Maize Inbred Line CJ6085 Hybrid Seed Uniformity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Corn breeding faces challenges in producing high-yielding, agronomically sound plants that are uniformly adapted across the U.S. Corn Belt, as regional growing conditions and specific issues like Gray Leaf Spot infection, cool temperatures, and soil pH levels require tailored traits in hybrids, which are often not uniformly adapted.
Innovation Solution
The development of the maize variety CJ6085, which includes a method for producing hybrid seeds and plants with additional traits such as increased water stress resistance, waxy starch, male sterility, and disease resistance through crossing and backcrossing processes, utilizing transgenes and marker-assisted selection to introduce desired traits into the inbred line CJ6085.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If inbred maize lines are used for hybrid seed production, then uniformity and reproducibility of hybrid seed are improved, but vigor and seed yield of the inbred plants themselves deteriorate
Solution Approach 1:
The patent divides the breeding population into distinct inbred lines through multi-generation self-pollination and selection, creating genetically uniform segments that can be crossed to produce hybrid seed. This segmentation allows the inbred lines to serve as stable parental stocks while the hybrid combinations exhibit vigor.
Solution Approach 2:
The patent performs preliminary self-pollination and selection over multiple generations to establish homozygous inbred lines before crossing. This preliminary action creates genetically uniform parental stocks that ensure reproducibility of hybrid seed, while the subsequent hybrid cross restores vigor.
2Adaptability or versatility
If regional adaptation is prioritized with tailored traits for specific conditions, then performance in specific regions is improved, but uniform adaptation across the U.S. Corn Belt deteriorates
Solution Approach 1:
The patent develops inbred lines with specific trait combinations tailored to particular regional conditions (e.g., drought tolerance for arid regions, disease resistance for humid regions). Each inbred line is optimized for local conditions while maintaining genetic uniformity, allowing regional specialization without sacrificing the uniformity of the inbred stock itself.
