patent changes the genetic parameters of the corn inbred line by introducing specific mutations (such as the r1-ds mutation and C2/c2 allele combinations) that control anthocyanin pigment production. These parameter changes in the genetic makeup enable predictable purple kernel color and enhanced disease resistance, directly addressing the reliability issue while maintaining manageable breeding complexity through targeted genetic modifications rather than broad breeding approaches
2Object-affected harmful factors
If high anthocyanin content is introduced into corn kernels, then purple kernel color and disease resistance are improved, but the complexity of genetic modification increases
Solution Approach 1:
The patent applies local quality by specifically modifying the aleurone layer of the kernel to produce purple pigment through targeted mutations in anthocyanin pathway genes (such as r1 and C2 loci). This localized genetic modification in the aleurone layer provides disease resistance and the desired purple color without requiring complex whole-plant genetic modifications, thereby improving disease resistance while keeping the genetic modification complexity manageable through focused, tissue-specific changes
