Pure seed is pure seed, right? Well, yes and no. When it comes to seed testing, purity can take on a few different meanings. Some of the distinctions are set out by CFIA, but other tests are used to confirm the presence or absence of a trait or gene.
There are actually four different types of quantifying seed purity — from physical purity, to pure seed, to varietal purity, to trait purity. From there the types of purity may be split even further, for example, measuring gene expression or testing for a gene’s presence or absence. In this episode of Under the Microscope, Holly Gelech, business development manager for Biovision Seed Labs, walks us through each type of seed test and when and why you’d need each one.
