genetics and landrace heritage
    #112854 - 08/22/08 03:22 PM (8 years, 3 months ago)

so saying you trace a strain all the way back to the landrace indica/sativa plants it came from,  can you reliably say the indica/sativa proportions of the hybrid?  how does that all work?  i'm assuming its a little more complex than just 50/50 splits and stuff but i cant find any real info on dominance between teh two and how hybrids come out.

I really doubt, in most cases, you'd be able to trace a strain back to its landrace origins. I've seen the descriptions of strains listed like "75% sativa, 25% indica", but it doesn't make more sense than that one parent was a pure sativa and the other was this and that, which doesn't really make any sense at all. It is really a question of the different arrangements of different alleles that are exhibited by different phenotypes of the same strain. There are traits and characteristics that sativas exhibit that are different than the ones indicas exhibit, and a hybrid will have traits of some and traits of another, just depending on which ones are dominant and the odds that recessive traits may appear, really...

There isn't a way to define a proportion unless you are talking about individual traits, I'm sure. Usually with hybrids, you'll have a general description of "more sativa" or "indica-leaning", and I think that pretty much suffices, along with a more detailed description of what traits most phenotypes will express (height, side-branches, high, etc.).

well i spent a couple hours yesterday researching strain lineages and after like 6 generations i was getting to the point where parents of strains are landraces.  i have it all charted out for blue mystic and super silver haze (two strains i'm growing) going back to their landrace ancestors.  and isnt it true that a landrace is accepted to be either an indica or sativa?  that was the understanding i got from reading about it a shitload on various places.

What did you turn up for Blue Mystic and Super Silver Haze? What were the names of the land-races?

Anyways, yeah, a true land-race is going to be a pure sativa or a pure indica, but its not like you're going to be able to represent the results of hybridization with percentage numbers. It would be a totally arbitrary measurement that wouldn't actually reflect the nature of the plant.
