Innovation Solution
The introduction of the inbred corn line 6ABSM1577, which is a yellow dent inbred corn line with specific physiological and morphological characteristics, and 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 with improved traits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional inbreeding techniques are used to develop new inbred corn lines, then genetic uniformity and homozygosity are achieved, but the process is slow and costly and requires extensive expertise
Solution Approach 1:
The patent applies preliminary action by using pre-existing inbred lines (6ABSM1577 and other elite inbreds) as starting materials that have already been developed through traditional inbreeding. This allows the breeding program to skip the initial slow inbreeding process and directly work with genetically uniform materials, thereby reducing the overall breeding time while maintaining genetic uniformity.
Solution Approach 2:
The patent uses copying by creating copies of elite inbred lines through self-pollination and sib-pollination methods. The inbred line 6ABSM1577 is self-pollinated to produce copies that maintain its genetic uniformity, and these copies are then used as parent lines for hybrid development, effectively replicating the successful genetic material without requiring re-development.
2Quantity of substance
If existing inbred corn lines are used, then immediate availability is achieved, but they lose commercial competitiveness over time
Solution Approach 1:
The patent applies dynamics by creating a dynamic breeding program that continuously develops new inbred lines and hybrids based on changing commercial requirements. The program maintains a core of established inbred lines while actively generating new varieties with improved traits (disease resistance, yield, quality) to replace aging lines, ensuring ongoing commercial competitiveness.
Solution Approach 2:
The patent uses parameter changes by selecting and breeding for specific trait parameters (yield, disease resistance, plant health, uniformity) to improve the commercial competitiveness of corn lines. The inbred line 6ABSM1577 and its derivatives are developed with enhanced parameters compared to existing lines, making them more commercially viable.
3Stability of the object's composition
If self-pollination and sib-pollination are used to maintain inbred lines, then genetic stability is achieved, but seed production efficiency decreases
Solution Approach 1:
The patent applies segmentation by dividing the breeding program into distinct functional segments: (1) maintenance of inbred lines through self-pollination, (2) creation of hybrids through cross-pollination, and (3) evaluation and selection. This segmentation allows efficient management of genetic stability in inbreds while optimizing seed production through targeted cross-breeding programs.
Solution Approach 2:
The patent uses universality by making the inbred line 6ABSM1577 and its derivatives serve multiple functions: they can be used as parent lines for hybrid production, as check lines in evaluations, and as sources for extracting genetic traits. This multi-functionality increases seed production efficiency by reducing the need to develop separate lines for each purpose.
