Monsanto Unveils Second-Generation Yieldgard VT

The initial products will be YieldGard VT Rootworm/RR2 and YieldGard VT Triple, which include the YieldGard Corn Borer trait through conventional breeding methods. Both varieties are targeted for limited introductions in the US in 2007.

The seed was developed through an advanced technique called Vector-Stack Transformation, or “VecTran.” VecTran utilizes a cleaner, more natural agrobacterium-mediated insertion process, rather than a gene gun, as traits were often introduced in the past. With VecTran, two or more genes containing the desired traits are delivered through a single insertion process into the plant chromosome, on which optimal performance of the stacked traits is achieved. The result, according to Monsanto, is a stacked-trait hybrid with “a highly active and more consistent promoter of the rootworm protection gene, which is more effectively distributed throughout the root system.”

“For farmers, this will mean they get stacked-trait hybrids with improved consistency, with even better insect control and higher yield potential than current YieldGard products on the market,” said Dave Rhylander, director of traits for Monsanto.
