Take cuttings and reproduce it exactly. It’s fairly easy. I did it for 23yrs in my ag/hort business. Cone seed don’t always come true to the parent lineage - there are genetic variations - but cuttings and root division always do.
Thanks for the info.
After more closely reading the *.pdf file, it looks like this is a meristem/lab production issue; the cuttings of albinos didn’t make it due to lack of chlorophyll in cells. Looks like it going to be a cone/seed reproduction situation, instead of simple cuttings, after all. I did meristem production with orchids, back in the 80s, and was very successful. This is a different can of worms. Usually, Redwood cuttings are easy.
