Innovation Solution
Development of novel sweet corn hybrids, HMX4366YS and HMX4370BS, along with methods for vegetative propagation, tissue culture, and genetic modification to introduce traits like male sterility, herbicide resistance, and enhanced nutritional quality, using techniques like backcrossing and genetic engineering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional sweet corn breeding methods are used, then genetic stability is maintained, but yield and eating qualities cannot be sufficiently improved
Solution Approach 1:
The patent segments the breeding process into distinct stages: developing inbred lines with specific traits, creating F1 hybrids through controlled crossing, and separately introducing transgenic modifications. This segmentation allows each component to be optimized independently while maintaining overall genetic stability through controlled combination.
Solution Approach 2:
The patent employs parameter changes by modifying specific genetic parameters through transgenic introduction (adding novel genes for herbicide resistance, insect resistance, or improved eating qualities) while maintaining other genetic parameters stable through controlled breeding methods. This allows selective improvement of yield and quality traits without compromising overall genetic stability.
2Adaptability or versatility
If transgenic modification is introduced to improve eating qualities and nutritional content, then agronomic qualities are enhanced, but genetic stability may be compromised
Solution Approach 1:
The patent uses controlled crossing as an intermediary process between conventional breeding and transgenic modification. By first developing stable inbred lines through conventional breeding and then introducing specific transgenic traits through controlled genetic engineering, the patent acts as a mediator that integrates both approaches while maintaining genetic stability.
Solution Approach 2:
The patent performs preliminary action by developing stable inbred lines with desired agronomic qualities through conventional breeding before introducing transgenic modifications. This preliminary stabilization of the genetic background ensures that subsequent transgenic introductions enhance specific traits without compromising overall genetic stability.
3Reliability
If multiple breeding techniques are combined to introduce desirable traits, then eating qualities and nutritional content are improved, but breeding complexity increases
Solution Approach 1:
The patent segments the complex breeding process into distinct, manageable stages: inbred line development, hybrid creation, and transgenic introduction. Each stage focuses on specific objectives and can be independently optimized and controlled, reducing overall breeding complexity while achieving multiple trait improvements.
Solution Approach 2:
The patent applies local quality by introducing specific transgenic traits at targeted locations in the breeding program rather than attempting simultaneous modification of multiple traits. Each transgenic introduction addresses specific eating quality or nutritional deficiencies while leaving other traits unchanged, simplifying the overall breeding complexity.
