A8367 Hybrid Corn With High-Amylose, High-Fiber Grain
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing corn hybrids do not effectively produce high amylose content and high total dietary fiber content, which are desirable traits for specialty corn production, and there is a need for hybrids that can maintain high yields and be resistant to environmental stresses while being easier to harvest.
Innovation Solution
Development of the hybrid corn plant A8367, which is bred to have amylose content ranging from 78% to 85% and total dietary fiber content from 30% to 35%, achieved through hybridization and potentially genetic engineering, with traits like male sterility and resistance to diseases and insects, and adapted to specific growing regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If specialty corn hybrids are bred to produce high amylose content and high total dietary fiber content, then the nutritional quality and specialty value are improved, but the yield and resistance to environmental stresses deteriorate
Solution Approach 1:
The patent combines multiple desirable traits (high amylose content, high total dietary fiber, disease resistance, drought tolerance, and commercial yield) into a single hybrid corn variety A8367 through controlled crossbreeding of inbred lines, merging previously separate trait improvements into one integrated solution
Solution Approach 2:
The patent achieves high amylose content (78-85%) and high total dietary fiber (30-35%) by selecting and combining specific genetic parameters from parent inbred lines, changing the compositional parameters of the corn grain to meet specialty requirements while maintaining agronomic performance
2Quantity of substance
If specialty corn hybrids are bred to produce high amylose content and high total dietary fiber content, then the nutritional quality is improved, but the yield deteriorates
Solution Approach 1:
The patent merges high dietary fiber content with commercial yield capability in hybrid A8367, demonstrating that specialty quality traits and productivity can be simultaneously achieved through proper parental selection and hybridization
Solution Approach 2:
The patent changes the grain composition parameters to achieve 30-35% total dietary fiber while maintaining yield at commercial levels, overcoming the traditional trade-off between quality and quantity
3Productivity
If conventional corn hybrids are used, then the yield is maintained, but the amylose content and total dietary fiber content are insufficient for specialty production
Solution Approach 1:
The patent changes the starch composition parameters by selecting parent lines with specific genetic characteristics, resulting in hybrid A8367 producing 78-85% amylose content, a significant increase from conventional hybrids, while maintaining commercial yield

AI summary
A novel hybrid corn plant, designated A8367 is disclosed. The technology relates to the seeds of hybrid corn A8367, to the plants and plant parts of hybrid corn A8367, and to methods for producing a corn plant by crossing the hybrid corn A8367 with itself or another corn plant. The technology further relates to methods for producing a corn plant containing in its genetic material one or more transgenes and to the transgenic plants produced by that method and to methods for producing other hybrid corn plants derived from the hybrid corn plant A8367. Starch from corn seed obtained from A8367 is high amylose corn starch having high total dietary fiber content.
