Summary
Insect-protected soybean (SIP) demonstrated no significant differences in agronomic or survival traits compared to conventional soybean. These findings support the global transportability of data for genetically modified crop environmental risk assessments.
Area of Science:
- Agricultural Science
- Biotechnology
- Environmental Science
Background:
- Genetically modified (GM) crops undergo rigorous environmental risk assessment (ERA) before commercialization.
- Insect-protected soybean (SIP) produces Cry1A.105 and Cry2Ab2 proteins for lepidopteran pest resistance.
- Plant characterization data is crucial for regulatory submissions worldwide.
Purpose of the Study:
- To compare SIP soybean with conventional soybean in plant characterization trials.
- To fulfill global regulatory agency requirements and address China-specific considerations.
- To evaluate the consistency of risk assessment conclusions across different regions and methodologies.
Main Methods:
- Multi-location field trials were conducted in the USA and Brazil across different seasons and germplasm (temperate, tropical, subtropical).
- Soybean entries with and without the SIP trait were planted in replicated trials.
- Agronomic, phenotypic, plant competitiveness, and survival characteristics were assessed.
Main Results:
- No differences were observed between SIP soybean and conventional soybean in evaluated characteristics.
- Results were consistent regardless of genetic background, growing region, season, or testing methodology.
- Risk assessment conclusions remained the same, indicating no change in plant pest/weed potential.
Conclusions:
- The evaluated insect-protected soybean exhibits no altered agronomic, phenotypic, competitiveness, or survival characteristics.
- These findings support the concept of data transportability for GM crop environmental risk assessments across diverse global regions, seasons, germplasm, and methodologies.
