To create the strains in Dutchie go to Products --> Strains --> Add Strain. Ideally, you'll create a strain for every variant type you may have: Sativa, Sativa Dominant Hybrid, Indica, Indica Dominant-Hybrid, 50/50 Hybrid, Pure CBD, CBD Rich, etc.
Update the products in Catalog by individually or bulk editing.
The strain filtering won't populate online unless there are products assigned to them. For example, the 'CBD Rich' filter is under the Carts categories but it's not shown as a filter option for Flower.
