polyploidy in autos?

[Zygote]

hi zy, sorry but not quite sure how to read your list... just that you used MTF/LR (F3) as the mother every time.

but that's good to know that you are actually working on a tricot day-neutral (meaning auto, right?) variety. how long have you been doing this, and have you come to some decent percentage of tricot seedlings?

and i guess you meant 'black are dicotyledonous' and not 'dioecious'?

yes day-neutral (means auto)
yes 'black are dicotyledonous' (sorry)

zy, if i understand it correctly than you have both tricot parents in your line, but from different varieties? maybe there is a way to force it, like trying to create polyploid seeds with colchicine?

i've seen some weird pics of polyploids like this one

and a friend told me over the weekend that in the 90s he used to have some bushweed seeds that produced about 1 in 5 tricot and even tetracot (or at least with 3 or 4 leaves per node, he didn't remember about the cotylodons) but they hermied a lot and were not really grade A product

but here we have it: selfpollination over probably many generations, and you get 20% mutant offspring...

That photo is mislabeled, that is called fasciation not polyploid.





A couple of things you can get out of the list.

1. (When outcrossing) Even if one parent is a tricot, the off spring form the cross will only show tricots about ¼ of the time.
2. The more inbred the line is for tricots, the better the outcome. (a F4 is better than a F3)
