Stoned shower questions about pollen chucking

[800lbGuerrilla]

As I understand it, a backross is done by crossing male offspring of a pollination back to the mother plant, stabilizing (mostly) for the traits of the mother by the BX3 ('cubed') generation.

Say you didn't have a mother plant but you did have a few S1 beans all from the same plant. If you repeatedly crossed the male BXs back to the S1 females, would it produce similar results? If not, what would it do?

Normally we want to produce regular seeds from a female plant, but what if we wanted to do this from a male plant? (because reasons) If you repeatedly pollinated the female BXs with pollen from the original father, would it stabilize for the traits of the father?

I'm curious to see what would happen if you found some outstanding male plants and backcrossed them, then grew out the seeds to see what the females were like.

Imho, it's plant count and selection that's important. Although there are always exceptions to the rule.

I think you are correct about bx's. In theory if you planted seeds from 2010, and 2018, then let the plot go to seed. Then used the seeds you get from the 2018 plants, that would be bx'ing as well.

If limited on plant count or space, i'd personally still open pollinate several males and females together. Imo it keeps a healthy gene pool.
If for instance I had 1 mum and 1 dad, then open pollinated cuts, harvested seed. Then bx over, and over, and over again it'd get a bit inbred. Might have an undesirable effect further down the road.

Nothing at all wrong with experimenting with cuts and bx's, imo just have a good amount of backup seed.

Most of all just have fun, chuck away!

I'm trying to learn hear, what is a bx? I know what an s1 is.

This is a pretty good article on the subject:

Essentially it is a method of breeding a plant with itself, usually used when no male is available or the female isn't true-breeding if i'm understanding things correctly.
