Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of new inbred corn lines is a slow and costly process that requires expertise, and existing inbred parent corn lines lose commercial competitiveness over time, necessitating the need for improved germplasm with enhanced yield, disease resistance, and adaptability.
Innovation Solution
The introduction of the inbred corn line 7MMSL0005, which is a yellow dent inbred corn line with specific physiological and morphological characteristics, along with methods for producing and breeding corn plants using techniques such as self-pollination, sib-pollination, and tissue culture to create uniform and stable inbred and hybrid corn plants, and the use of transgenic approaches to introduce desirable traits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If traditional inbreeding techniques (self-pollination and sib-pollination) are used to develop new inbred corn lines, then genetic uniformity and purity are improved, but the development time and cost increase significantly
Solution Approach 1:
The patent applies preliminary action by establishing a systematic inbreeding program with predetermined steps (self-pollination for 6-8 generations followed by sib-pollination for 4-6 generations). This pre-planned approach with defined generation targets and selection criteria accelerates the development process while maintaining genetic uniformity, resolving the contradiction between thorough inbreeding and development time.
2Reliability
If multiple generations of inbreeding are performed to develop superior inbred lines, then yield and disease resistance are improved, but the cost of breeding programs increases
Solution Approach 1:
The patent implements self-service by utilizing the corn plant's natural self-pollination capability and selective breeding processes. The inbred lines develop their own genetic stability and disease resistance through controlled self-pollination without requiring external intervention beyond initial breeding decisions. This reduces breeding costs while achieving reliable disease resistance through natural selection and genetic fixation.
3Ease of operation
If existing inbred parent corn lines are used continuously, then breeding program simplicity is maintained, but commercial competitiveness decreases over time
Solution Approach 1:
The patent applies dynamics by creating a flexible breeding framework that allows continuous development of new inbred lines while maintaining operational simplicity. The systematic approach (self-pollination for 6-8 generations, then sib-pollination for 4-6 generations) provides a dynamic pipeline for generating fresh, competitive inbred lines without complicating the overall breeding program structure. This ensures ongoing commercial competitiveness while preserving ease of operation.
