Camelina SO-40 Seed Weight and Yield Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current camelina varieties available for commercial production in the USA lack high productivity and broad adaptability, especially in low-input agricultural systems, limiting their use as reliable biofuel feedstocks.
Innovation Solution
Development of the Camelina sativa (L.) variety 'SO-40' through conventional breeding methods, which exhibits increased grain yields, stability under dryland conditions, and high oil content, with seeds being larger and heavier, addressing the need for improved agronomic performance and adaptability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional camelina varieties are used for commercial production, then current available varieties can be grown, but they lack high productivity and broad adaptability especially in low-input agricultural systems
Solution Approach 1:
The patent applies parameter changes by selecting and breeding camelina plants with specific physiological and morphological characteristics including increased seed weight (average 1.61 g/1000 seeds), extended seed filling period (41 days), medium maturity (106 days), and relative tall stature (35 inches). These parameter modifications enable the variety to achieve high productivity while adapting to low-input agricultural systems through optimized growth parameters and resource utilization efficiency
2Productivity
If camelina varieties with high productivity are developed, then grain yield increases, but genetic improvement has been limited in the past
Solution Approach 1:
The patent applies segmentation by dividing the breeding program into distinct phases: establishing the variety through conventional breeding methods, evaluating performance across multiple locations and years, selecting plants with desired traits (increased seed weight, extended seed filling period, medium maturity), and releasing the variety for commercial production. This segmented approach enables systematic genetic improvement while managing complexity through structured breeding protocols and multi-environment testing
3Quantity of substance
If camelina seeds are made larger and heavier, then oil yield increases, but seed weight must be optimized
Solution Approach 1:
The patent applies parameter changes by optimizing seed weight to an average of 1.61 g/1000 seeds, which balances seed size with oil content. The extended seed filling period (41 days) allows adequate time for oil accumulation without excessive weight gain, while the medium maturity period (106 days) ensures optimal oil content achievement. This parameter optimization resolves the contradiction by finding the optimal seed weight that maximizes oil yield rather than simply increasing weight
