LSUAC Hi Protein Rice Cultivar Breeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rice breeding is a time-consuming and unpredictable process due to the complexity of identifying genetically superior plants, with conventional methods lacking control at the DNA level, leading to high research costs and variability in developing new cultivars.
Innovation Solution
Development of the LSUAC Hi Protein rice cultivar through cellular selections in a suspension cell culture system using elevated toxic levels of S-2-aminoethyl-L-cysteine, resulting in a semidwarf line with high protein content, improved yield, and enhanced agronomic traits, adapted for specific growing areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional rice breeding methods are used, then new cultivars can be developed, but the process is time-consuming and unpredictable with high research costs
Solution Approach 1:
The patent applies preliminary action by establishing suspension cell cultures from rice varieties before breeding begins. These cell cultures are pre-screened for protein content and agronomic traits in controlled laboratory conditions, allowing breeders to identify superior genetic material early in the process. This preliminary screening of cell lines for desired characteristics reduces the time and unpredictability of subsequent field breeding operations.
2Reliability
If conventional breeding methods are used, then new cultivars can be developed, but research costs are high due to lack of control at the DNA level
Solution Approach 1:
The patent replaces mechanical/phenotypic selection methods with cellular and molecular-level analysis. By using suspension cell cultures and analyzing protein content at the cellular level, breeders can identify superior genetic traits without expensive and time-consuming field trials. This substitution of mechanical breeding approaches with cellular analysis methods reduces research costs while improving control at the DNA level.
3Manufacturing precision
If cellular selections in suspension cell culture system are used, then high protein content and stable agronomic traits are achieved, but the process requires specialized culture systems
Solution Approach 1:
The patent applies universality by developing a suspension cell culture system that serves multiple functions: it screens for protein content, evaluates agronomic traits, and identifies superior genetic lines all in one controlled environment. This multi-functional approach consolidates what would otherwise require separate breeding operations into a single integrated system, making the specialized culture system more justifiable and efficient.
