Determining the Origin of a Seed Based On The Critical Period... By Ed Rosenthal

I wasn't real sure quite how to phrase the tittle but I am looking for something that was published in one of Ed's Bibles back in the 60's or 70's. It was a method for determining the origin of a seed by setting the critical period (dark cycle) a few minutes every day and watching the plant for reaction. His method would get you right down to the parallel.

When I first started growing about 1969 or 1970, I got a bag of (supposedly) "red bud" and salvaged some seeds. I grew this strain for several years plucking phenos and eventually ended up with something I simply called #3. It was great pot for those days but I often wondered what strain it really was. One day I got access to one of Ed's bibles and in the appendix there was a chart and a method that described how to determine the origin of your plants. Since I had always wanted to know, I ran the test and it came right down to 3 degrees (or whatever it was) right though the Columbia. So, I was thrilled to believe that I was actually growing Columbia Red Bud.

I actually grew nothing but that strain for almost 30 years. This was in the day when hybrid seeds were nothing more than a myth to me. I managed to produce my own "feminized" seeds. Although, today we call them hermies. LMAO. I didn't know any better. All I knew was those seeds kept producing female plants. Seeds were cool in those days as "Sensimillia" was still pretty much unheard of around here. I am in shithole Midwest, not Cali. Anything but Mex was about unheard of. LOL

Anyway, I grew this strain for years until I finally bought some good seeds and it's been a different game since.

I still have a handful of those seeds from my last crop 20 years ago. I was thinking about pulling them out and seeing what I get. I remember that it was 4 months to ripen from 12/12. Which really sucked back then. I got 2 crops a year. 2 months in veg and 4 months in flower. Today, I would love to have a nice landrace sativa like that to breed with.

I am wondering if it is worth the trouble. Can you breed the 'hermie' trait out? Before I would consider using them to breed, I would definitely want to determine their origin.

Thus, my original request. Anyone remember or have reference to such a thing from Ed?

Thanks.

Oh, found a picture of what I think is my last crop of that strain. Not 100% sure this is it but I think it is. Might be the #3 x a seed a friend sent me from Amsterdam about 1980
