Expert Answer

Variety is a sub-type of a species that has a certain trait in common with other members of that sub-type, and breeds true for that trait.

Strain is a sub-type of a microorganism that has a particular genetic variant. In animal breeding, we might refer to a particular breeding stock for a variety as a strain.
