Importance of Preliminary Trait Purity Testing In Corn Seed Production

Importance of Preliminary Trait Purity Testing in Corn Seed Production
By Brenda Johnson

When producing traited seed, trait purity testing is not an option – it’s both a necessity and a requirement by the trait provider. The seed producer has two options for trait purity testing. One option is conducting trait purity testing on the finished seed lots at the time of bagging only. The second option is...READ MORE

Why Test for Disease Resistance?

Why Test for Disease Resistance
By Raquel Salati

As a trained molecular virologist, my specialty is disease and pathogens, mainly viruses. As plant breeders work to introgress resistance genes into their elite lines, my staff and I put those genes to the test.

Advances in Molecular Biodiagnostics May Help Improve Trade

Advances in Molecular BioDiagnostics May Help Improve Trade
By Ravi Chitrampalam

It’s arguably a company’s biggest headache, not to mention costly: having seed rejected at the port of entry because officials say it tests positive for a pathogen of concern. This may not be the fault of seed testing officials, but rather their reliance on a singular testing method that can’t differentiate live target cells from the presence of dead ones, often associated with a seed treatment...READ MORE
