Camelina Sativa SO-70 Yield Stability Low-Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Camelina varieties for commercial production in the USA have limited genetic improvement and low productivity, especially under low-input agricultural conditions, which hinders their adoption as reliable biofuel feedstocks.
Innovation Solution
Development of the Camelina sativa 'SO-70' variety with enhanced reproductive attributes and ability to thrive under dryland, low-input conditions, characterized by increased grain and oil yields, and stable agronomic performance across varying environmental conditions, achieved through conventional breeding methods and potential introduction of transgenic traits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional Camelina varieties are used for commercial production, then limited genetic improvement is achieved, but productivity remains low especially under low-input conditions
Solution Approach 1:
The patent applies parameter changes by developing Camelina varieties with modified genetic parameters through conventional breeding methods. The variety SO-70 exhibits changed parameters including increased grain yield (1,489 lb/ac), increased oil yield (526 lb/ac), and improved seed oil content (34.9%) compared to check lines, while maintaining stability under varying environmental conditions including low-input dryland systems
2Productivity
If Camelina varieties are developed for high productivity, then grain and oil yields increase, but adaptability to varying environmental conditions may be compromised
Solution Approach 1:
The patent achieves universality by developing Camelina variety SO-70 that performs multiple functions: it maintains high productivity across diverse environments (from irrigated to dryland systems), provides stable grain and oil yields, and adapts to varying input levels. The variety demonstrates broad adaptability while consistently delivering improved grain yields (1,489 lb/ac) and oil yields (526 lb/ac) across test locations and years
3Productivity
If genetic improvement is practiced on Camelina, then productivity can be enhanced, but the complexity of breeding programs increases
Solution Approach 1:
The patent applies segmentation by dividing the breeding program into distinct phases: parent selection, crossbreeding, progeny testing, and variety registration. The systematic approach segmented the development of variety SO-70 through multiple generations of selection, evaluating specific traits (grain yield, oil content, adaptability) in separate testing phases across different locations and years, making the complex breeding process manageable and reproducible
