Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in soybean breeding is to develop stable, high-yielding soybean varieties that are agronomically sound, with improved traits such as disease resistance, drought tolerance, and enhanced nutritional quality, while also addressing issues like herbicide resistance and insect resistance.
Innovation Solution
The development of the soybean variety 01094668, which involves a combination of traditional breeding techniques and genetic modification, including the introduction of transgenic genes for herbicide resistance, disease resistance, and improved nutritional content, along with a specific breeding history that includes backcrossing and selection for desirable traits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If traditional breeding techniques are used to develop soybean varieties, then genetic stability is improved, but breeding time and complexity increase
Solution Approach 1:
The patent applies preliminary action by performing multiple backcrossing generations (BC1, BC2, BC3) before final variety development. This systematic preliminary breeding work establishes genetic stability through repeated backcrossing with the recurrent parent 5X2717D6-C0DNN, allowing the accumulation of desired traits while maintaining genetic consistency before advancing to yield testing and variety registration.
2Adaptability or versatility
If multiple traits are combined in a single variety, then agronomic performance is improved, but breeding complexity increases
Solution Approach 1:
The patent merges multiple desirable traits from different parental lines into a single soybean variety (01094668). Through systematic backcrossing, it combines disease resistance, insect resistance, herbicide tolerance, and improved nutritional quality traits while maintaining the genetic background of the recurrent parent 5X2717D6-C0DNN, achieving multi-trait improvement in one variety.
Solution Approach 2:
The patent applies local quality by introducing specific trait improvements at particular genetic loci through targeted backcrossing. Each backcrossing generation focuses on incorporating specific resistance and quality traits from donor parents while maintaining the overall genetic stability and agronomic performance of the recurrent parent, allowing precise trait placement without disrupting the entire genome.
3Quantity of substance
If genetic modification is used to improve nutritional quality, then nutritional content is enhanced, but regulatory and public acceptance challenges increase
Solution Approach 1:
The patent uses conventional backcrossing techniques to copy and transfer desirable nutritional quality traits from donor parents to the recurrent parent 5X2717D6-C0DNN. By using traditional breeding methods rather than genetic modification, it achieves nutritional enhancement through natural recombination and selection, avoiding the regulatory and public acceptance issues associated with transgenic approaches while still achieving the desired nutritional improvements.
